1. Epidemic impact: The COVID-19 epidemic broke out all over the world, which affected the industry to varying degrees, especially the catering industry. Many businesses selling glutinous rice stopped selling because of the epidemic or changed their business strategies.

2. Poor management: Merchants selling glutinous rice will encounter many problems in the course of operation, such as insufficient supply of ingredients, large price fluctuations and too many competitors. Merchants can't solve this problem and will choose not to continue selling glutinous rice because of poor management.
