The reasons are as follows:

1. The operating costs of breakfast shops are relatively high, including rent, raw material procurement and labor costs.

2. Breakfast consumption habits and cultures vary from region to region, and the demand for breakfast consumption in the region is relatively low. The number of breakfast shops will be relatively small.

3. In the catering industry, especially in the field of breakfast, the competition is fierce. Some shops will quit the breakfast market because of too much competitive pressure.
