As far as I know, Chongqing is a warm and cheerful city, a place full of fireworks and human feelings. If you feel out of place in this city, you don't have to think so. People's impression of a city is what most people feel. There are many people who prove Chongqing's enthusiasm, and there are also many people who are not enthusiastic and cheerful. In my opinion, if you are not an extrovert, you don't have to force yourself into the social circle you don't like, just do what you feel comfortable with and make friends you like. In the face of fear, it is better to think than to act. It doesn't matter if you are wrong, at least you don't regret it.
