In China, there're many different kinds of food. Some of them are very popular. The real Chinese food is dumplings. Now let's talk about them, OK?
Everyone in China likes dumplings very much, and there are many different kinds of dumplings. Some have meat and vegetables in them, others have sugar, eggs and so on. I like dumplings with vegetables and pork better than any other kind.
Usually people make dumplings at home. If you have no time to make them, you can buy them from any supermarket. Then you take them home and eat them with vinegar.
The Spring Festival is very important in China. When it comes, we make dumplings, usually we put a coin(硬币) in a dumpling. If one eats the dumpling with the coin in it, he or she will be lucky in the year.
In the old days, people couldn't often eat dumplings, because they were very poor. Now our country is becoming stronger and stronger, and our people are richer and richer. We can eat them very often.
Now tell me, do you like dumplings?
Welcome to China, and we'll invite you to eat the real Chinese food —dumplings.
