Answer: Those places where bicycles are repaired basically buy second-hand bicycles.

This is a common phenomenon in China. If you buy a new car, it will be stolen if you don't pay attention. If it is stolen many times, you don't want to buy it. Just buy it second-hand. The main source of used cars is stolen vehicles, which are generally sold to maintenance points, which is such a new "biological chain" of circulation.

Therefore, as long as you find more mechanics, you will get paid.
