The foundation can carry out business activities for the purpose of maintaining and increasing the value of the fund, and can also carry out charity performances, charity sales and other activities for raising funds. The proceeds from these activities should be used for public welfare undertakings and cannot be distributed internally; When the foundation is terminated, the property of the foundation cannot be returned to the donor and must be transferred to other non-profit organizations. Therefore, these business activities of the foundation are still for the purpose of public welfare and do not affect the non-profit of the foundation.
