You can initiate the transfer custody business to transfer your fund share from one bank to another.
The premise is that the other bank also sells funds on a commission basis.
There are two ways to transfer custody: one-step transfer custody and two-step transfer custody. Either way, you must go to the other bank to register a capital account. If it is a one-step transfer custody, you can go to the current bank counter to handle a transfer custody. If it is two-step transfer custody, you have to go to the other bank to do two-step transfer custody.
In addition, if your fund account has a balance, you can't close it.
