Why is the language ability of the northeast people so strong?

This is related to personality. There are fewer introverts in Northeast China. Generally outgoing. For example, in Changchun. Walking on the road, you can chat with street cleaners and sanitation workers casually, and it is common to pass cigarettes to strangers. And the cleaner will take the initiative to talk to you about today's weather! Aunties at street food stalls can also make fun of all kinds. He won't feel inferior! In southern cities, the atmosphere is just the opposite. When you talk to a stranger, the other person will be very alert. He thought you were going to cheat money. Cleaners, migrant workers and so on all bow their heads to work, which makes them feel inferior! It may be related to Confucian culture, group personality, economic differences and dialect understanding! Northeasters will feel indifferent when they go to the south! Southerners who come to the northeast will also be asked questions about the east and west. Everything has two sides. Both extroversion and introversion have advantages and disadvantages.
