Twin giant pandas "Mengbao" and "Mengyu" are playing in the museum. Reporter Deng Wei photo

　　Beijing Daily News (Reporter Ye Xiaoyan) Since yesterday, two new members have been added to the Giant Panda Pavilion in Beijing Zoo. The twin sisters "Meng Bao" and "Meng Yu" born in Chengdu, Sichuan officially moved into the Giant Panda Olympic Pavilion. At this point, the Giant Panda Pavilion in Beijing Zoo has made up the "Top Ten Generals".

　　Yesterday morning, two twin giant pandas, one year old and five months old, made their official appearance in the middle exhibition hall of the Olympic Hall of the Giant Panda Pavilion in Beijing Zoo. As they were still adapting to the surrounding environment shortly after staying in the independent room, they tried to climb in the indoor playground for a while, and then picked up bamboo to taste it.

　　The two giant pandas, named Mengbao and Mengyu, were born in Sichuan on May 23, 2018. They are twin "sister flowers". "Like humans, the breeding of giant pandas should also pay attention to the adjustment of blood relationship." The relevant person in charge of Beijing Zoo told the reporter that in order to adjust the consanguinity of giant pandas and maintain the genetic diversity of the population, Beijing Zoo and Sichuan chengdu research base of giant panda have been carrying out cooperative breeding projects for giant pandas for many years.

　　The father of Mengbao and Mengyu is Meilan, and the mother is MengMeng. This pair of giant panda couples is well-known, so when the twins were born, they attracted much attention from all walks of life. The two giant pandas weighed only 149.2g and 110.7g at birth. After a year and five months of growth, they have now grown to 40.5 kg and 39 kg.

　　After their birth, the twins lived with their mother "MengMeng" in Chengdu, Sichuan. "Generally, panda cubs will learn to eat bamboo when they are five months old. In six months, they will grow 20 teeth, including canine teeth, incisors and premolars, and begin to formally chew bamboo leaves. Giant pandas in captivity will wean at the age of six months to one and a half years old." The staff introduced.

　　With the gradual growth of twin sisters, under the premise that all conditions are suitable, Beijing Zoo negotiated with chengdu research base of giant panda, Sichuan, and took two giant pandas to Beijing on September 10th. "Just like weaning a child, we should choose the right time. The reason why I chose to come to Beijing in September was because the weather in Beijing at that time was more suitable and the bamboo varieties that I could provide were also rich. " The staff said.

　　Changqing Li is an experienced giant panda keeper in Beijing Zoo. At the beginning of September this year, he was sent to the base to live with the twins for half a month, in order to make the twins adapt to the keepers and feeding methods in advance. On September 10th, the twin giant pandas flew from Sichuan to Beijing Zoo, and stayed in the quarantine yard for one month.

　　During the quarantine period, Changqing Li remained their keeper, feeding and training at the quarantine yard every day, and observing the twins’ every move. At the same time, veterinarians also pay close attention to the physical conditions of Mengbao and Mengyu, and conduct regular deworming and observation to ensure the health of the two giant panda cubs during the quarantine period. Now, after a month of strict quarantine, the twins have adapted to the environment in Beijing. "Generally, giant pandas live independently, but the two sisters have lived together since childhood, so they live together temporarily and then raise them separately when they are older." Changqing Li said.

　　Up to now, the total number of giant pandas living in Beijing Zoo has reached 10. They are Dadi, Jini, Gugu, Mengda, Menger, Menglan, Diandian, Fuxing, Mengbao and Mengyu, and the parents of three giant pandas are also Mengda, Menger and Menglan. Five giant pandas, Fuxing, Menglan, Diandian, Mengbao and Mengyu, meet the tourists in turn.

　　In order to make the pandas live more comfortably, the breeders have also taken great pains. They not only added green plants to the indoor sports ground, but also added "amusement facilities" such as rocking chairs and perches to the outdoor sports ground, and also adjusted the position of placing bamboo to enhance the panda’s feeding pleasure. Feed mix is also particular. The breeder will adjust the food mix according to the individual needs of each giant panda, and raise it scientifically and accompany it attentively.

It has been driving for 6 or 7 years in a blink of an eye. This car really makes me love and hate. Needless to say, I believe the owner can understand. What I hate is that there are frequent minor problems after the mileage, and most of them are problems caused by material technology. The problems are not big, but it is a bit disgusting to waste money and time.

A few years ago, I saw what everyone said about return pipe fracture, and I didn’t take it seriously at all. Unexpectedly, at 60,000 kilometers, I was really thrown on the road because of the broken pipe. From then on, I began to pay more attention to all kinds of problems warned by everyone in the forum, and also started to buy oil and materials to maintain myself, and solved all kinds of small problems by myself. I never went out to do it myself. I even bought a small Alto to disassemble and install it. From I didn’t know the sleeve before to a lot of auto repair tools now, I have gradually developed driving into my only hobby besides fishing. Most of the time, I enjoy the process of solving problems and save money by the way. Sometimes when I look at my son’s house full of toy cars, I really feel that cars are men’s toys for life.

In fact, the lid was changed in November last year. I wanted to open it for a while to see if there were any problems. As a result, it was delayed again and again. Now it has been opened for 6 thousand kilometers, and everything is normal. I must hand in my homework, which is also a souvenir for myself!
Pick something important before you start:
1. The oil circuit involved in this operation is dangerous, so the power must be cut off first, and the battery is located on the right side in the trunk! ! !
2, the owner of a BMW must have: ISTA software, with 20 g installation files and more than 100 g installed. It is recommended that a fish be bought directly, which is very cheap and convenient.
3. Torque wrench. There was a 10-150nm wrench before. Because some screws have single-digit torque in this operation, I bought a 5-60nm wrench for accuracy.
4. BMW star-shaped sleeve. At that time, I didn’t buy a sleeve because I had a simple star-shaped 7-shaped wrench. As a result, a screw was not screwed in place, which was almost tragic (detailed later)
5, ratchet wrench, hexagonal sleeve, I have all kinds of ratchets, not big brands, very cheap. Electric wrenches, hand drills, etc. If there are elastic screws, it will save a lot of effort.

I have been studying online for a long time before I started, and I have a good idea of all links, and the tools and materials are also available. I can’t wait to itch. Finally, I specially arranged for two days, which started on a sunny morning! Because of the whole operation by one person, I can’t see the photos completely now. Please forgive me!

The scene of the crime was in a shed where sundry goods were kept in my hometown. I usually live in the city and come back to repair my car, mainly because I am afraid of being disturbed: if someone is watching or even talking, it will affect my state and I can’t concentrate. Second, I’m afraid that there may be no sandstorm or rain outside one day. After all, turn on the engine and don’t get into the sandstorm and dust. However, there is a big hidden danger that if you can’t start the car after you finish it, it is not good to tow it. (Yes, I’m ready to roll over.)

Without a notebook, it is also very convenient to put a PC with a small host on the tool cart. As a non-professional, it is necessary to operate strictly and scientifically to avoid overturning as much as possible! Open ISTA to escort the next operation.

Remove all the engine decorative covers, and then remove the adhesive tape and the left and right covers at the position shown in the figure.

Then remove the tie rod as shown in the picture, and forget to shoot it. Note that the position of 1 should be pried open, there are screws under it. Remember to loosen these big screws. I used a new electric wrench. Wow, it’s so easy. The tightening torque is 56NM, and a torque wrench can be used for installation.

It is reasonable to say that everything blocking the valve cover should be removed. ISTA said that this soundproof sponge should be removed. I didn’t remove it, but it didn’t affect much, but it seemed to be torn a little.

The cover is located here, and all kinds of plugs and pipes that get in the way should be removed.

All kinds of plugs, once pulled out, many have to be tilted with the help of a flat screwdriver, with a little ingenuity. Pay attention to the age of the car, the plastic is not so strong, don’t be too violent and be careful to damage it.

This board is in the way, you’d better remove it. Be careful when loosening the screws in the circle, and it will fall easily.

Dismantle the ignition coil and spark plug. Everything that gets in the way has been removed. The four-cylinder spark plug has never been removed so smoothly.

There was obvious oil leakage around the oil filler, and then a washer was replaced, and the problem remained!

Loosen the high-pressure oil interface connecting the oil rail, and find an old piece of clothes to wrap around to prevent gasoline from leaking out.

The red circle is the oil rail, and the green one is the high-pressure oil circuit.

Now it’s one of the biggest difficulties in this operation. The formal process is to first remove this row of small screws, remove the fuel rail, then remove the fuel nozzle with special tools, and then connect the fuel nozzle and the fuel rail according to strict requirements when installing. The whole process is very complicated, which will make you flinch. And my method is as shown in the figure: directly remove the whole fuel rail and fuel nozzle with a crowbar, and skip this most complicated part of the operation! (The method comes from the foreign great god of tubing, thanks to the inspiration of the great god)
The fuel rail is very strong. If you don’t trust it, put something on the contact surface between the pry bar and the fuel rail, slowly apply force, and tilt the left side and the right side.

I peed after a general look.

Carefully tilted for a long time, and then slowly pulled out after loosening, which felt wonderful.

It was so dirty, I searched temporarily for how to clean it, but I gave up without tools. Later, I wiped the outside with clean paper very carefully.

Both the high-pressure oil pump and the pipe are removed. By contrast, this operation is too simple. Remember to pad something, or gasoline will spill.

Then came another difficulty. To remove the VANOS solenoid valves of the two camshafts, which are located in the red line area facing the cockpit, it is extremely difficult to pull out the plug. After a long time of observation with various flat screwdriver and endoscope, it was unsuccessful, and the clip of the plug was also broken, let alone unscrewed the two solenoid valves.

This is the plug shape photographed by endoscope, which is actually similar to the plug of spark plug ignition coil. I don’t know how professionals unplug the plug, or just unscrew the solenoid valve. Without special tools, I screwed and used various tools for a long time, but I didn’t succeed. Later, when I was too tired at night, I went to bed and prepared to get up the next day!
I feel like it’s getting dark when I’m doing nothing. In fact, I’ve been doing this job for almost a day. When I’m tired or hit a bottleneck, I’ll smoke a cigarette or brush my mobile phone, or even lie in bed for a while. Professionals estimate that it will be done in an hour or two. Again, we don’t work to make money, but we enjoyed the process.

In the evening, I searched a lot of maintenance videos, all of which were to remove the solenoid valve first, which led me to get up early the next morning or continue my previous thinking. After all kinds of attempts, I still couldn’t remove either the solenoid valve or the plug, so I wanted to put it back as it was from time to time! But it is really unwilling to go here!
(In order to avoid falling into sundries, I stuffed all the holes exposed on the cover with dust-free paper, not toilet paper.)

I don’t know if it was God’s blessing. Just when I was in a desperate situation and almost gave up, I suddenly thought of another plan: since the connected pipes are all soft, it is not bad to remove the cover first!

When you have the idea, the rest is easy to say. Loosen each screw according to the prompt.

Although the screws have been loosened, the combination is still quite tight. Carefully separate the four sides, carefully avoid all obstacles, slowly find the angle to lift the lid out a little, and finally open it! (It’s easy to say, but it actually took a long time.)

The white clip of a plug has been broken by me.

This annoying plug, once you ignored me, now you and I don’t care, so we can easily unplug it.

Just like the goddess took off the only gauze, my heart came and went at that time. . . . Look at it carefully for a long time

Camshaft, timing chain, valve stem. . . The understanding of the engine is further deepened.
The sealing washer should be carefully removed, and the contact surface should be carefully cleaned with dust-free paper.
I also thought of the kind of words that everyone loves to ridicule, "The use of water and oil causes the engine to open the cylinder." . .
Haha, there are too many common cognitive misunderstandings caused by various factors, which require you to have the ability to question and think independently!
When you understand many things, you often fall into pain. . . Uh … . Digress

The next step is simple, take out the new cover that has been prepared for a long time.

Screw on the solenoid valve. It should be noted here that I have tried several times. After screwing on the solenoid valve, one of the clasps in the figure will be displaced every time, so it is necessary to manually break the clasps back to the correct position. That is to say, if you don’t remove the cover, directly replace the solenoid valve, even if there is a special disassembly and installation tool, there is a great chance that it will not be installed in place, and you still can’t see it. I don’t know what hidden dangers there will be!
Besides, I didn’t notice that my solenoid valve was "goo" until I finished it. . Goo. 。” The croaking of frogs is very common on the Internet. It can be solved by replacing the solenoid valve, but it’s too lazy to disassemble it after it’s installed. I don’t feel any other abnormalities at ordinary times. Let’s leave it on first.

This is the old cover that has been removed. Basically, there are cracks in the position shown in the figure, which causes oil to penetrate into the first and second cylinders, causing oil consumption and oil immersion in the spark plugs of the first and second cylinders!

This is an oily two-cylinder spark plug before replacing it. I checked it once after driving for two or three thousand kilometers. It was extremely dry. I couldn’t find the photo. I will make it up another day!

When installing a new cover, the rain deflector in the red circle is a little in the way and wants to be removed. Who knows that the position of the green circle is too tight to be removed and it won’t rain, so give up. Later, it was found that the wiper needs a lama, which has been purchased and can be removed next time!

Tighten all the screws in strict accordance with the requirements in sequence. I screwed them twice as required. The first time, I screwed them half a turn, and the second time, the torque was 8nm. That’s the good thing about doing it yourself. You can twist it as you want! Outside the repair shop or even the 4S shop, there is a high probability that it will not be so careful.

Take advantage of the gap to wash the spark plug again, and the insulating silicone grease that has been bought for a long time also comes in handy.

Return all the parts and plugs in the same way, so I won’t go into details, but I don’t know where this screw is installed.

After searching for a long time, I found that the oil inlet pipe was fixed here. It was almost tragic that this screw was not screwed properly.

There is a little trick: install the screws in the disassembly order with the lattice storage box, so it is not easy to add more screws. . .

Everything has been restored, and I have repeatedly checked it several times. The most tense moment is finally coming. Can I light the fire successfully? Do you want to call a trailer?
Bite your teeth and close your eyes. Fight!
Chug chug. . . I have never felt the roar of Bavarian tractors so beautiful! Once successful, my inner sense of accomplishment will overflow, and at that moment my mouth can’t help but rise 45 degrees!
At that time, I even had an impulse to clean this shed, decorate it simply, dig a trench, install air conditioning and lighting, and display my car tools. . . . Wow, what a beautiful picture that is.

Holding back my inner ecstasy, I couldn’t wait to drive out! I should have come back after trying for two or three kilometers, but I was too proud to drive for more than ten kilometers to come back. This is a tragedy.

I’ll go. What’s the matter with the oil stain on the ground? I’m stunned in an instant. Open the cover and check it.

Yes, that’s the last oil inlet pipe screw.

I used a torque wrench to tighten all the screws in ISTA, because there was no star-shaped sleeve, and the last oil inlet pipe screw was screwed with this simple wrench, because the screw was connected with a long head, and the short head was not able to exert force, which led to inaccurate torque estimation, thinking that the tightening was actually not up to standard! Sure enough, there is oil leakage in this position. . . .

Fortunately, there was not much oil leakage when I found it, and I felt a hundred milliliters. It’s a little scary. . . Turning around, I quickly started a whole set of star sleeves, and the money for tools can’t be saved!

After typing so many words, my neck is sore. I turned my head and looked out of the window. It was already dark! I’ve been writing for almost a day, and I wasn’t so serious at school.
Really interest is the best teacher, relying on the knowledge learned online, I completed a self-improvement in auto repair, thanks to BMW’s unreliability for giving me this opportunity hahaha!
Also declare that this post is intended to share experience, not as a specific operational guide. If you need to be extra cautious in operation, it is best to have professionals around you!
Pure manual code word, I hope you like it, don’t spray it if you don’t like it, thank you!
Finally, I wish everyone can have a deep and long-term love with their car.

My cousin used to set up a street stall and drive a set. Because of the layout of three rows of seats, a family of four is not only spacious, but also can hold a lot of goods. Last year, my cousin completely ended his street stall career, found a stable job, and earned a considerable income. For the new van, it became a regular means of transportation for walking and family travel. At the end of August this year, he sold his own and replaced it with an Changan Plus, but less than a month after it was opened, he expressed regret. What happened?

Two days ago, I visited my cousin’s house, and saw the Changan Plus he just bought, with a red design. It was not only sharp and dynamic, but also very festive. For ordinary working-class families, it was already very satisfying to drive such a coupe, but when it came to this car, my cousin was not happy, and even said that he had some regrets.

It turned out that my cousin bought a 1.4T version of the 2022 model with a price of 93,900 yuan. In fact, he had been paying attention to this model for a long time before. Because he had some spare money in his hand, he took his cousin to see the car during the break. After understanding it, not only did the car itself have certain discounts, but the country also had a policy of halving the purchase tax, so he bought it as soon as his mind was hot.

First of all, for the appearance of this model, my cousin and my wife fell in love at first sight, and they liked it very much, which looked more beautiful than the picture. After all, the 2022 Changan Plus has gone through several generations, and now it is the third generation version. Its appearance is both calm and dynamic, and so far, it has 1.2 million users, so it is well-known in terms of quality and practicality. As far as it is concerned, its average monthly sales volume is 10,000+,and finally my cousin and sister-in-law failed to resist the temptation.

The interior design of Changan Plus is just what my cousin and sister-in-law want. Although it uses a conjoined large screen, it looks very harmonious. The D-shaped rudder+yacht-type electronic gear lever is full of fighting atmosphere. Although the whole interior is simple in style, it highlights a touch of luxury, which is very desirable in both layout and color matching.

In terms of space, as a 5-seat car, it can easily meet the collective travel of my cousin’s family of four. After all, it has a length of 4730mm, a width of more than 1.8m, and a wheelbase of 2,700 mm. The space performance in the back row is at the same level as that in peace, and even it has a unique advantage. Not only is the space wider, but the protrusion of the central platform is not so obvious. In the case of five people, it has a higher height.

However, when it comes to its power, it is equipped with a 1.4T engine of Blue Whale, which can produce 160 horsepower and a peak torque of 260N·m, matching the wet dual-clutch gearbox of 7DCT. Although the throttle response will be slightly delayed when the torque is low, the power response will be very positive when the speed climbs, which is much stronger than the previous Wuling. When you want to overtake in the city, you can do it with one foot throttle. Moreover, its comprehensive fuel consumption is only 5.6L, which is acceptable in terms of travel cost.

In terms of configuration, a 90,000-class coupe has been given a series of practical functions such as 360-degree panoramic image, 180-degree perspective chassis, cruise control, driving mode selection, uphill assistance, sunroof, keyless start, 4G network connection, online map and remote start, which can easily meet daily use.

When it comes to this, I seem to feel a little wrong. It can be seen from the whole process that my cousin is very satisfied with the performance of Changan Plus in all aspects. Then why do you say that you have some regrets about buying this car? And my cousin’s next words made me see the essence of the problem clearly.

Because my cousin’s family likes picnics and outings, for the previous one, it is a front-mounted and rear-driven setting, which not only has a high chassis and good passability, but also can go up and down the mountain, play everywhere, and go to places that many ordinary models can’t go. At the same time, as a van, it doesn’t feel bad when bumping into it, and it can be unscrupulous in the wild. Although this car has no class at all, its high practicality has brought endless joy to my cousin’s family of four.

However, when you change this Changan Plus, you can’t do whatever you want when you go to the wild. First of all, it is a front-drive structure, and the chassis is low. Don’t say that you should be careful when you go up the mountain and into the water, or even take some bad roads. As a result, you will behave prudently in the wild and you can’t do whatever you want as before. After all, you are afraid of bumping into a new car. Therefore, its field activities are limited to some extent. Therefore, in this respect, my cousin always misses the days he had before, and it is no wonder that he regretted it less than a month after he bought it.

Of course, for Changan Yidong Plus, on the whole, there is nothing wrong with the vehicle itself, and all aspects of performance can satisfy my cousin and sister-in-law, but different models have different uses and functions, so I can only say, "What suits me is the best", what do you think?

Today, let’s talk about a car that is quite popular recently. What attracts me most about Fengyun T9 is its price. From 129,900, there are more than 10,000 discounts, and now it is only 119,900. This cost performance is really nothing to say. Coupled with rich configuration, large space, good power and fuel consumption, I think this car is worth considering.

However, if we want to talk about shortcomings, I think its modeling design is a bit lacking in originality. Although there is a new "listening to the wind" grille, it looks quite like an electric car, but the whole is still too similar. However, the 20-inch wheels and penetrating taillights are quite handsome, giving people the feeling of a high-end car.

Speaking of space, this car really has no choice. It is 4795mm long, 1930mm wide, 1738mm high and 2770mm wheelbase. Although it is smaller than Tiggo 9, it is still very spacious. Best of all, its "occupancy rate" is as high as 70.04%! What is this concept? That is to say, the space utilization rate in the car is particularly high, and it is particularly comfortable to sit. Besides, you can choose the 5-seat or 7-seat version. The second and third rows of seats can also be put down with one button, and 12 different space combinations can be created. I think this design is particularly practical, and it can be easily handled whether it is a daily commute or a weekend trip.

When it comes to comfort, Fengyun T9 is really bloody. Dual floating large screen, HUD head-up display and wireless charging are all standard. But what surprised me most was its seat. The main driver’s seat has 10-way electric adjustment, 10 airbag massages, and 3 gears of ventilation and heating. Sitting on it feels as comfortable as lying on the sofa at home.

The copilot is even more exaggerated, and it is directly called "Queen’s copilot". In addition to the function of the main driver, it also adds electric leg rest and one-button reclining. Sitting on it is simply enjoyment! I think these configurations can already be compared with some luxury brands. If you like comfortable driving experience, Fengyun T9 will never let you down.

In terms of safety, Fengyun T9 has also made a lot of efforts. It uses a cage body, and high-strength steel accounts for 85%. The door frame is integrated, and the lateral coverage of the front anti-collision beam has reached 85%. These designs are designed to better protect passengers in the event of a collision.

For hybrid vehicles, battery safety is particularly important. Fengyun T9 uses the "Guardian" battery safety system, and the battery case is made of aviation grade aluminum, which has strong anti-collision ability. And it has IP68 waterproof rating. Sorry I didn’t finish just now. Let me continue to introduce the safety performance and other features of Fengyun T9 to you:

In addition to what I just mentioned, Fengyun T9 also has a very powerful function: it can cut off power protection 2 milliseconds after the accident. This speed is really fast, which can greatly reduce the secondary injury after the accident. In addition, Fengyun T9 comes standard with 7 airbags, and the length of side air curtain reaches 2060mm. Such a long air curtain can basically protect the whole carriage. I think, with so many safety configurations, you can really feel at ease when driving out.

Speaking of power, Fengyun T9 uses Kunpeng super hybrid C-DM system. This name sounds quite tall, but it’s actually really good. It uses the fifth generation ACTECO1.5TGDI engine, and its thermal efficiency is as high as 44.5%. With the electric hybrid system with efficiency as high as 98.5%, the power output of the whole vehicle is really strong. The specific data is as follows: the maximum total power is 280kW, the maximum total torque is 610N·m, and the acceleration from 0 to 100 km/h takes only about 7 seconds. This acceleration is comparable to that of some sports cars.

But what surprised me more was its fuel consumption performance. Under WLTC working condition, the fuel consumption per 100 kilometers is only 5.2L, and a box of oil can run 1152 kilometers. You know, this is a medium-sized SUV! I think this fuel consumption level is already excellent.

Speaking of battery life, Fengyun T9 is also very powerful. Under CLTC condition, the pure battery life can reach 120km. If the combination of oil and electricity is included, the total cruising range under WLTC can exceed 1400km. This endurance, even if you travel long distances, is completely fine. The charging speed is also very fast, and the power can be charged from 30% to 80% in 20 minutes. This means that after you have a cup of coffee, the car can be charged and continue on the road.
