In the mode of buying jewelry to earn commission, even if new people join, there is no guarantee that it will not collapse. This is because this model itself has certain risks. Here are some possible reasons for the crash:

1. Product quality problem: If the quality of the products sold is not good, or there are too many complaints about returning goods, the company's reputation will be damaged, which will affect the company's operation and sales.

2. Market risk: the market changes are unpredictable. If the market changes lead to a decline in the company's sales or profit margin, it will have an impact on the company's operations.

3. Management: If the company is poorly managed or has loopholes in internal management, it will affect the company's operation and management. For example, problems such as chaotic management, high turnover of personnel and irregular financial management may all lead to the closure of the company.
