First make a general positioning according to your own situation, such as how much you want to invest,

1, choose features, not popularity: popularity may come from a TV series and a celebrity's endorsement, but it can't stand the test of time. Characteristics are the foundation of survival.

2. Choose a small and beautiful restaurant instead of a large and comprehensive project: the gross profit of a small and beautiful project will be higher; Large and comprehensive projects have high cost, limited income, much smaller risk ratio and much more beautiful.

3. Choose popular projects instead of niche projects: popular projects have a large audience, and niche projects are often difficult to make a profit.
