China is very famous(著名的) for its food in the world. There are many kinds of food in China. They're Cantonese(广东的) food, Sichuan food, Shanghai food, Hunan food and so on. And I like Sichuan food best.
Now, Sichuan food is very popular. There are many Sichuan food restaurants all over the country. Sichuan food is very hot(辣的), but people love it. In some famous Sichuan food restaurants, you can see many people waiting there. Now in Beijing, there are more and more Sichuan food restaurants.
