Southerners are more careful about their diet. Southerners like to simmer slowly, so the overall characteristics and forms are more detailed. Northerners like to drink in large bowls and eat meat in large chunks, so the overall style and connotation are relatively rough. Besides, there are some differences in soup. There are some substantial differences between soup in the south and stew in the north. Soup in the south is used for cooking. Stew slowly and cook for a long time. Especially in hot weather, but northerners do drink soup all year round.
And it is a necessity after meals, especially in winter. I like to drink hot soup. Southerners like rice, but northerners like pasta. Because northerners think that the starch content in noodles is relatively high, which can satisfy hunger and tastes good. I think rice will be very complicated to eat, and it will be accompanied by many dishes, which is very anti-hungry. But southerners think that noodles are just used to make some beautiful and exquisite snacks. Snacks are used to entertain guests, or snacks after meals.
Can't be a staple food. The stuffed buns in the north are big, but relatively simple. There are many kinds of steamed buns in the south, such as barbecued pork buns, fried pork buns, yellow cream buns and so on. Moreover, the difference in diet is sweet in the south and salty in the north, and the temperature in the north is relatively low and very cold. But summer is very hot, so northerners will pickle some vegetables before summer comes. So you can eat it in winter, which is especially delicious.
