What about adults who want to learn the technology of quick car repair and quick maintenance?

It is very useful to learn quickly. There are more and more cars, and we all advocate three-point repair and seven-point maintenance in the process of using cars, so maintenance is just needed. Common items for quick repair and quick maintenance include engine oil, engine oil filter, fuel filter and air filter. After learning, you can open your own shop or have a market, even if you don't open a shop in the future, it's good to learn a skill.

If you are over 35-40 years old, you should be responsible at this age. Learning sheet metal and spraying is the best choice, and your salary is high.
