According to the fund law, every open-end fund has a custodian bank. The main responsibility of the fund custodian bank is to supervise and verify the business of the fund manager to ensure that the asset management institution will not illegally operate the assets in the fund account.
The popular saying is that the shares, bonds, cash and other fund assets of Dacheng Jingyang Fund are placed in the special account of Dacheng Fund of Agricultural Bank of China, which is supervised by the Agricultural Bank. Dacheng Jingyang Investment Management Team only has operation authority and can't do anything else.
