Jiao (commercial guild)

Okay, let me tell you about jiao which is a kind of group that people join when they do business. You know how you have friends who you like to hang out with and play games with? Well, grown-ups have friends they like doing business with too and they call these friends their jiao. It's kind of like a club for people who sell things.

When people join a jiao, they can get help from other members who know how to sell things really well. They can also get loans from the jiao if they need money to start a new business or buy more things to sell. And if someone is doing something wrong in their business, the jiao can help make sure they fix it so everyone is selling things fairly.

So, imagine you have a lemonade stand and you join a group of other kids who have lemonade stands. You can help each other figure out how to make your lemonade taste better or how to sell more cups. You can also borrow cups or lemons from each other if you run out. But if one kid starts cheating by using old lemons or not giving the right change, the group can talk to them and make sure everyone is playing fair. That's basically what a jiao does for grown-ups who sell things.
