What do you think of selling breakfast shops in Changchun? So I can learn technology.

Breakfast shops mainly look at the location and what other shops nearby do. You don't have to do the same thing as others. It is better to do complementary things. Together, there will be a market and no competitiveness. Breakfast is actually quite tiring. You need to get up early every day. If you are psychologically prepared, it is not recommended that you do it until you are ready. I can recommend the simplest, steamed stuffed bun shop. Now all the steamed stuffed bun shops you join are directly operated.
