1. The competition is fierce: there are tofu stalls or stalls that attract customers around, and people will choose to buy food elsewhere instead of iron tofu stalls. The fierce market environment has led to no interest in iron tofu stalls.

2. Improper location: The location of the booth is very important. The location of the iron plate tofu stall is inconspicuous, or it is far away from the place with large traffic, which will lead to no one buying it. Choosing a suitable location is very important to attract customers.
