How much do you know about Chinese food? There are many different kinds(种类) of food in China. Some of them are very popular(受欢迎).
There are also some different kinds of jiaozi. Others have sugar, eggs, and so on. I like jiaozi with beef very much.
Usually people make jiaozi at home. If you have no time to make it, you can eat it at the jiaozi house. Then you take it home and eat it with vinegar(醋).
When it comes, they always make jiaozi with their families together. Usually Chinese people put coins(硬币) in jiaozi. When someone eats the jiaozi with one coin in it, he or she must be very happy.
Which kind of Chinese food do you like best? Can you tell me about it?
