After saying this, Lin Feng said with emotion:

"Speaking of the accumulation of practical experience, it has always been a shortcoming of our Daxia. After all, we have a large population and a large number of students...

Ultimately, the practical teaching equipment resources allocated to each student are quite scarce.

This has resulted in the hands-on ability of our students in Daxia being far behind that of Western students.

But now everything has changed, because we have virtual worlds, and they are the second generation of virtual worlds!"

When Lin Feng finished speaking, the paused video continued to play.

"Wang Qing is a 42-year-old middle-aged man from the countryside. He is the pillar of a family!

However, he has been feeling a lot of pressure lately because both of his children have passed the college entrance examination and have been admitted to university.

The family still has the pressure of hundreds of thousands of loans to build the house, plus the daily expenses of the family...

On one hand, there is the mortgage, on the other hand, there is the university tuition and food expenses for the two children, and finally, the daily expenses of the family, which puts Wang Qing under considerable pressure. "

The narration in the video introduces Wang Qing's current situation, which is also recognized by countless people around the world.

Although they feel stressed out in different areas, they all bear tremendous financial pressure.

So at this time they were quite curious about how Wang Qing would solve the financial difficulties.

So along with their curiosity, the narration introduction of the video continued.

“I want to earn more money to repay the loan and support my two children.

The only way is to acquire more knowledge and improve your skills, so that you can gain an advantage in the job competition and get a higher salary. "

At this time, the video screen played the process of Wang Qing's hard work in learning knowledge through "Star Academy" in the form of memories.

The video then returned to the scene of a maintenance workshop, with narration accompanying it.

"Under this huge economic pressure, Wang Qing studied an average of 15 hours a day for a week.

He finally learned and mastered a lot of theoretical knowledge about automobiles, and understood the composition and structural types of various components of automobiles.

I also learned how to diagnose car failures, successfully passed the theoretical exam, and reached the level of an intermediate car mechanic in the theoretical class.

However, no matter how much theory you have mastered, you will never truly master it without practice.

Today is the time when Wang Qing completely transformed theoretical knowledge into his own knowledge and skills through practical maintenance exercises.”

Accompanied by the narration in the video, Wang Qing in the video then picked up a fault description file.

In this fault description file it says 'When the air conditioner is turned on, only hot air and natural air come out, no cold air.'

Seeing this, Wang Qing nodded slightly, as if he vaguely knew how to repair it, and showed a confident smile.

Then the repair process began in front of thousands of people on the scene and more than 9000 million netizens in the live broadcast room.

The maintenance process can be greatly accelerated, and many manual steps can be omitted.

For example, if you want to remove an air-conditioning compressor, it will normally take at least twenty minutes or even longer.

Now because it is a virtual world, you only need one command, and then you can remove the air-conditioning compressor instantly.

Of course, you can also dismantle it slowly according to the actual process to increase your real hands-on experience. As for how Wang Qing did it?

He did not dismantle the air-conditioning compressor immediately because the purpose of his learning automobile maintenance knowledge was to use it in real life.

If you don't do any diagnosis, but directly dismantle the air conditioner compressor and then replace it, then you are just a novice. So Wang Qing started to diagnose, first through the "one-key free installation detection instrument function" to check if there is any fault code, but there is no fault code.

Wang Qing then went to the engine compartment and checked the air-conditioning pipe pressure using the air-conditioning pressure gauge that had just been automatically installed with one click. He eventually discovered that the air-conditioning pressure showed abnormal data.

Because the air conditioning pressure gauge above shows that the pressure has become zero, instead of the normal pressure it should be.

So Wang Qing used the 'one-button free disassembly and assembly function' to allow the air-conditioning booster to increase the air pressure of the air-conditioning system.

Then I bent down and used various detection tools to check the leaking place of the air-conditioning pipe to see which part was leaking refrigerant.

After spending several minutes, Wang Qing did not find any obvious traces, and then used the "one-button free disassembly function" again to pressurize both ends of the expansion valve.

It was finally determined that there was no leakage in the air-conditioning duct in the engine compartment, but the problem was that there was a leak in the evaporator.

After determining the problem, Wang Qing directly used the "one-click disassembly-free function" and then obtained the air-conditioning evaporator box hidden in the cab.

The dark and wet marks on the air-conditioning evaporator box proved that there was indeed a problem with the air-conditioning evaporator box.

After confirming the result, Wang Qing naturally cheered and an excited smile appeared on his face.

The people at the scene were also very excited after watching this short few minutes maintenance video.

Because in just a few minutes, they discovered that Wang Qing had actually mastered the technology of car repair.

At least through this scene just now, it was proved that Wang Qing had learned how to repair the car air-conditioning system.

What’s even more exciting is that it would take at least an hour or even several hours to repair it.

Now, it is possible to have the 'one-click disassembly-free function' and the 'one-click installation of testing instruments function'.

The end result is a significant reduction in the time required for inspection and repair, which also means a significant reduction in the time required to gain practical experience.

This fully demonstrates the benefits of using virtual worlds to exercise and enhance practical experience.

It can be said that with the virtual world, students can acquire practical experience several times or even dozens of times faster.

After all, taking the automobile air conditioning failure repair as an example, if you originally wanted to gain this maintenance experience, it would take an hour or even several hours to get it.

But now, in just a few minutes, you can gain maintenance experience, which speeds up the process of gaining practical experience.

As for whether the practical experience gained in this way is useful?
After watching this video, people all thought it was useful, after all, you can't just learn one fault.

The following sped-up video also proves this point, in the troubleshooting of the car air conditioning system.

The causes of failure detected by Wang Qing were also varied, which made people stunned. No one expected that there were so many causes of air conditioning failure.

Some are problems with the mechanical system, some are problems with the sensor, some are problems with the wiring harness, some are problems with the plug, and some are problems with the ECU main board.

In this accelerated maintenance video, people feel the complexity of automobile maintenance and the rigor of practical teaching in the virtual world.

It can be said that if one has completed all the courses, then this person will definitely be a maintenance master in this field.

It is estimated that just by looking at a few data and then looking at the on-site fault, we can eventually accurately determine the fault location and speed up the repair time.

Of course, car repair is just one of the demonstration videos for practical learning.

Next, we come to a video of a junior high school student using the virtual world to learn chemistry practice and physics practice.

At this time, Lin Feng's voice also came out, causing people to pay close attention. (End of this chapter)
