The easiest way is to play games, such as a game of chess for ten yuan, and you will get the money if you win. Or set up a chess stand and study the arrangement of the rivers and lakes. (But beware of the police) If you want to be a coach and take an apprentice, it depends on your chess skills. Participate in the competition. This road is more difficult than the previous one. The simplest thing is to set up a stall to cheat money and then wait for an opportunity to run away. This requirement is not high, so I think it may suit you. As long as you are a little smarter. )
