Geographical environment has created different tastes of agricultural products in different places. In areas lacking salt, such as Yunguichuan, spicy food is used instead of salt. Guangdong, Guangxi and Hainan enjoy soup because of their hot climate and light taste. Because the food crops in the north and the south are different, the north likes pasta, the rice in the south is the staple food, and the coastal areas should be close to the ocean, so seafood has become the first choice for dining tables.
