How to treat the differences between North and South correctly?

In recent years, the use and communication of the Internet has become more and more popular. You can learn many different places and exotic customs without leaving home. Especially now that Tik Tok is on fire, there are many interesting jokes about the differences between North and South. There is a lot of stream of consciousness. Caused many friends to question whether it is a fake northerner? Fake southerners? Fake Sichuanese? Fake northeast people, etc ... Next, let's talk about a more objective analysis of north-south customs. In fact, what we generally refer to as the North-South difference is general. With the development of the times, the cultural differences between North and South are getting smaller and smaller. However, different natural factors have their own characteristics. For example, there are still climate differences. It is cold in winter in the south, not because of humidity, but because there is no heating. When heating is stopped in early spring and late autumn in the north, the somatosensory temperature is very similar to the cold feeling in winter in the south. There are still many differences except climate, topography, soil and resources. This also reflects the characteristics of China's vast territory and rich resources. Let's talk about human characteristics. The difference in diet is actually similar, and individuals in most parts of the country can adapt. The feeling of being sweet in the south and salty in the north is very general, and the taste is sweet, which is the characteristic of some areas, such as Shanghai. It does not represent the whole southern region. It doesn't seem right that the south is light and the north is heavy, but each has its own taste and varies from person to person. Many friends around me in Sichuan and Hunan don't know how to eat spicy food. However, local specialties can not be ignored, which also reflects the wisdom and love of our ancestors. Personality differences, Renye Fang is not "bold" (subconsciously rude and savage) and Renye Fang is not "gentle" (subconsciously introverted and stingy). Personality differences have nothing to do with north and south. Like a film and television drama, literary books are written, directed and written by the south. Don't northerners understand?
