Companies generally don't check. If the company wants to check, it must go to the public security bureau, which is very troublesome. If it is a special position, the company will check you, and when you join the company, you will be asked to open a certificate of innocence, so there is nothing you can do, because the meeting given to you by the Public Security Bureau will show your criminal record. You don't have to work for others. You can't earn much money in your present job. It's best to start your own business, especially to be close to your family and relatives, so that you won't take the old road. People can't control themselves when they are upset. More care and encouragement is the most important thing.
