As a service consultant or mechanic in a 4S shop, will you be fired after 40? Or what will it make you do again? After 50?

How can I put it? No matter what position you hold, there is no iron rice bowl now. After 60 years old, you naturally have old-age insurance and your children. You can do well in the automobile industry if you like. When you are old, you can be a manager. After the age of 50, as long as you manage it well, you can be the general manager and consultant of some automobile companies, without worrying that each industry has its own characteristics.
