Why do Northeastern people have such strong language skills?

This is related to personality. There are relatively few reserved people in the Northeast. Generally outgoing. For example: in Changchun. You can chat with the street cleaners and sanitation workers casually while walking on the road. It is very common to hand a stranger a cigarette. And the cleaning staff will also take the initiative to chat with you about today’s weather! The aunt at the street food stall can also make fun of her in various ways, but she will not feel inferior! In various cities in the South, the atmosphere is just the opposite. When you talk to a stranger, the other person will be very wary, thinking that you are trying to scam money. Cleaning workers, migrant workers, etc. all work with their heads down. They have low self-esteem! It may have something to do with Confucian culture, group personality, economic differences, and dialect understanding! People from the Northeast will feel indifferent when they go to the South! And when southerners come to the Northeast, they will also feel uncomfortable being asked all kinds of questions! Everything has two sides. Both extroversion and introversion have advantages and disadvantages.
