the answer from the friend upstairs is so long! ~
I think there is still a market. The key is to be distinctive and authentic.
Some of my Northeast classmates often take me to some authentic Northeast restaurants, and business is booming! ~ but most of them are eaten by the northeast people, and there are quite a few Nanchang people. For example, I especially like to eat stew in the northeast.
I think if you really want to drive well, you should first visit Nanchang for a period of time. You can open a shop that focuses on soup shops and combines a variety of special snacks.
You can also apply to a soup shop as an apprentice first.
Don't set up any franchise stores either. It's not like this soup shop needs high technology.
Make your own characteristics!
