The climate in the south of China is hot and rainy, and the cultivated land is mostly paddy fields, so local farmers plant rice with high temperature and rainy growth habits according to local conditions.
There is less precipitation and lower temperature in the north of China, and the cultivated land is mostly dry land, which is suitable for the growth of dry and cold-resistant wheat. The so-called "eat what you plant", in the long run, has developed the traditional eating habits of the south and the north.
2. Difference of ingredients
Northerners like to eat scallions and garlic, especially scallions, which are dipped in sauce and rolled into pancakes. Northerners can't make soup or cook without the company of scallions.
Southerners mostly use onions and garlic commonly used in the north as ingredients, and rarely eat them directly.
3. Difference of staple food
Northerners eat noodles, steamed bread and cakes, while southerners mainly eat rice. Northerners feel that rice is not enough one by one.
Southerners think that noodles, steamed bread and cakes are just snacks, and rice is the staple food.
