There are jokes about jiaozi.

A long time ago, Old Master Q once traveled around the world with two lovers. One day, when they were walking hungry, they found a small shop in front. When they came closer, there was a sign at the door, which read: "Authentic sweet-scented osmanthus dumplings are worth a penny." Old Master Q felt in his pocket and found that there was only one penny left. In desperation, the apprentice took out his pen and added a vertical to the word "one", which became "ten pence" Then the master and apprentice walked into the shop and asked for ten glutinous rice balls. Confucius and other three people finished eating, took out a penny to the boss, turned around and went out of the store, and the boss quickly chased out of the store to ask for money. Old Master Q pointed to the signboard and said, "Clearly mark the price, and you get what you pay for!" . The boss was speechless for a moment. When Old Master Q left, he patted the boss on the shoulder and said with a smile, "I'd better be polite to you today, otherwise, I'll add some more and turn it into" authentic sweet-scented osmanthus dumplings, 1000 pence! "" .
