　　　　On February 8, several journalists watched the live broadcast of Russian President Vladimir Putin’s speech at the meeting of the State Council in the Kremlin in Moscow, Russia. On the same day, Russian President Vladimir Putin delivered a speech at the meeting of the State Council, summing up his achievements in eight years in power. Russia will hold a new presidential election on March 2. Xinhua News Agency reporter Shen Bohan photo

　　　　On February 8, Putin delivered a 49-minute speech at the enlarged meeting of the Russian State Council, reviewing the achievements he has made since he came to power in 2000 and describing Russia’s development strategy before 2020. You carefully counted the digital information contained in Putin’s speech: in the 49-minute speech, Putin said 392 sentences, totaling 5210 words. In the whole speech interrupted by 19 applause, Putin mentioned "Russia" 69 times, the word "we should" 52 times, the word "publication" 50 times, the word "economy" 45 times and the word "future" 22 times.

　　　　There are less than 20 days left before the Russian presidential election on March 2, and less than three months left before the inauguration ceremony of the new Russian president in early May-the term of Russian President Vladimir Putin is entering the countdown stage. Putin chose this opportunity to make a speech. Some people say that this is Putin’s "political will" before leaving office, and it is Putin’s "homework" for his successor Medvedev. It is also claimed that this is the "campaign platform" for Putin’s return to the Kremlin in 2012, and it clearly and comprehensively explained to the Russian people what is the "Putin Plan" for the first time. More people believe that this is Putin’s "blueprint for the future" and "beautiful vision" outlined for the people as Russia’s "national leader".

　　Double GDP and become an economic power.

　　　　Putin made it clear that Russia is expected to double its GDP by the end of 2009. He said: "After the economic collapse in the 1990s, we have recovered our vitality. From 2000 to 2007, the gross domestic product increased by 72%. As long as the average annual growth rate of 7.8% is maintained, this goal can be achieved before the end of next year. " Putin put forward a "more ambitious goal" for the Russian government and people, that is, to achieve "essential changes in national life, the country and the economic and social fields."

　　　　Putin stressed that Russia has all the necessary prerequisites to achieve the above goals-"hardworking and well-educated citizens have the confidence to strive for the first place at all times. In the national character of Russians, striving for the first place has become a habit, and freedom and independence are natural", "rich natural resources and strong scientific and technological potential" and "there is no major reason to prevent us from achieving the set goals". Putin said that only with the solidarity and joint efforts of the whole society can the country’s development strategy before 2020 be realized. He said that in order for Russia to enter the ranks of world economic powers, it is necessary to create equal opportunities for all people in economic life, establish innovative development mechanisms, and promote economic development by improving labor productivity.

　　Improve the status of the army and increase its income.

　　　　When talking about security and national defense, Putin said that Russia needs to formulate a new security strategy according to threats, and the development strategy of the Russian armed forces before 2020 will be devoted to building an "innovative army." He said that in order to strengthen national defense, the Russian armed forces need to formulate a development strategy before 2020 from the threats and challenges existing in today’s world. He said that the new round of arms race and increasing military and political threats in the world forced Russia to take corresponding measures to safeguard national security. The wide application of high technology forces Russia to rethink the development strategy of the army, and scientific research achievements in the fields of biology, nanotechnology and information technology will bring revolutionary development to the army building. Putin pointed out that Russia will put into production a batch of new weapons and equipment in the next few years, and the use and maintenance of a new generation of weapons can only be completed by an army that meets the requirements of modernization. Therefore, Russia needs an "innovative army." To this end, Russia needs to greatly improve the status of the military, further increase the income of military personnel and improve their social security.

　　Increase the life expectancy and expand the middle class.

　　　　When talking about the population problem, Putin said mercilessly: "Today, half of the male citizens in our country will not live to 60 years old, which is simply a shame!" He proposed to increase the average life expectancy of Russian citizens to 75 years by 2020. When talking about the income level of residents, Putin said: "In 2020, the overall proportion of the middle class among our residents should be no less than 60% to 70%."

　　　　Regarding Putin’s speech, Russian First Deputy Prime Minister Ivanov believed that it was a summary of all the development programs of the country, and it clearly revealed the current situation of the country. Rossel, the governor of Sverdlovsk region, Russia, thinks that the president’s speech is "actually a State of the Union address and a message to the people", "Putin has accomplished many things in eight years, which is incredible, and the Russians recognize and support his reform", "I fully support his regional policy, which should become more flexible and all major powers should be transferred to local governments".

　　　　Tuleyev, governor of Kemerovo, said that Putin’s speech attributed everything to human factors and mentioned the well-being and interests of citizens, which he thought was "completely correct". Zyazikov, President of Ingushetia, stressed that Putin pointed out the strategic areas of national development in the next few decades. "Since the disintegration of the Soviet Union, we have never had such a powerful, global and systematic national development plan", and Russia has formulated an "ambitious, concrete and realistic plan". He believes that Russia has promulgated the Development Strategy before 2020, which shows that the country has achieved political and economic stability and won the trust of investors.

　　[car home New Energy] In the eyes of enthusiasts and technology controllers, the new energy vehicle is more like a work of art, and every core component is its essence. When talking about pure electric vehicles, they will ask you about battery manufacturers or battery suppliers, which can be regarded as the second brand of vehicles; When it comes to hybrid cars, they will ask you "P". What do these slang words mean? Today, I will talk to you about different types of motor architectures for hybrid vehicles.

　　At present, the application modes of motor architecture in the industry are different, and the specific applications and explanations under different architectures are also slightly different. The starting point of this paper is to sort out the basic principles and application modes of p0-p4 architecture and the purpose of different combination schemes.

● Definition and analysis of P0-P4 motor

　　In hybrid electric vehicles, it can be divided into P0-P4 and Ps architectures according to the different motor Positions, where P stands for motor position, and the motors in different positions play different roles, which are directly related to vehicle energy consumption and power performance. Which hybrid electric vehicle is more suitable for you?

◆P0 architecture: simple structure and early fame.　

　　The motor with P0 structure is installed at the front end of the engine, which is connected with the crankshaft of the engine through a belt. The vehicle equipped with P0 motor can drive the mechanical compressor of the air conditioner to run when the engine stops at the traffic lights, so as to realize engine start and stop, braking energy recovery and power generation, and auxiliary power output.

"Bosch 48V MHEV System"

　　The technology and structure of P0 architecture are relatively simple and widely used. The automatic start-stop system that many drivers and friends shut down when they get on the bus is a typical P0 architecture, and the history of automatic start-stop can be traced back to 1970s. Compared with vehicles equipped with automatic start-stop function, P0 architecture adopts BSG (belt-driven starter/generator; Belt-driven starter/generator) motor, and equipped with a larger battery, can be competent to drive the compressor and auxiliary engine.

　　When the engine is stopped, P0 motor can drive the air conditioner compressor to work independently, thus reducing the idle time of the engine; When the vehicle starts or accelerates, P0 motor can assist the engine to run, help the engine quickly get rid of the inefficient working range, save fuel and effectively improve the driving quality. Because P0 motor transmits power to the wheels in series, the motor can’t drive the wheels independently without the engine, so there is no pure electric driving mode. In addition, the P0 motor is flexibly connected with the crankshaft through a belt, so the ceiling for applying force to the engine and recovering kinetic energy power is low.

"2020 modified Mazda CX-5 2.5L automatic four-wheel drive smart model"

　　Audi SQ7 TDI and Mazda i-Eloop belong to P0 architecture. Because P0 architecture has low transmission efficiency and the motor can’t directly drive the wheels, P0 motor usually appears as an auxiliary in the field of new energy vehicles. There will be corresponding analysis and cases in the following.

◆P1 architecture: independently developed/highly integrated.

　　P1-based motor is located at the rear end of the engine crankshaft, which replaces the traditional flywheel. Besides inheriting the function of flywheel to store energy and inertia outside the engine power stroke, P1-based motor has similar functions as P0-based motor, and also supports engine start and stop, braking energy recovery and power generation, and auxiliary power output.

Honda IMA hybrid system

　　Compared with P0 architecture, P1 architecture is more compact, and its motor is integrated in the engine housing. The design needs to consider the volume of the engine and the layout in the engine room. Because different gearboxes need corresponding design schemes, the research and development and manufacturing costs of P1 motor are relatively high. Existence is reasonable, and high investment often corresponds to high return. The engine crankshaft acts as the rotor of P1 motor, which has higher power transmission efficiency, better fuel saving effect and more obvious improvement on driving performance. In addition, P1 motor can apply auxiliary braking torque through electromagnetic field adjustment on downhill section to improve safety.

　　Although they are in different positions, P0 and P1 are connected with the same disease. As long as the motor rotates, the engine crankshaft must rotate, so the motor can’t drive the wheels alone, and there is no pure electric driving mode. In the kinetic energy recovery and sliding mode, the kinetic energy is wasted because the crankshaft must be driven to idle, and the noise and vibration are also increased because of the internal combustion engine following.

"Mercedes M254 Engine"

"2020 Mercedes-Benz E-Class (imported)"

　　A few days ago, the E350 model launched by Mercedes-Benz overseas adopted a 2.0T 4-cylinder engine code-named M254, and added 48V light mixing technology in the electrification transformation process. The ISG motor equipped with it has a maximum power of 12kW and a peak torque of 180N·m, which alleviates the performance of turbine lag when the wheels start and accelerate. This system is a typical P1 architecture. Officially, the motor is named "FAME" (modular engine). Some foreign media have speculated that this motor will appear on other PHEV models.

◆P2 architecture: modular design/strong fuel economy and wide application.　

　　The P2-frame motor is located between the engine and the gearbox. Because it is not necessary to be integrated in the engine housing like P1 motor, the layout can be more flexible. The structure can be equipped with 1-2 clutches between the engine and the gearbox, which can be divided into three layout modes: ① Single-clutch structure in which the motor is arranged in front of the clutch, and the motor plays the role of assisting, parking power generation and starting the engine, which is similar to P1 structure; (2) Single-clutch structure in which the motor is arranged behind the clutch, so that the motor can drive the vehicle independently, recover braking energy, generate electricity and assist; ③ The motor is arranged in the middle of the dual clutch structure, so that the motor can drive the vehicle independently, and can also start the engine or park for power generation.

　　P2 architecture has strong compatibility and can be matched with all gearboxes (including manual gearboxes). P2 architecture is widely used in hybrid vehicles at present, and many parts suppliers have mature solutions. Take Borgwarner’s P2 motor module as an example. It integrates a dual-mass flywheel and an engine release clutch, which can disconnect the clutch and the motor direct-drive vehicle. It can convert an internal combustion engine-powered vehicle into a hybrid vehicle without changing the engine and gearbox, which means that car companies can expand the power combination of vehicles and enrich the product line of hybrid vehicles with less investment, shorter time and greater flexibility.

"Audi A3 e-tron Power System"

"2017 Audi A3 new energy (imported) Sportback e-tron comfort type"

　　Audi A3 e-tron is a representative model with P2 architecture. It is equipped with a 1.4T engine and a permanent magnet synchronous motor with a maximum power of 75kW. The battery capacity of the car is 8.8kWh, and the pure electric cruising range is 50km under NEDC condition.

◆P3 architecture: efficient power transmission and large space occupation.　

　　The P3-frame motor is located at the output end of the gearbox, and its pure electric drive and kinetic energy recovery efficiency are high, and the effect of rapid acceleration is very direct. In terms of function, P3 motor can realize braking energy recovery and pure electric drive vehicles. Because the motor can’t be integrated with the gearbox or engine, it needs to occupy extra volume, so P3 architecture is more suitable for rear-wheel drive, and there is enough space for layout.

　　Compared with P0, P1 and P2 architectures, P3 architecture’s power transmission path does not pass through the gearbox, so the efficiency of pure electric drive and braking energy recovery is higher, and at the same time, the working time of the gearbox is reduced, which is helpful to prolong its service life. But the problem is also obvious, P3 motor can’t realize parking charging, and the shortcomings of outdoor camping and other use scenarios are exposed.

　　The representative model is BYD Qin PHEV, which is a parallel hybrid car with P3 motor as the core. With the original large-capacity battery setting, it not only meets China’s pure electric endurance of 50km for PHEV, but also can stack the performance of engine and motor to achieve stronger power output.

◆P4 architecture: realize four-wheel drive.

　　P4 frame motor and engine do not drive the same shaft, thus helping the vehicle to realize four-wheel drive. It can be a motor that drives the front axle/rear axle, or it can simply cancel the axle just like Acura NSX, and directly use two hub motors to drive the wheels. P4 architecture is similar to P3 in function, which can realize braking energy recovery and pure electric drive vehicles.

"2020 BMW i8 Extreme Night Meteor Limited Edition"

　　P4 architecture is mostly used in plug-in hybrid vehicles, and sports cars are more commonly used, such as porsche 918 Spyder, Acura NSX, BMW i8 and other sports cars. Take BMW i8 as an example. This 1.5T three-cylinder engine squeezes out the maximum power of 231Ps and the maximum torque of 320 N m. The maximum power of the permanent magnet synchronous motor on the front axle is 131Ps and the peak torque is 250 N m. It is equipped with a two-speed automatic gearbox to adjust the torque. The official acceleration time of 0-100km/h is 4.6s, which brings excellent power and can effectively reduce fuel consumption.

◆Ps architecture: parasites of double clutch

　　P3 motor is coupled at the output end of the gearbox, and Ps motor is directly integrated inside the gearbox. Because of the close location distribution, Ps architecture is easily confused as P3 architecture. Ps architecture is based on dual-clutch gearbox, which uses the characteristics of dual-clutch gearbox with two input shafts to integrate the motor on one of the shafts, and can realize pure electric drive vehicle and braking energy recovery.

"PS architecture power transmission mode"

　　The motor, clutch and reducer of Ps structure are put into the same shell, which is more fuel-efficient and smoother. But the disadvantages are also obvious, because the even shaft of the dual-clutch gearbox bears more torque than the odd shaft, which will lead to the inconsistency between the two shafts and the clutch wear; In addition, the integration of the motor into the gearbox will increase the maintenance cost, because it is the gearbox assembly that needs to be disassembled regardless of gearbox failure or motor failure.

"2021 Borui New Energy 1.5T ePro Leading Edition"

　　At present, among China brand car companies, Great Wall, Chery and Geely are all studying DHT gearbox, which is the cornerstone of Ps architecture. Taking Geely Automobile as an example, the 1.5T+7DCTH plug-in hybrid system of Geely ePro family models has the characteristics of high motor efficiency and high powertrain matching, and has the comprehensive advantages of high efficiency, excellent space and good quality (high cost performance). Among them, the efficiency of Ps frame motor is 97%, which is about 2% higher than that of P2 coaxial motor. The working speed of Ps frame motor is not limited by the engine, and the engine and motor can work in the high efficiency area at the same time, which can effectively reduce the fuel consumption of the whole vehicle.

●Combined frame motor

　　Brothers in battle, fathers and sons in battle, and motors with a single architecture all have shortcomings more or less, so combining two or more architectures of motors becomes the best solution at present. On P3 or P4 frame vehicles, it is necessary to install another motor for the engine in order to perform the engine start-stop and power generation functions, so many hybrid vehicles have two motors, forming a combined configuration of Px+Py. For example, WEY P8 has a BSG motor at the front end of the engine and a permanent magnet synchronous motor at the rear axle, which belongs to P0+P4 configuration. Let’s understand the technical characteristics of the combined structure motor through the development of domestic and foreign car companies and the analysis of car models.

◆ Volvo PHEV Technology Review and T8 Powertrain Analysis

　　In 2013, Volvo’s first-generation plug-in hybrid (PHEV) technology was applied to S60 PHEV models, adopting P0+P4 architecture, consisting of a BSG motor with 15kW engine front-end power and a 50kW permanent magnet synchronous motor with rear drive axle; In 2015, Volvo’s second-generation PHEV technology was applied to XC90 PHEV models, adopting P1+P4 architecture, consisting of an ISG motor with a power of 35kW and a permanent magnet synchronous motor with a rear drive axle of 60kW; At present, Volvo adopts the third generation PHEV technology based on CMA vehicle platform, and adopts a hybrid powertrain composed of an engine matching P2 motor.

　　As for the specific vehicle type, Volvo XC90 PHEV adopts a hybrid powertrain with P1+P4 architecture. The front axle of the vehicle is equipped with a gearbox integrated motor named C-ISG (Crank-integrated starter generator), which has three functions of start-stop control, power generation and assistance, and the rear axle is also equipped with a motor with the maximum power of 65kW. At present, Volvo’s PHEV models cover cars, station wagons and SUVs, all of which use modular PHEV powertrains.

◆ Evolution history of BYD DM system and analysis of the third generation DM system.

　　Since 2008, BYD’s DM system (Dual Mode system) has been upgraded twice. At present, the upgrade of the plug-in hybrid of the third generation DM is not only in terms of power, but also in terms of "performance" attributes of the whole BYD model after the "542" plan was put forward from the second generation DM system.

　　"High power consumption" is an obvious problem in the second-generation DM system. BYD thinks that BSG motor+electronic control system can solve the problem of "avoiding the inefficient area of the engine", assist the vehicle to generate electricity, make the whole energy flow system more balanced, and bring better acceleration performance, so the brand-new "BSG architecture" system is one of the core upgrades of this generation DM3.

　　The biggest purpose of BSG motor of the third generation DM system is not only to provide start-stop function servo for the engine, but also to charge the power battery while driving, and it can also be used to improve the acceleration performance. When the vehicle is driving in the all-electric drive mode, when the engine is involved, the BSG motor will drive the engine to start, so as to reduce the shock and assist in gear shifting.

Full text summary：

　　With the stricter emission standards and the support policies for new energy vehicles, OEMs pay more and more attention to the new energy market. Compared with the development of a brand-new hybrid system, the P2 technical route with modular design does not need to change the existing structure, is easy to integrate and is suitable for matching all gearboxes. Even if the fuel saving effect is not as good as that of parallel connection, the fuel consumption can be reduced at a lower cost, which has become a "shortcut" for many car companies.

"Listen, the leaves rustle, that’s the voice of the monkeys approaching. We will hurry up the mountain and try to observe the Yunnan golden monkey at close range. " Under the urging of Lai Jiandong, the stationmaster of Yunnan Baima Snow Mountain Wildlife Rescue Station, 13 students from Tsinghua University Institute of Economics and Management who participated in the summer social practice accelerated their pace.

Walking in a hurry, just to see the true face of the "gentleman" Yunnan golden monkey.

Yunnan golden monkey is a national first-class protected wild animal and an endangered species endemic to China. As the highest-altitude primate in the world, Yunnan golden monkey is only distributed in 7000 square kilometers of high-altitude virgin forest between Lancang River and Jinsha River at the junction of Tibet and Yunnan. It is regarded as the flagship symbol of biodiversity in northwest Yunnan and one of the most representative species in Yunnan.

"The reason why they are called’ gentlemen’ is that Yunnan golden monkeys are’ civilized and elegant’, and generally do not attack and harm humans, nor do they go to villages to destroy them. Yunnan golden monkey will not scratch or bite. However, it is still necessary to keep a distance to avoid injury and infection. " Lai Jiandong introduced while walking.

In 1960s, Yunnan golden monkey was once considered extinct, until 1964, when experts from Kunming Institute of Zoology, Chinese Academy of Sciences conducted an animal survey in Deqin County, Diqing Tibetan Autonomous Prefecture, they collected skins of Yunnan golden monkey, which confirmed that this species was not extinct. Yu Jianhua, a former hunter and 72-year-old monkey guard captain, recalled the Yunnan golden monkey and said, "When I was a child, I just heard from the old people in the village and never saw it with my own eyes."

In order to better protect Yunnan golden monkey, since 1983, Yunnan Province has successively established four protected areas, including Baima Snow Mountain, Yunlong Tianchi, Lanping Yunling and Lijiang Laojun Mountain, with a total area of over 478,000 hectares. In recent years, 990.66 hectares of Yunnan golden monkey habitat outside the protected area has been included in the protection scope, creating good conditions for the recovery and growth of Yunnan golden monkey population.

From 1997 to 1999, the special investigation of Yunnan golden monkey organized by Yunnan forestry authorities showed that the natural population of Yunnan golden monkey was 13 groups, with a population of 1400-1700. After years of protection, the population of Yunnan golden monkey has increased to more than 3300. "Baima Snow Mountain National Nature Reserve is the largest Yunnan golden monkey reserve in China, and it is also a paradise for Yunnan golden monkeys. At present, the number of Yunnan golden monkeys here has reached more than 2,500. " Lai Jiandong said.

Walking to an open field in the mountains, you can see dozens of Yunnan golden monkeys stopping on branches or chasing and playing in the mountains. The fur of Yunnan golden monkey is not golden yellow, but mainly gray-black and white. There is a pointed black crown hair on the top of the head, blue-gray or pink around the eyes and nose, and the nose is dark blue. The back, hands, feet and tail of the body are gray-black, and there are sparse gray hairs on the back. The abdomen, neck, buttocks and inner limbs of the body are all white.

"Usually, a Yunnan golden monkey population consists of an adult male, several adult females and several young monkeys. Adult male individuals are bigger than female individuals, and their buttocks are full of white hair, which is dubbed as’ white shorts’. After learning the survival skills, young monkeys will also leave the ethnic life. In the observation, we also found an all-male unit, which is composed of all male individuals. The members include the defeated and retired old male monkeys and the young male monkeys who have not formed a family. " Lai Jiandong introduced.

Over the years, Baima Snow Mountain National Nature Reserve has kept observing Yunnan golden monkey and steadily promoted the work of popular science education.

There is a popular science education base for Yunnan golden monkey in the nature reserve, covering an area of 334.16 square kilometers, which is the only place in the world where you can watch Yunnan golden monkey at close range. In the popular science education base, there are rare and protected plants such as Taxus yunnanensis and water green tree. In addition to Yunnan golden monkey, there are more than 10 rare and protected animals such as forest musk deer, red panda and black-necked pheasant. The forest coverage rate here is as high as 98.2%, which is called "a paradise for animals and plants". In the exhibition hall of the popular science education base, there are also many kinds of rare and protected animal specimens, among which the Yunnan golden monkey specimen with the largest number and the most complete scale is very precious.

As a window for close observation of Yunnan golden monkey, the popular science education base provides rich natural education resources. This summer social practice activity jointly organized by Zhongjin Public Welfare Foundation and Tsinghua University Institute of Economics and Management provides a useful attempt for students to explore how to effectively realize the harmonious coexistence between man and nature in a specific ecological and economic environment.

"The theme of this social practice is’ green and low carbon+biodiversity+rural revitalization’. In Lanping Bai Pumi Autonomous County, Zhongjin Public Welfare Foundation cooperated with China Green Carbon Sink Foundation to develop the’ carbon neutral forest’ project, and planted 112,000 fir and spruce trees. The project has not only achieved the goal of coping with climate change, but also an effective nature-based means to protect biodiversity. Usnea, a parasitic plant growing on fir and spruce, is one of the foods of Yunnan golden monkey. In order to allow students to visually observe the golden monkey, we chose to study in the popular science education base. " Lin Baichuan, team leader and member of the secretariat of CICC Public Welfare Foundation, introduced.

At the same time, CICC Public Welfare Foundation coordinated professional tutors in finance, economics, sociology and ecology, and designed four modules, namely, green finance, green transformation, community development and ecological protection, to help students conduct in-depth research on hot topics such as green and low-carbon development, conservation of germplasm resources and biodiversity, and unified carbon market construction, so as to enhance their knowledge and understanding of the country’s strategic layout, policy orientation and market behavior.

The eating of usnea by Yunnan golden monkey is also based on years of observation in the reserve. At present, there are 25 monkeys in Xiangguqing Yunnan Golden Monkey Protection Team in Baima Snow Mountain Nature Reserve, and its captain Yu Jianhua has been following Yunnan Golden Monkey for 28 years, rain or shine. "The monkey is very smart, knowing that there are pineapples here to eat, and some people are busy watching. Every morning, they come over to eat and play. We will follow them when they go up the mountain. We won’t go home until the monkey sleeps after 8 pm, and we will come to the monkey again at 5 am the next day. "

This group of relatives and observable monkeys is called Xiangguqing Yunnan golden monkey display group. More than 150 baby monkeys have been born, and the survival rate is over 85%. 125 Yunnan golden monkeys have been released in groups, which has well supplemented the number of wild monkeys and promoted gene exchange. At the same time, the number of people watching Yunnan golden monkey at close range has exceeded 300,000, which has greatly enhanced the popularity and influence of Yunnan golden monkey, and also provided a foundation for relevant experts and scholars to study the behavior and ecology of Yunnan golden monkey and promote the better protection of wild population.

Protecting wild animals and plants such as Yunnan golden monkey has brought good ecology and benefited residents in nearby communities. Bee farmer Yu Xinhua earns 20,000 to 30,000 yuan a year by beekeeping and planting Chinese herbal medicines, which is much higher than before. "I now have three bee farms with 60 boxes of bees, and the filtered honey can be sold to 140 yuan per kilogram. Good honey in a good environment is very popular, and some customers let me send it by express delivery. " Yu Xinhua introduced.

In the world natural heritage site with three parallel rivers, Yunnan golden monkey and 20% higher plants and animals in China live happily and roam the mountains. This vast alpine virgin forest ecosystem is a true portrayal of the harmonious coexistence between man and nature. (Huangshan yangshua)
