The source of funds for public welfare funds is mainly donations from people from all walks of life or enterprise organizations. As for the appreciation and preservation of funds, the main ways are to deposit them in banks regularly or buy government bonds, and not to make other market venture investments. After all, the function of the public welfare fund is public welfare rather than profit. The market participation of the public welfare fund is very low, that is, infrastructure construction, necessities procurement and so on. So there is no balance between the market and public welfare.
