Your question doesn't quite match your supplementary question. I will only answer your question. Then I'll give you some advice.

There are only two areas with the largest number of college students, Jiangbei Xueyuan Road and Jiangnan Xuefu Road. These two areas are concentrated areas of universities. But I don't think you can mix the market here. At least, it's hard for you to get a store.

In fact, any university, even high school, is enough to support your hot and sour powder shop. The following are some suggestions for you based on my experience. When college students leave the school, they must eat something casually when they are tired of dinner or shopping, or they are special. Most of the other time, they will choose the school cafeteria, and the items you choose are all things they are too lazy to eat in the cafeteria. I won't say more, you should know what I mean. Your project is more suitable for opening in commercial squares such as Wanda and Kaide. At present, this kind of project, especially in Harbin, is just a kind of fast food, which is suitable for people who go shopping. If you want to open it near the university, dare to ask if you are a college student, will you deliberately walk off campus for a long time just to eat hot and sour powder?

High schools are different. First of all, some high schools don't have canteens, so eating outside school is the only choice for students. Jianguo Street, for example, is a gathering area for junior and senior high schools. Moreover, the location is prosperous, and people also take the car. Even if students have a holiday, they can make a normal profit.
