How about opening a county-level jewelry store?
A county town with a population of 80,000 can also have 6-7 jewelry stores, depending on your consumption habits. The main jewelry consumption places in rural areas and counties are prefecture-level cities or counties. The most direct thing is to investigate the sales of the jewelry store you open. You can befriend people in the store first, then make friends, invite others to dinner, and get to know the real sales situation.
