In ancient times, the Yellow River was the birthplace of Chinese civilization, and people relied on the river to survive. The Yellow River is in the north and is suitable for people to live in. The south is humid and hot, not suitable for people to live, and there are very few people there. Usually, the "barbarian land" refers to the south. That’s why northerners call southerners Nanmanzi. In ancient times, barbarism meant being rude and lacking in self-restraint. Most of the people in the south live in the mountains and forests, "along with animals all day long" and are not bound by etiquette. Therefore, the people in the Middle Kingdom despise this and call them southern barbarians.

The differences between southerners and northerners:

1. In terms of height, northerners are generally taller, while southerners are generally shorter.

2. In terms of language, northerners speak close to Mandarin and have standard pronunciation; southerners have a heavier accent and non-standard pronunciation.

3. The way to deal with problems is that northerners are straightforward and impatient, while southerners are delicate and alert.

4. How to make friends. Northerners like to make friends with wine, while southerners generally make friends through activities.

5. Dressing style, northerners like trousers while southerners like skirts.

Warm reminder: Both southerners and northerners are descendants of Yan and Huang, and the differences are caused by the environment and cultural customs.

Characteristics of northerners: They like to build relationships, worship power, and are obsessed with politics. However, when facing interests, they often take the overall situation into consideration and have principles and positions.

Characteristics of southerners: Not good at fighting and fighting directly. They like to live a stable life and manage their own lives. Therefore, they value their own interests more. As for what society is like and who governs it, they don't care so much.
