1. On the first day of subduction, there was a "jiaozi Erfu surface" in the north. The custom of "laying eggs on pancakes" is that in the south, such as Shanghai, wonton is eaten, and in Guangzhou, noodle soup is eaten. Noodles are rich in carbohydrates, which can provide enough energy and absorb a lot of water during cooking, so they will have a strong satiety when eaten.

2, Hangzhou people "head ham and two chickens". Chinese medicine believes that ham has the effects of strengthening the spleen and appetizing, promoting fluid production and benefiting blood. Ham can be eaten all year round, but it is best to eat it in summer. In summer, people often lose appetite and lack nutrition. Ham is rich in nutrition, not greasy when eaten, and can stimulate appetite. When cooked with wax gourd, ham is nutritious and can prevent heatstroke and dispel diseases.

3. In some southern areas, such as Shanghai, people want to eat wonton. In fact, for southerners, wonton and jiaozi are almost a kind of food. Shanghainese have the saying "Toufu Wonton Erfu Tea". Compared with dumplings, wonton is thin and transparent after cooking. In addition, it takes a short time to cook wonton, and cold water needs to be added several times to ensure it is cooked thoroughly. Another point is that dumplings are heavily dipped and wonton is heavily souped, especially in Guangdong. Chicken soup and meat and bone soup are the first choice for soup base.
