【Pacific Auto Network Technology Channel】 1.6L was once the first choice for family cars because of its sufficient power and relatively low fuel consumption. However, with the improvement of consumption level, the size of family cars is getting bigger and bigger, and the power of 1.6L displacement is just enough. If the vehicle is fully loaded, it will be a bit of a small horse-drawn cart, and the driving pleasure has long been gone. 2.0L displacement power is sufficient, but high fuel consumption is inevitable. To make a compromise, 1.8L displacement power and fuel economy are the most suitable. I also saw this opportunity, and developed a brand-new 1.8L engine in five years. This engine code is EC8, which is currently mounted on Dongfeng models. This issue will bring you the technical analysis of Dongfeng EC8 1.8L CVVT engine.

　

Wonderful review of the last issue

　

● Basic engine parameters

● Research and development background of ●EC8 engine project

　　The research and development project of EC8 1.8L engine was put forward at the board of directors of Shenlong Company as early as April 2008, and was officially put into production in April 2013. The whole project development took five years.

　　In the two years before April, 2010, China market analysis and product technical scheme determination were mainly carried out. According to market analysis and laws and regulations, 1.8L will be the gold emission in the household market, and the power performance of 1.8L can best meet the household demand, while the fuel consumption and carbon dioxide emission also meet the environmental protection requirements.

● Fuel consumption of ●1.6L and power of 2.0L displacement.

　　EC8 is a brand-new engine launched by PSA for China market. EC8 engine claims to have the fuel consumption of 1.6L displacement engine and the power of 2.0L displacement engine, and its performance level is in the advanced position of naturally aspirated engine.

　　It can be seen from the EC8 engine diagram that about 90% of the peak torque has erupted in the engine at 1500 rpm, and the torque curve is relatively gentle and lasts until 6000 rpm.

　　It has good dynamic performance in the daily use speed range, and reaches the peak torque at the earliest in the same class. The most intuitive feeling is that when the start accelerates, the low speed is very fast. The output that can be obtained in the 1500-2000 shift range that Chinese people are used to can be described as a little bit of power and a steady stream.

　　With the power of the 2.0L displacement engine, where does the fuel consumption of the 1.6L displacement engine come from? Of course, it depends on technology. For example, EC8 engine adopts cylinder honing technology, micro-grooved tile technology, variable displacement pump, DLC coated hydraulic tappet, intelligent timing gear damping technology, belt and so on. Listen to me together.

　

Before writing this article, Xiao Bian also visited the production workshop of EC8 engine. If you are interested, you can click the following link:

　

● Flat-top honing and micro-grooved tile technology

　　In terms of process flow, the cylinder block of EC8 engine is carried out in a small number of times by gradually adding power. In the last finishing process — — Flat-top honing

　　Flat-top honing can shorten the early running-in process and improve the fuel consumption and engine oil consumption during the running-in period. It can form a multi-reticulated small platform, which can greatly improve the lubrication condition of the friction pair, prolong the service life of the cylinder hole and piston ring friction pair and prolong the time. This technology is also widely called "pre-running-in" by experts, which can minimize the running-in wear of users when driving new cars, improve the reliability of vehicles to a greater extent, and save users’ maintenance costs.

　　In addition, crankshaft bearing has also adopted the micro-grooved tile technology. Micron grooves are machined on the surface of bearing bush by special machining method. The application of micro-grooved tile technology improves the compliance of bearing bush and accelerates the early running-in between bearing bush and crankshaft. Improve the fluidity of lubricating oil in the minimum oil film thickness area and enhance the cooling effect of engine bearing bush; The distribution area of lubricating oil film along the width direction of bearing bush is larger, which can increase the thickness of oil film in most high-pressure working areas and prevent the bearing bush from sticking.

　　The application benefits of micro-grooved tile technology are to reduce the mechanical loss of moving parts and improve the engine efficiency; Improve the reliability of moving parts and prolong the service life.

　　The combination of cylinder flat-top honing technology and crankshaft bearing micro-groove tile technology reduces the power consumption in crankshaft operation engineering. The inspection in the assembly workshop shows that the friction of crankshaft rotation needs to consume 3.6N·m engine torque.

● Variable pump

　　There is also an oil pump directly connected with, and the operation of the oil pump also consumes a part. According to relevant foreign research reports, the use of variable displacement oil pump can generally reduce the fuel consumption of the engine by 1%-2%. To reduce the power consumption of the oil pump, it is necessary to match the oil supply of the oil pump with the actual oil demand of the engine. The use of variable displacement oil pump can meet this requirement.

　　The variable displacement oil pump used in EC8 engine is provided by Magna Powertrain (Changzhou) Co., Ltd.. EC8 oil pump is a variable displacement vane pump, which can be mainly divided into sliding variable vane pump and swinging variable vane pump. The variable principle of the two types of vane pumps is basically the same: the eccentricity between the outer adjusting ring and the rotor is changed by sliding or swinging, and then the displacement of the vane pump is changed.

　　When the feedback oil pressure reaches the variable set value, it is compressed, and the outer adjusting ring slides or swings, so that the eccentricity between the inner ring and the outer ring of the blade is reduced, and the variation of the oil pressure cavity formed between the blade and the inner and outer rings is also reduced correspondingly during the operation of the oil pump, thus reducing the oil pump flow; When the feedback oil pressure decreases, the spring gradually returns to reset the adjusting ring.

　　Main oil passage pressure feedback pressure control mode, which takes the feedback pressure point as the main evaluation point of engine pressure, has small pressure fluctuation and is close to the main lubricating parts, and can accurately reflect the engine oil pressure demand. By adopting main oil passage pressure feedback, the pressure control is more accurate and close to the engine demand, and the oil pump efficiency is higher.

　　The variable displacement pump keeps the pressure of the main oil passage of the engine at medium and high speed at a relatively constant value, which can meet the engine oil demand, reduce power consumption and play the role of energy saving and emission reduction. The variable displacement vane oil pump of EC8 engine is at the top level in China, with low power consumption and stable oil pressure control. Users can reduce engine power consumption and fuel consumption when driving a vehicle.

●DLC coated hydraulic tappet

　　The working surface of EC8 hydraulic tappet is also coated with Diamond-like Carbon for short. The surface of DLC coating is black, which has comprehensive excellent properties such as stable quality, good adhesion with matrix, good wear resistance, low friction coefficient and good corrosion resistance.

　　The hardness of DLC coating can reach 8000HV, the friction coefficient is as low as 0.05~0.2, and the coating thickness is 0.5-10μ M, the highest heat resistance reaches 800℃.

　　After the tappet is coated, the surface friction coefficient is significantly reduced and the hardness is higher, which significantly improves the wear resistance of the tappet surface and greatly reduces the friction loss between the cam and the tappet surface. While reducing the working noise, it also reduces the power consumption of the engine, thus achieving the purpose of reducing fuel consumption and reducing the cost of car use.

● Intelligent timing gear damping technology

　　Through the special formal gear profile design, a controlled and periodic phase interference is formed to eliminate the torsional vibration of camshaft and reduce the dynamic tension of belt.

　　The processed crankshaft timing gear is approximately oval, which can significantly reduce the timing error of camshaft, effectively reduce the dynamic tension of belt, effectively reduce the dynamic and static axle load and improve the service life of belt.

　　It can be seen from the curve that the vibration of the intelligent timing system is reduced and the engine runs quieter. According to reports, the life of the intelligent timing system is equivalent to that of the engine. The belt tension is reduced and the bearing life is effectively improved. It reduces the noise and vibration of the user’s timing system when driving, and improves the driving comfort of the vehicle.

　　EC8 piston adopts the latest technology of FM-Federal-Mogul Company: ELASTOVAL II structure and fully floating piston pin, which optimizes the piston design structure, removes the back mass of piston ring support area, reduces the piston weight and friction loss, and realizes the lightweight of the piston while maintaining sufficient strength of the piston. Elastoval II comprehensively considers the skirt, thickness, profile and other factors, combined with the cylinder clearance and pin hole eccentricity, in order to achieve the best energy-saving and noise-reducing effect, and is conducive to reducing fuel consumption and increasing its fuel.

　　EC8 improves the engine performance to a great extent by increasing the volume of the piston head projection to 11. The special piston structure design also improves the reliability of engine operation and reduces the cost of users’ cars.

●CVVT timing technology

　　CVVT is a technology that changes the opening time of camshaft by electro-hydraulic control system, so as to control the required valve overlap angle. This is not a novel automobile technology. Now many engines have adopted this mature and reliable technology.

　　EC8 engine adopts the VVT technology of INA, which can adjust the intake valve timing and phase in a wide range of angles to ensure that the engine can meet the requirements of middle and low speed and high speed at the same time. The driving comfort, fuel economy and emission are obviously improved. CVVT technology can ensure the charging efficiency of the engine under different working conditions and improve the low-speed end torque by 5-10%. 5-8% high-speed power is increased, so that users can get better power output when starting at low speed, and high engine power is maintained at medium and high speed. The fuel economy can be improved by 1-3%, making the vehicle more fuel efficient. Under the limited NOx level, HC emission can be reduced by 25% at most, and the stability at idle speed is improved, and the driving comfort is better.

　　Summary:Throughout the whole paper, EC8 engine should have many advanced engine technologies besides the original mature, stable and reliable technologies. The development time is relatively short, the cost is relatively low, and the existing market resources can also be used to some extent. The same is true from the user’s point of view. What users are most worried about is whether the performance is stable or not, and it is not easy to buy accessories when there is a fault, which just solves these problems. With five years’ unremitting efforts, the brand-new EC8 engine has been developed with "high efficiency, low consumption and high reliability" in consideration of power, fuel consumption, comfort and reliability. The slogan of the power of the 2.0L engine and the fuel consumption of the 1.6L displacement engine will never be groundless.

General Secretary of the Supreme Leader issued a great call to "compose a more splendid chapter of Socialism with Chinese characteristics in the new era" at the 20th Party Congress. What kind of more gorgeous badge is this? In the face of the stormy international environment and the arduous and arduous task of domestic reform, development and stability, can we write and how to write a more gorgeous chapter? To forge ahead in a new journey, we must grasp and answer these major questions well and create new great achievements with new great struggles.

　　The 20th National Congress of the Communist Party of China painted a magnificent picture of Socialism with Chinese characteristics in the new era.

　　Bear the eternal great cause in mind, and the centenary only ushers in the prime of life. The 20th National Congress of the Communist Party of China made a macro-prospect of the two-step strategic arrangement for building a socialist modernization power in an all-round way, further clarified the overall goal of China’s development by 2035, described the beautiful picture of achieving the goal of the second century, and focused on the strategic tasks and major initiatives for the next five years. This series of strategic arrangements, objectives and tasks have defined the timetable and road map for building a socialist modern power in an all-round way, and drawn a grand blueprint for building a socialist modern country in an all-round way and comprehensively promoting the great rejuvenation of the Chinese nation with Chinese modernization.

　　The five years from the 20th National Congress of the Communist Party of China is a crucial period for building a socialist modern country in an all-round way. The Party’s Report to the 20th CPC National Congress made arrangements for all aspects of work in all fields. These important arrangements cover various fields such as reform, development and stability, internal affairs, foreign affairs and national defense, and governing the party, country and army. They are an organic whole determined according to the "five in one" overall layout and the "four comprehensive" strategic layout, profoundly embody the China characteristics, essential requirements and major principles of Chinese modernization, and are action guides for leading and promoting the comprehensive construction of a socialist modernized country to make a good start.

In terms of overall development and security, China’s national security system and capabilities will be comprehensively strengthened, and national defense and military modernization will be basically realized. The long-term goal of socialist modernization is basically realized, which fully reflects that the new era is an era in which people of all ethnic groups in China unite and struggle, constantly create a better life, and gradually realize the common prosperity of all people.

　　According to the two-step strategic arrangement, from 2035 to the middle of this century, we will continue to struggle on the basis of basically realizing modernization, and by the centenary of the founding of New China, we will build China into a prosperous, strong, democratic, civilized, harmonious and beautiful socialist modernization power. By then, China’s material civilization, political civilization, spiritual civilization, social civilization and ecological civilization will be comprehensively improved, the national governance system and governance capacity will be modernized, and China will become a country with leading comprehensive national strength and international influence, and the common prosperity of all people will be basically realized. Our people will enjoy a happier and healthier life, and the Chinese nation will stand among the nations of the world with a more high-spirited attitude. With a history of more than 5,000 years of civilization, the Chinese nation is full of unprecedented vitality and will make new and greater contributions to all mankind.

　　In the new era, the magnificent prospect of Socialism with Chinese characteristics’s more splendid pageant has begun, and the new journey of building a strong country and national rejuvenation is encouraging and inspiring. Accomplishing the central task and implementing the two-step strategic arrangement, China’s population of more than 1.4 billion will step into a modern society as a whole, exceeding the total population of developed countries, which will completely rewrite the process, territory and situation of world modernization, expand the ways for developing countries to move toward modernization, make scientific socialism glow with new vitality in China in the 21st century, and write an unprecedented glorious chapter in the history of human development.

　　We have sufficient confidence to write a more splendid chapter of Socialism with Chinese characteristics in the new era.

　　In the new era, under the strong leadership of the CPC Central Committee with the Supreme Leader as the core and under the scientific guidance of Socialism with Chinese characteristics Thought of the Supreme Leader in the new era, we have made extraordinary achievements in stabilizing the economy, promoting development, fighting poverty, building a well-off society, controlling epidemics, resisting major disasters, coping with emergencies and turning crises into crises. Those world-famous human miracles, those indomitable struggles in spite of difficulties, and those tenacious struggles in spite of rain and shine are all engraved in the footsteps of historical progress, providing us with strong determination and motivation to make unremitting efforts and forge ahead bravely. Striving for a new journey, the prospect is extremely bright; Writing a new chapter is more emboldened.

　　"Two Establishments" is the greatest confidence. To March on a magnificent journey, we need to lead the core to steer the direction; To achieve great achievements in the future, we need scientific theory to guide us. Since the new era, it is the "two establishments" that lead and ensure the cause of the party and the state to overcome the difficulties and obstacles that followed and achieve remarkable achievements. In the face of the "three-phase superposition" and the new normal of economic development, it is proposed to implement the new development concept, build a new development pattern and promote high-quality development. China’s economy has climbed over the hill and achieved a historic leap; In the face of the epidemic in the century, it is proposed to always adhere to the people first, life first, and efficiently coordinate epidemic prevention and control and economic and social development. China has created a miracle that a populous country has successfully emerged from the epidemic in the history of human civilization; Facing the headwinds and counter-currents in the century-old changes, this paper puts forward that we should firmly stand on the right side of history and the side of human civilization and progress, promote the construction of a community of human destiny, open up new situations in changes, and turn crises into opportunities in chaos … … The key choices, overall strategic plans, and a series of far-sighted new ideas, ideas and strategies have fully demonstrated the historical initiative, extraordinary theoretical courage, outstanding political wisdom and strong mission of the Supreme Leader General Secretary as a Marxist politician, thinker and strategist, and fully demonstrated the truth power and practical power of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era. Practice has fully proved that ""Two Establishments" is the decisive factor to promote the historic achievements and changes in the cause of the party and the state, the greatest certainty, the greatest confidence and the greatest guarantee to overcome all difficulties and obstacles and deal with all uncertainties, and it is of decisive significance to the development of the cause of the party and the state in the new era and to promote the historical process of the great rejuvenation of the Chinese nation. Soak in the wind and rain, quench into steel. We have incorporated the comprehensive and strict administration of the Party into the "four comprehensive" strategic layout, comprehensively strengthened the Party’s leadership, and systematically improved the Party’s leadership system. After revolutionary forging since the new era, the Party has become stronger and more energetic, and its political leadership, ideological leadership, mass organization and social appeal have been significantly enhanced, and it has always been a strong leadership core in the historical process of upholding and developing Socialism with Chinese characteristics. On the way forward, as long as we firmly support the "two establishments", resolutely implement the "two maintenances", unite more closely around the CPC Central Committee with the Supreme Leader as the core, fully implement the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, unite as one and keep pace, we will certainly be able to overcome various risks and challenges and create new great achievements.

　　The people are the most solid support. Jiangshan is the people, and the people are Jiangshan. The great achievements of the new era are made by the party and the people. From the model of the times to the most beautiful figures, from the dim light of mortals to heroic feats, the figures of dreams and dreams, and the "you, me and him" who strive for progress show the enterprising attitude, ambition and creative power of the people of China in the new era. In the new era, our party firmly insists on doing everything for the people, relying on the people, ruling for the people and relying on the people, constantly solving the people’s urgent difficulties and worries, and constantly realizing the people’s yearning for a better life; Develop people’s democracy in the whole process, respect the people’s dominant position and initiative, let the people participate more extensively and deeply in the management of state and social affairs, and fully stimulate the wisdom and strength contained in the people. In the new era, the people of China are more confident, self-reliant and self-reliant, greatly enhancing their ambition, showing unprecedented historical consciousness and initiative, and becoming an inexhaustible source of strength to promote the development of the cause of the party and the country. "if you can use all your strength, you will be invincible in the world." China people’s tenacious vitality, deep cohesion, tenacity and endurance, and great creativity are the fundamental forces for us to March forward in rain or shine. As long as we always take the promotion of people’s well-being, the all-round development of people and the common prosperity of all people as the starting point and the end result, respect people’s creation, concentrate people’s wisdom, share weal and woe with the people, and unite with the people,We will certainly be able to comprehensively promote the great rejuvenation of the Chinese nation with Chinese modernization.

　　Great struggles accumulate valuable experience. It seems to be the most extraordinary, but it is easy but hard to achieve. Since the new era, the complexity of the situation we are facing, the severity of the struggle and the arduous task of reform, development and stability are rare in the world and history. The overall situation of the great rejuvenation strategy of the Chinese nation and the great changes that have never happened in the world in a century have stirred up each other. China’s reform and development have entered a critical period and deep water areas, and the task of reform, development and stability is arduous and arduous. The party United and led the people to overcome difficulties, forge ahead, and promoted the cause of the party and the state to stand at a new historical starting point. We have always maintained our strategic strength, carried forward the spirit of struggle, calmly responded to the impact of multiple unexpected factors at home and abroad, unswervingly followed our own path, and "let the wind and waves rise and sit firmly on the fishing boat." In the face of the complicated situation in which various contradictions are intertwined, we adhere to the problem orientation, grasp the main contradictions, and open up the work situation with solving practical problems as a breakthrough, so as to "make full use of everything at once". In the face of many dilemmas and difficulties, we insist on using the system concept to observe the situation, analyze problems, scientifically demonstrate, compare and select the best, and control the complex situation with overall consideration. "It is still calm to fly in chaos." The party led the people in a great struggle with many new historical characteristics, which accumulated valuable experience for us to bravely move forward in the new journey. As long as we strengthen our strategic self-confidence, strengthen our belief in winning, dare to face up to problems, be good at discovering problems and be brave in solving problems,Deal with the overall and local, current and long-term, macro and micro, major and minor contradictions, special and general relations, do a good job in systematic planning and strategic planning, and concentrate on doing your own thing well. Even in the face of high winds, high waves and even stormy waves, the great ship China can break through the waves and make steady progress.

　　The material foundation is more solid. General Secretary of the Supreme Leader pointed out: "China’s development is still in an important period of strategic opportunities" and "China’s basic characteristics of sufficient economic potential, strong resilience, large room for maneuver and many policy tools have not changed". Strong material foundation, abundant development kinetic energy and huge development potential give us more confidence in pursuing our own development in an unstable and uncertain world. The bottom spirit comes from strength, vitality and potential. Today, China is the second largest economy in the world, and its status as the largest country in manufacturing, trade in goods and foreign exchange reserves has been continuously consolidated and improved. From 2020 to 2022, under the difficult situation of global epidemic and high inflation, China not only stabilized the economic market, kept the bottom line of people’s livelihood, and maintained social stability, but also kept ahead among the world’s major economies with an average annual growth rate of about 4.5%, achieving medium-high growth on the basis of a high base. "Space House" roams the sky, "Struggler" dives 10,000 meters deep, online consumption and classes on the cloud are in full swing, 22 free trade pilot zones cover the East, West, North, South and South China, and Hainan Free Trade Ports set sail, and the first five national parks spread the picture of harmonious coexistence between man and nature … … China’s global innovation index ranked twelfth in 2023, and the added value of new industries, new formats and new models accounted for more than 17% of GDP in 2022.The social security network has become more and more dense and the level of security has been steadily improved, and it has embarked on a road of development with higher quality, more efficiency, fairer, more sustainable and safer. As long as we firmly grasp the primary task of high-quality development, earnestly implement the new development concept and accelerate the construction of a new development pattern, we will certainly be able to open up new fields and new tracks for development and open up a broader development space for Chinese modernization.

　　The system guarantee is more perfect. The rise and fall of a country depends on the system. Since the new era, our party has comprehensively deepened reforms, put system construction in a more prominent position, dared to break into deep-water areas, dared to bite hard bones, and pushed forward reforms in important areas and key links. From tamping the foundation, erecting columns and beams, to all-round promotion, accumulating strength, and then to system integration, coordination and high efficiency, the basic institutional framework in various fields has been basically established, and historical changes, systematic reshaping and overall reconstruction have been realized in many fields. Socialism with Chinese characteristics’s system has become more mature and stereotyped, and the modernization level of the national governance system and governance capacity has been significantly improved. The new national system gathers all parties’ joint efforts, accumulates innovative kinetic energy, and promotes high-level science and technology to take new steps of self-reliance and self-improvement; The system of strictly administering the Party in an all-round way is scientific, standardized and efficient. The loose and soft state of administering the Party has been fundamentally reversed, and the comprehensive and strict administration of the Party has been continuously deepened … … The remarkable advantages of China’s national system and national governance system are transformed into strong governance efficiency, and the powerful system is used to overcome risk challenges and achieve great things. Institutional advantage is the greatest advantage of a country, and institutional competition is the most fundamental competition among countries. A more mature and stereotyped institutional system provides a fundamental guarantee for us to gain a firm foothold and develop in the fierce international competition. As long as we strengthen institutional self-confidence, persist in innovation, focus on giving play to and enhancing China’s institutional advantages, constantly improve and develop the Socialism with Chinese characteristics system, and promote the modernization of the national governance system and governance capacity, we can continue to "The new atmosphere of "China’s rule" continued to write a new chapter of "China’s rule".

　　Turn the grand blueprint of Chinese modernization into a beautiful reality step by step.

　　The road to simplicity is the most important thing. To persist in and develop Socialism with Chinese characteristics, we have walked through thousands of waters in Qian Shan, and we still need to wade through mountains and rivers. General Secretary of the Supreme Leader pointed out: "The new journey is an expedition full of glory and dreams. There is no shortcut, only hard work." If we want to create new great achievements with new great struggles, we must bear in mind that upholding the Party’s overall leadership is the only way to uphold and develop Socialism with Chinese characteristics, Socialism with Chinese characteristics is the only way to realize the great rejuvenation of the Chinese nation, Chinese people are the only way to create great historical achievements, implementing the new development concept is the only way for China to develop and grow in the new era, and comprehensively administering the Party strictly is the only way for the Party to keep its vitality forever and take a new road to catch the exam. We should fully implement the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, cherish and always adhere to the "Five Necessary Ways", regard the promotion of Chinese modernization as the greatest politics, unite the overwhelming majority of the people under the unified leadership of the Party, focus on the central task of economic construction and high-quality development, turn the grand blueprint of Chinese modernization into a beautiful reality step by step, and write a more splendid chapter for Socialism with Chinese characteristics in the new era.

　　Enhance confidence in winning. General Secretary of the Supreme Leader pointed out: "The people have confidence, and the country has a future and the country has strength." As long as you have confidence, loess becomes gold. We should be good at drawing wisdom, boosting confidence and increasing strength from the road we have traveled. Since the new era, under the complicated situation of the century-long changes and the century-long epidemic, Socialism with Chinese characteristics’s roads, theories, systems and cultures have been full of vitality, the great rejuvenation of the Chinese nation has entered an irreversible historical process, and the people of China have become more confident and self-reliant. Practice has proved that scientific theory is the "golden key" for us to promote our work and solve problems. The more we learn, the more confident we are, and the more powerful we learn. We should learn to understand and implement Socialism with Chinese characteristics Thought of the Supreme Leader in the new era, adhere to the integration of learning, thinking and application, and unify knowledge, belief and practice, and turn this important thought into a powerful force to strengthen ideals, temper party spirit, guide practice and promote work, consolidate and expand the educational achievements of Socialism with Chinese characteristics Thought in the new era of the Supreme Leader, and turn it into the effect of promoting high-quality development. Adhere to a comprehensive, dialectical and long-term perspective to scientifically analyze the situation, grasp the general trend of development, and firmly develop confidence. We must not only see the rapid changes in the external environment of China’s development, but also increase the number of uncertain and unpredictable factors; We must also see that China has embarked on the road of high-quality development. The development has a more perfect institutional guarantee, a more solid material foundation and a more active spiritual strength. The favorable conditions are stronger than the unfavorable factors, and the economic resilience is strong and the potential is sufficient. Wide room for manoeuvre,The long-term positive fundamentals have not changed and will not change. We are confident and more capable of achieving long-term stable development, and constantly bring new impetus and new opportunities to the world with the new development of China.

　　Always unite and struggle. Strength comes from unity, and happiness comes from struggle. Unity formed around a clear goal of struggle is the strongest unity, and struggle based on close unity is the most powerful struggle. In order to build a socialist modern country in an all-round way and comprehensively promote the great rejuvenation of the Chinese nation, we must persistently use the supreme leader’s Socialism with Chinese characteristics Thought in the new era to forge a soul, use the Party’s innovative theory to guide the correct direction of United struggle, and consolidate the common ideological foundation of United struggle. It is necessary to consolidate and strengthen the unity and unity of the Party, more consciously and profoundly understand the decisive significance of the "Two Establishments", always maintain a high degree of unity with the CPC Central Committee with the Supreme Leader as the core in ideological and political actions, conscientiously implement democratic centralism, and strictly abide by the party’s political discipline and rules. Consolidate and strengthen the unity between the party and the people, practice the people-centered development thought, promote the fruits of reform and development to benefit all the people more fairly, always want to be together with the masses, always maintain the flesh-and-blood ties between the party and the people, and unite the people around the party as widely as possible. Consolidate and strengthen the great unity of the Chinese people at home and abroad, adhere to the great unity and unity, unite all forces that can be United, mobilize all positive factors that can be mobilized, unite the struggle forces of one mind and forge ahead, and form a vivid situation of hand in hand and United struggle.

　　Keep working hard. The people of China have great dreams, and they have the great spirit of hard work and hard work to realize their great dreams. Historical achievements and changes have taken place in the cause of the party and the state in the new era, which fully proves that great achievements are made and socialism is done. Only by hard work can we prosper the country, strengthen the country and enrich the people. History will not live up to those who do it. On the new journey, we should vigorously carry forward the spirit of self-reliance and hard struggle, be aware of and brave in shouldering heavy burdens, be tenacious, bear hardships and stand hard work, work hard, be not afraid of fatigue and difficulties, and strive to create achievements that can stand the test of practice, people and history. We must implement it to the letter, resolutely implement it, be realistic and pragmatic, dare to do good deeds, and implement the decision-making and deployment of the CPC Central Committee. Start a business with the spirit of nailing, do one thing after another, do it year after year, stick to a blueprint to the end, drip through the stone for a long time, and turn the great dream into reality step by step.

　　Be brave in tenacious struggle. Dare to struggle and dare to win is an invincible and powerful spiritual force for the people of the Communist Party of China (CPC) and China. Struggle for security means safe survival, compromise means safe death; Struggle for development leads to prosperity, while compromise leads to decline. "The various struggles we face are not short-term but long-term, at least with the whole process of achieving the goal of the second century." Our party has come to this day by struggle, and it is bound to win the future by struggle. On the new journey, we must always maintain the dauntless spirit of meeting the brave in the narrow road, and the more difficult and dangerous it is, the more forward we will be, be prepared for danger in times of peace and prepare for a rainy day, and be prepared to withstand the major test of high winds, high waves and even stormy waves. We should dare to speak out against the wrong words and deeds related to political principles, to tackle all kinds of difficult contradictions in economic and social development, to cure all kinds of unhealthy practices and negative corruption within the party, and to be unswerving and courageous in all kinds of acts that discredit the image of the party and the country and harm the interests of the country and the people by hostile forces. We should strengthen our fighting skills, not only dare to struggle, dare to encounter difficulties, but also be good at struggle, stress the art of struggle, be good at grasping the main aspects of major contradictions and contradictions, grasp the overall situation, prioritize and rationally choose the way of struggle, overcome all kinds of difficulties and challenges on the road ahead with all our strength, and open up a new world of career development by tenacious struggle.

　　Take the initiative. The General Secretary of the Supreme Leader stressed: "We must persist in independence, self-reliance, the development of the country and the nation on the basis of our own strength, and firmly hold the destiny of China’s development and progress in our own hands." Only by grasping the law and general trend of historical development can we always grasp the historical initiative of the development of the cause of the party and the state. On the new journey, we should unite more closely around the CPC Central Committee with the Supreme Leader as the core, persist in observing, grasping and leading the times with the Supreme Leader’s New Era Socialism with Chinese characteristics Thought, better coordinate the overall situation of the great rejuvenation strategy of the Chinese nation and the great changes that have never happened in the world in a century, gain a profound insight into the times, the situation, the crisis and the opportunity, and actively learn to adapt to changes. Be more proactive, face up to difficulties, and perform your duties with proactive and energetic creative work. Be more proactive in coping with changes, vigorously promote reform and innovation, constantly shape new development momentum and new advantages, and fully stimulate the creative vitality of the whole society. Be more proactive in preventing and resolving risks, grasp the initiative in work and fight for development in dealing with risks. As long as we put the major decision-making arrangements made by the 20th National Congress of the Communist Party of China into action step by step, see the results, strengthen our confidence, work hard with one heart and one mind, and forge ahead courageously, we will certainly win the advantage, the initiative and the future.

　　The blueprint is inspiring, the horn is inspiring, and the journey has no end. In the face of great responsibility and glorious mission, all party comrades must remember Do not forget your initiative mind’s mission, be modest and prudent, work hard, dare to struggle, be good at fighting, strengthen historical self-confidence, enhance historical initiative, and write a more splendid chapter for Socialism with Chinese characteristics in the new era.

　　CCTV News:In recent years, China’s nuclear power technology has developed rapidly and has entered the first phalanx of nuclear power technology in the world. Recently, China Nuclear Energy Industry Association released the Blue Book of China Nuclear Energy Development Report 2024.

　　According to the blue book, up to now, there are 26 nuclear power units under construction in China, with a total installed capacity of 30.3 million kilowatts, and both the number under construction and the installed capacity remain the first in the world. The independent third-generation nuclear power technology represented by "Hualong No.1" and "Guohe No.1" is being deployed in an orderly manner in China.

　　At the same time, China has made breakthroughs in many technical directions of the fourth generation nuclear power technology. The world’s first fourth-generation nuclear power plant put into commercial operation — — The demonstration project of Shidaowan high-temperature gas-cooled reactor has generated more than 650 million kWh since it was put into operation in December 2023. This marks that China has reached the world leading level in the research and development and application of the fourth generation nuclear power technology, which is also a pioneering work of China leading the world in nuclear energy technology.

　　Fourth Generation Nuclear High Temperature Gas Cooled Reactor: A Safer Future Energy

　　What are the characteristics of the fourth generation nuclear power technology? What does "high temperature gas cooled reactor" mean? In addition to the "high temperature gas cooled reactor", what other reactor types are there in the fourth generation nuclear energy system?

　　The world’s first fourth-generation nuclear power plant has an installed capacity of 200,000 kilowatts.

　　Shidaowan High-temperature Gas-cooled Reactor Demonstration Project is located in Rongcheng City, Shandong Province. It is a landmark achievement of major national science and technology projects with completely independent intellectual property rights in China, and it is also the first fourth-generation nuclear power plant in the world. The installed capacity of the project is 200,000 kilowatts, and the power generation is enough to meet the electricity demand of 200,000 households.

　　High temperature: The reactor core is made of high temperature resistant materials.

　　High temperature gas-cooled reactor includes two key words: "high temperature" and "gas cooling". High temperature means that the core of the reactor is made of high temperature resistant materials such as graphite and ceramics, so that the core temperature can reach nearly 1000 degrees Celsius.

　　Air cooling: inert gas helium is used for core cooling and heat transfer.

　　Air cooling means that the reactor uses inert gas helium for core cooling and heat transfer, which is different from the "water cooling" mode of traditional nuclear power plants. Helium is not easy to react with other substances in the reactor at high temperature, so it is called high temperature gas cooled reactor.

　　Zhang Zuoyi, chief designer of the high-temperature gas-cooled reactor nuclear power plant, a major national science and technology project, introduced that in 2023, this reactor was used for a very important safety verification test. After stopping the whole external output energy system, the reactor was able to "brake" itself and slowly cool down, which scientifically proved the "inherent safety" of the reactor.

　　BEIJING, July 14 (Xinhua) Ruan Jianhong, spokesman of the People’s Bank of China and director of the Survey and Statistics Department, said on the 14th that in the first half of the year, various loans of financial institutions increased by 15.73 trillion yuan, an increase of 2.02 trillion yuan over the same period of last year, indicating that the financial system has further increased its support for the real economy. From the perspective of industry investment, new loans were mainly invested in key areas such as manufacturing and infrastructure, and the growth of loans in the real estate industry also showed a sustained recovery trend, and the structure of the loan industry was further optimized.

　　Ruan Jianhong said that from the perspective of loan subjects, loans from enterprises (institutions) were the main body of loan increment in the first half of the year. In the first half of the year, loans from enterprises and institutions increased by 12.81 trillion yuan, an increase of 1.42 trillion yuan year-on-year, accounting for 81.5% of the total credit increase. Household loans increased by 2.80 trillion yuan, an increase of 572.3 billion yuan. The main reason for the increase in household loans is the increase in personal business loans and short-term consumer loans. In the first half of the year, personal business loans increased by 2.3 trillion yuan, an increase of 759.3 billion yuan over the same period of last year; Personal short-term consumer loans increased by 300.9 billion yuan, an increase of 401.9 billion yuan.

　　From the perspective of industry investment, new loans were mainly invested in key areas such as manufacturing and infrastructure, and the growth of loans in the real estate industry also showed a sustained recovery trend, and the structure of the loan industry was further optimized. Specifically:

　　The growth rate of medium and long-term loans in manufacturing industry maintained a high level. At the end of June, the medium and long-term loans of manufacturing industry increased by 40.3% year-on-year, 10.7 percentage points higher than the same period of last year, and 22.3 percentage points higher than the growth rate of medium and long-term loans of all industries. In the first half of the year, loans increased by 2.15 trillion yuan, an increase of 821.9 billion yuan year-on-year. Among them, the medium and long-term loans of high-tech manufacturing industry increased by 41.5% year-on-year, 11.5 percentage points higher than the same period of the first half of the year. In the first half of the year, the medium and long-term loans for new high-tech manufacturing industries were 483.5 billion yuan, an increase of 184.7 billion yuan year-on-year.

　　Look at the infrastructure industry. Medium-and long-term loans in the infrastructure industry grew rapidly. At the end of June, medium and long-term loans in infrastructure industry increased by 15.8% year-on-year, 3.3 percentage points higher than the same period of last year. In the first half of the year, it increased by 3.25 trillion yuan, an increase of 1.1 trillion yuan over the same period of last year.

　　The growth rate of medium and long-term loans in the real estate industry continued to rise. At the end of June, the medium and long-term loans in the real estate industry increased by 7.1%, 0.2 and 8.5 percentage points higher than the end of last month and the same period of last year respectively, and the growth rate has been rising for 11 consecutive months. In the first half of the year, the real estate industry added 628.7 billion yuan in medium and long-term loans, an increase of 459 billion yuan year-on-year.

　　Ruan Jianhong pointed out that in the next step, the People’s Bank of China will continue to give full play to the dual functions of monetary policy tools, maintain a reasonable growth of credit and a stable pace, and continue to increase support for key areas and weak links of the national economy to help the real economy to further improve.

　　Beijing, August 14, 2005 According to the report of China Voice "National News Network" of the Central Radio and Television General Station, on August 15, 2005, when the then supreme leader of Zhejiang Provincial Party Committee visited Yucun, Anji County, Huzhou City, Zhejiang Province, he first proposed "Lucid waters and lush mountains are invaluable assets". Nowadays, the concept of "Lucid waters and lush mountains are invaluable assets" has become the consensus and action of the whole party and society, and has become an important part of the new development concept. Since the 18th National Congress of the Communist Party of China, under the guidance of the concept of "Lucid waters and lush mountains are invaluable assets", all localities have actively practiced the ecological civilization thought of the supreme leader, adhered to ecological priority and green development, made great efforts to solve outstanding environmental problems, strengthened the protection of ecosystems, and continued to write a new chapter in the concept of "two mountains" in continuous practice.

　　In September 2013, when the Supreme Leader answered students’ questions at Nazarbayev University, he explained the concept of "Lucid waters and lush mountains are invaluable assets": "We want green mountains and green hills, but also Jinshan Yinshan. I would rather have green mountains and green hills than Jinshan Yinshan, and Lucid waters and lush mountains are invaluable assets. "

　　The concept of "Lucid waters and lush mountains are invaluable assets" gives consideration to economy and ecology, development and protection, and provides important guidance for adhering to green development and building beautiful China in the new era.

　　Do not exchange temporary economic growth at the expense of the environment, and do not take the old road of "pollution first, then treatment". In Xilin Gol League, Inner Mongolia, more than 60% of the area in the League has been designated as the red line of ecological protection, and no new mine development projects will be built on the grassland. By June 25th, 67 industrial and mining enterprises in six national nature reserves in Xilin Gol League had all closed down. Ma Weiguo, deputy director of the Natural Resources Bureau of Xilin Gol League, said: "According to ‘ If you are green, you will survive; if you are not green, you will retreat ’ It is required that by the end of 2023, all our production mines will meet the standards of green mines. "

　　Since the 18th National Congress of the Communist Party of China, a number of systems, such as evaluation and assessment of ecological civilization construction objectives and accountability for ecological environmental damage, have been promulgated and implemented. The central eco-environmental protection inspector started the pilot project in 2015, and by 2018, it has achieved full coverage of routine inspectors in 31 provinces (autonomous regions and municipalities) and Xinjiang Production and Construction Corps, and the role of the inspector’s sword has been effectively played.

　　At the same time, in view of the ecological and environmental problems accumulated in China’s rapid development over the years, ecological restoration has been placed in a more prominent position in various places. In order to protect the ecological environment of the Yangtze River, from January 1 this year, 332 nature reserves and aquatic germplasm conservation zone in the Yangtze River basin were completely banned from productive fishing. The main stream of the Yangtze River, important tributaries and large Tongjiang lakes will be temporarily banned for 10 years from 0: 00 on January 1, 2021 at the latest.

　　As the province with the longest mileage flowing through the main stream of the Yangtze River, Hubei has set up a file for all the more than 26,000 fishermen who have retired in the province to ensure the implementation of the no-fishing measures. Since July 1st this year, the Yangtze River has been closed to fishing for ten years in Jingzhou City. Bie Shaobo, deputy secretary and deputy director of the Party Group of Jingzhou Agricultural and Rural Bureau, said: "The most important thing is to accurately set up files for these fishermen and transfer them to jobs for training, so that they can be reborn. We are determined to use the greatest strength and the most powerful measures to advance this work and achieve the goal we should achieve as soon as possible. "

　　In the comprehensive experimental zone of marine ecological civilization of Long Island in Yantai, Shandong Province, the coastline ecology of Long Island has been gradually restored through measures such as vacating coastal aquaculture. At the same time, four state-level marine pastures and six provincial-level marine pastures will be built in Long Island, and the construction of marine pastures will create a "green water and green mountains" at sea, leading the marine fishery from the nearshore to the deep blue. Li Junjie, the full-time deputy secretary of the Working Committee of the Long Island Marine Ecological Civilization Comprehensive Experimental Zone, said: "People have to be compensated for their investment in these areas. In addition, we should consider their changing jobs. What ordinary people used to raise seedlings led to the tourism industry and the cultivation of offshore seafood. We must protect the fruits of our ecological restoration and let the people feel happy living in Long Island. "

　　In recent years, Fuxin City, Liaoning Province, the first pilot city for economic transformation of resource-exhausted cities in China, has developed 12 theme racetracks of various types by using abandoned pits. The green development model of "ecological restoration+industry" makes the "urban scar" of Baili realize a gorgeous turn from black to green. From the end of 2018 to 2019, the newly-built Centennial International Circuit City has held six cross-country events and received more than 200,000 visitors. The bustling crowd has also brought a good life and new hope to the local people. Mr. Ma, a citizen, said: "The Gangzi Mountain in the past has now become an ecological park, with birds and flowers. The construction speed of the track city is particularly fast, and the surrounding facilities such as greening and roads are very good, as well as container hotels, which are fashionable and modern and more and more international. "

　　Environment is people’s livelihood, green hills are beautiful, and blue sky is also happiness. Holding the green mountains and green hills, not only Jinshan Yinshan is harvested, but also the people’s hearts are full of sense of gain and happiness.

　　In Chengdu, Sichuan, Tianfu Greenway, which has been built for more than 3,689 kilometers, has become the most inclusive livelihood project in the park city; In Hebi, Henan Province, the Qihe River scenic belt with a total length of about 6 kilometers has become a good place for citizens to relax; In Lanzhou, Gansu Province, the local government combined the Yellow River management with the improvement of people’s happiness index to create various landscape belts along the Yellow River. Chen Yifu, director of Lanzhou Natural Resources Bureau, said: "Increase public service facilities, make the Yellow River a happy river for the people, and build Lanzhou into a demonstration area for the high-quality development of the Yellow River and a pioneering area for ecological protection."

　　In Zhongliao Village, a Li village in the north of Sanya, Hainan, the once unknown Zhongliao Village "Butterfly Change" is a well-known "star" village in Hainan. The villagers have a "tourist meal" at their doorstep and sing a happy song of the Liao people in the new era.

　　At present, the national forest area has reached 220 million hectares, and the forest coverage rate is 22.96%. In the past 20 years, the new vegetation coverage area ranks first in the world. The number of cities with national air quality standards increased from 73 in 2015 to 157 in 2019. With the solid progress of ecological civilization construction, a beautiful new picture of China is slowly unfolding.

Do you know how popular real sales experts are?

Let’s look at a data:Among the top 500 CEOs, the most are from sales, and the second most are from finance, which add up to more than 95%.

This was mentioned by the former HP global vice president in his retirement speech.

Sales, a seemingly low-threshold occupation, is related to the lifeline of enterprises.

In today’s situation, the sales war determines whether the enterprise can outperform the opponent in difficult times.

But what will the top sales elite do?

Sales is a job that tests people’s mentality. It requires a strong heart, and you may be rejected and even humiliated by customers again and again. If you can still adjust your mentality and bite the bullet and catch up, it will be really great.

Most new sales start from the most basic work, and need to call and send WeChat again and again to find target customers. It is very unpleasant to be rejected mercilessly and hung up, and most sales have to experience countless rejections a day.

You used to think that those low-threshold sales that accompany wine have no gold content, but in fact they don’t have the thick skin and the spirit of repeated defeats and wars. Most people can’t even do low-threshold sales, and it is easy to be attacked and doubt their lives.

When you finally establish contact with customers, but only remain polite and unfamiliar, then you should also be careful.

Because sales experts know that the key to door-to-door sales is to become friends with customers and become one with them. If the customer is polite to you, it means that you haven’t entered the customer’s heart. This kind of customer relationship is very fragile. Once the master salesman of the competitor sells, the customer will easily fall to the competitor.

Therefore, there is an old saying in the marketing field called:"Be friends first, then do business."

Quotations from sales experts:

The most economical and effective way to open the other person’s heart is to praise your customers. But remember: Flattering "flattery" indiscriminately and untimely will only embarrass your customers.

It’s often seen that new salespeople desperately introduce products and enterprises to customers when they meet them for the first time. I wonder if customers are not familiar with you, and it’s already a face for you not to kick you out. Will he still listen to your introduction carefully?

We should disguise ourselves as his peers or higher in front of customers! Only in this way can customers respect you and recognize you, and then they will discuss their work with you.

4 Don’t expect to get the customer right away when you visit for the first time. At most, you should throw stones to ask for directions. The main purpose is to get to know the internal situation by contacting the customer, such as who can make the decision and which relationships need to be dealt with …

The law of sales is: communicate well with the people above, and communicate poorly with the people below, and there is a 20% chance of being turned over; Communicate well with the people below, and if you don’t communicate well with the people above, there is a possibility that 80% will be turned over! Therefore, every link is guaranteed to be safe, and that is really safe.

Sales experts will definitely find out the personnel structure of the other company before winning the big order, and find out who is the recommender, the influencer and the decider.

The recommender is often the person in charge of the purchasing department or technical department of the other company, who is the best to know and buy, and he can push our list to the person who has the final say. The influencer is a person who is one level higher than the recommender and can turn a deaf ear to the finalization of cooperation.

In large-scale projects, it is of little value to just get rid of one person. If the recommender doesn’t recommend you, the decider won’t dare to decide you, because there are too many risks. If the recommender recommends you and the influencer attacks your weakness, the decider will not dare to decide you. If the recommender recommends you, the influencer has no opinion, and the decider has not been settled, the variables are also very large.

Persuade "Wang" with the help of "Wizards" (that is, technology); Persuading "scholars" depends on interests.

In other words, it is to convince people at the level of boss and boss that you are not qualified to talk about technology and money, and others will not care about you; Persuade middle-level cadres who work, you want to talk about benefits, you talk about technology, others will say yes on the surface, but in fact, they are eager for you to get out of here early.

In particular, we should remember that we should protect our related parties and references, try to pretend that we don’t know him in the office, or at least show that we are unfamiliar with him. Otherwise, customers will see that one side of the company has stood with the salesman, and the gold content of the referee’s speech will be greatly reduced.

Quotations from sales experts:

Any salesman is not facing the customer’s company, but the customer’s individual.

The premise of getting the key person is: 1) you should be good at appraisers; 2) you should be sensitive; 3) you should be able to close the distance with customers; to have this ability, you must 1) run more customers; 2) you should be good at summarizing.

3 winning small customers depends on being a man, because small customers don’t have much conflict of interest, winning big customers depends on methods and strategies, because big customers have huge interests, and human nature is worthless before interests.

Don’t imagine that you can win the contract by talking about technology with others.

A clever salesman understands that the overall goal of "signing the bill" is decomposed into eight small goals that can be achieved and have continuity:

Goal 1: collect customer information;

Goal 2: contact customers;

Goal three: let customers have a good impression on me (giving small gifts or promising benefits);

Goal four: let customers know about our products that best match their needs (repeated promotion of technical selling points);

Goal five: get the approval of the customer’s decision maker and key people (business activities);

Goal 6: Understand and meet the procurement procedures;

Goal 7: Participate in bidding;

Goal 8: Winning the bid.

Concentrate on conquering key targets at each stage, and finally sign big orders.

If you want to make a big order, you must first remember."28 rule"：

Customers who do not have enough conditions to buy or always want to get low prices are called inaccurate customers, and they should be deleted as much as possible. Because they can only create 20% performance for you, but they often consume 80% of your time and energy.

Secondly, the sales idea should be changed from "I want to sell" to "customers buy with me".

Finally, make your product complicated and important.

How to complicate an extremely simple product and raise it to a high price can be based on the analysis of consumers’ buying behavior, starting from the following aspects:

① Linking products with highly complicated problems;

(2) establish the image of Smith;

③ Understand the real concerns of customers and put forward their own solutions;

④ Make the differentiation of their products more obvious.

So as to establish a high-value brand image in the hearts of customers and win high-priced orders.

Quotations from sales experts:

It’s foolish to keep repeating the wrong sales method. You should be good at summarizing why it is not accepted by customers, so that you can make progress.

Solving problems is first of all strategic, grasping the laws, then technical, and finally psychological and detailed.

The key to the mid-term sales is differentiation. Differentiation gives you a label to make you look different, attract customers’ attention and interest, which must be marked and done in the middle of the specific documentary process. Only in this way will customers pay more attention to you.

As long as you are enthusiastic about life, enthusiastic about people, know how to read and feel, make people feel good about you quietly, know the way of the world, know how to predict the development trend of things, and then work hard, then there will be a wonderful story.

Click on the blue word above to pay attention to "vitality and harmony"

College entrance examination is a big test in the life of college students, which is related to the vital interests of candidates and has attracted much attention from the society. The college entrance examination in 2024 is approaching, and the majority of candidates are actively adjusting their status and preparing for the exam calmly and orderly. However, some lawless elements are driven by economic interests to spread false information about the exam, sell and create anxiety, and even commit fraud and induce candidates to cheat in the exam, which seriously disrupts the enrollment order of the exam. To this end, the Ministry of Education, in conjunction with relevant departments, has sorted out some typical cases that have appeared in recent years, and solemnly reminded the majority of candidates and parents that they must be vigilant, beware of being deceived, and do the integrity test. Let’s look at it together-

First, organizing cheating in the college entrance examination can’t escape the recovery of the French Open.

[Case] Before the college entrance examination in 2023, some criminals promised candidates through QQ group and other channels that they would pass the answers to the candidates during the college entrance examination. Candidates only need to bring in electronic devices and send back the questions. The Ministry of Education, the Ministry of Public Security and other relevant departments jointly conducted rapid investigation and successfully destroyed relevant criminal gangs before the exam.

【 Regulations 】 The Criminal Law of People’s Republic of China (PRC) clearly stipulates that it is illegal to "organize cheating" and "provide examination questions and answers to candidates" in the national examinations prescribed by law. The Interpretation of the Supreme People’s Court and the Supreme People’s Procuratorate on Several Issues Concerning the Application of Laws in Handling Criminal Cases, such as Cheating in Organizing Examinations, makes it clear that those who organize cheating in national education examinations, such as college entrance examinations and postgraduate entrance examinations, shall be deemed as "serious" acts, and shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years and fined.

[Reminder] In recent years, local public security organs, together with the education departments, have continued to maintain a high-pressure and severe crackdown on all kinds of illegal and criminal activities involving exams. Remind the majority of candidates that they must enhance their legal awareness, know the law and abide by it, and don’t be confused for a while and regret it for life.

Second, "Gui Li" will eventually become "likui jy", and it is not feasible to challenge the law.

[Case] In the unified entrance examination of art and design major in colleges and universities in a province in 2020, two "exam-assisting" intermediaries found a college student to take the test for a candidate and were arrested by the police. Two cheaters were sentenced to three years and eight months in prison and three years and two months in prison respectively. Taking the test for college students was sentenced to five months’ criminal detention and suspended for one year.

【 Regulations 】 The Criminal Law of People’s Republic of China (PRC) clearly stipulates that it is illegal to "organize cheating" or "substitute others or let others take the exam instead of themselves" in the national examination prescribed by law.

[Reminder] In recent years, some new technical means have been gradually used in the management of national education examinations to prevent fraud such as taking exams. Although the results of college entrance examination are important, the quality of honesty is related to the development of a person’s life. Don’t believe in the temptation of criminals, and don’t be lucky enough to take the exam for others or let others take their place. Trying the law will eventually "eat the consequences".

Third, avoid the security belt "equipment", and the attempted cheating will ruin the future.

[Case] During the college entrance examination in 2022, a candidate avoided the entrance security check and illegally brought his mobile phone into the examination room. After the examination, he took a test paper and sent it to QQ group for an answer, which was unsuccessful, and was seized by the public security organs at the first time according to law. According to relevant regulations, candidates who violate the rules are dealt with seriously.

[Regulations] The college entrance examination is a national education examination prescribed by law. The Measures for Handling Violation of National Education Examination clearly stipulates that anyone who carries equipment with the function of sending or receiving information should be considered cheating in the examination, and the scores of all stages and subjects he signed up for the examination are invalid. The Education Law of the People’s Republic of China clearly stipulates that candidates who carry or use cheating equipment and materials in national education examinations, if the circumstances are serious, shall be ordered by the education administrative department to stop taking the relevant national education examinations for more than one year and less than three years; If it constitutes a violation of public security administration, it shall be punished by the public security organ according to law; If a crime is constituted, criminal responsibility shall be investigated according to law.

[Reminder] In recent years, the Ministry of Education, together with relevant departments, has deployed a special treatment for cheating on mobile phones in the college entrance examination, and resolutely prevented cheating on high-tech equipment such as mobile phones by strengthening the entrance clearance and invigilation clearance. During the examination, all candidates take the examination in the standardized examination room and under the whole video surveillance; After the exam, the video of the examination room will also be played back and reviewed. Candidates should consciously abide by the requirements of the rules of the examination room, obey the management of the examiners, refuse to carry illegal and prohibited items such as mobile phones, and abide by the examination discipline. Losing an exam is not important, but losing your life is not worth the loss.

Fourth, spending money to walk is not credible, and there is no "pie" with "trap"

[Case] Parents in a province received a short message from an unknown number, and then they received a message from their "daughter" who lived in the school, saying that they wanted to sign up for a training course offered by a well-known university. Parents are eager to love their daughters and have established contact with a "teacher Zhang" who is in charge of training matters. "Teacher Zhang" said that paying 300,000 yuan can "walk" to this prestigious school. Later, the "daughter" and "teacher Zhang" attacked each other and urged the payment for various reasons, defrauding a total of 180,000 yuan.

[Reminder] There is a strict workflow for college admissions. There is no such thing as "internal enrollment" and "paying for admission" in the process of college entrance examination. Candidates and parents should be highly alert to such deception under the guise of "spending money to buy university places" and "special channel admission". It is necessary to understand and confirm the examination enrollment policies and information from formal channels. False propaganda for some bad training institutions and criminals. Candidates and parents should not be credulous and deluded, so that they are deceived, causing property losses and delaying valuable review time.

Fifth, the college entrance examination volunteers have been tampered with, and information disclosure needs to be vigilant.

[Case] A candidate in a province illegally tampered with the college entrance examination volunteer by using his classmate’s admission ticket number because of his bad relationship with his classmates, which caused his classmates to be affected. The public security organ imposed a five-day administrative detention on the candidate, and the Provincial Admissions Office decided to let the victim re-fill in his volunteers to maintain the fairness and justice of the college entrance examination.

[Reminder] The college entrance examination is an important exam for candidates’ lives, and it is very important to protect the security of personal information. Candidates should carefully keep important information such as personal admission ticket number and login password, always be vigilant, avoid personal information from being leaked to others, and prevent criminals from illegally using information and infringing on personal rights and interests.

Sixth, "Zhankeng Post" is a gimmick, and the "prank" involved in the test cannot be touched.

[Case] After the math subject examination of the college entrance examination in 2023, some counseling institutions and some netizens released some pictures of the test papers, claiming to be "the test questions before the exam" and being suspected of leaking the test questions. After investigation by the public security organs, it was found that it was a malicious editor who "occupied the post". Before the exam, it posted irrelevant posts on the relevant platforms, and then replaced the original content with the content of the test paper after the exam. The post time was still displayed before the exam, which caused the illusion that it was suspected that the questions were leaked before the exam.

[Reminder] Lawyers and experts remind that if candidates maliciously publish such information, they will be suspected of breaking the law in addition to violating the examination discipline, and if the circumstances are serious, it will constitute a crime. If a training institution or other personnel, for the purpose of illegal possession, fictitiously obtains the information of test questions or "real questions" before the exam by publishing "posts occupying pits" to defraud a large amount of public and private property, it is suspected of fraud. Candidates should not "fool" themselves in order to entertain others.

Kind reminders from iPhone users always make people feel warm:

So I backhand to a "thank you":

It doesn’t matter if the iPhone’s AirDrop is used up. Not only is it a trivial matter of being harassed, but hackers can also intercept personal information in a few milliseconds.

It’s basically equivalent to making your mobile phone number, email address and other contact information public.

Moreover, this bug has long been known by Apple, but it has not been fixed.

There was no time to flash, and the information was leaked.

What’s going on?

Researchers at Darmstadt University of Technology have conducted in-depth research on loopholes, and their conclusion is:

Apple AirDrop has a two-way vulnerability. No matter whether it is accepted or sent, as long as it is opened, hackers can crack the user’s mailbox, phone number and other information in a few milliseconds.

Personal information intercepted by hackers may be used for precision phishing attacks, fraud, etc. The simplest way is to resell personal information directly for profit.

AirDrop, the name that domestic users are more familiar with, is airdrop, which is transmitted through Bluetooth and wifi. Among them, Bluetooth "handshakes" and Wi-Fi "transmits".

The whole transmission process does not require the participation of public network connections.

But the problem lies in the "handshake phase" of Bluetooth.

In the transmission confirmation stage, in order to determine whether the equipment of the possible sender should be connected with other nearby equipment, AirDrop will broadcast the local Bluetooth signal, which contains the partial encrypted hash value of the sender’s phone number and email address.

If there is a hash value that matches someone’s information in the address book of the receiving device, the two devices will shake hands for mutual authentication through Wi-Fi.

Of course, if the recipient is set to receive from any device, the address book verification can be skipped.

During the handshake, the device will exchange the complete SHA-256 hash value of the owner’s phone number and email address.

Originally, the original information that generated them cannot be directly transcribed from the hash value, but it may be calculated according to the entropy or the number of random values in the plaintext.

Therefore, in theory, hackers can do this by carrying out "violent attacks", that is, throwing out a large number of test values and "bumping" out the correct information.

The key point is that in a phone number or an e-mail address, the information entropy is negligible.

Even a database containing all possible phone numbers in the world. It only takes a few milliseconds to find a hash value in it.

That’s it. It was too late to flash, and the information leaked out.

Hackers "wait for the rabbit"

In the simplest way, hackers only need to monitor the discovery requests sent by other nearby devices without any prior information.

For example, just install a Bluetooth "bug" in public places.

The second method is the reverse.

The attacker opens the sharing menu to see if there is a nearby device responding to his handshake request message.

But this technology is not as widely applicable as the first method, because it only works when the attacker’s information is already in the receiver’s address book.

However, attacks from "acquaintances" are equally terrible.

For example, the company boss can use it to get the non-work phone number or email address of any employee.

For two years, Apple turned a deaf ear.

Does Apple know?

Of course I know. Besides, I knew it two years ago.

Not only do I know, the team of Darmstadt University of Technology, which discovered the vulnerability, has also specially developed a vulnerability patch PrivateDrop, which allows both parties to shake hands with each other without exposing the hash value.

When the vulnerability was reported in 2019, the patch was submitted together.

But two years later, the stone sank into the sea.

Apple officials have never responded to whether the researchers adopted their scheme, and the loopholes have never been fixed.

Ready-made answers are too lazy to copy …

So until today, as long as there are users who use airdrop delivery, there is a risk of revealing personal information.

At present, the only way to prevent leakage is to set AirDrop to "no one" in the system settings menu.

The launch of iOS 14.5 was originally known for its security, but now it has been exposed that serious vulnerabilities have lasted for two years and affected 1.5 billion users around the world.

By the way, I would also like to remind you that not only iOS, macOS and iPadOS on the iPhone, but also all Apple devices with the function of "air drop delivery" are under threat.
