1. Investors first transfer the deposit to their corresponding bank settlement account, so that the balance of the fund account is zero.

Redesignate a new depository bank, sign a depository agreement, and finally bring relevant documents and the depository agreement signed by the sales department of the securities company, go through the confirmation procedures of the depository bank at the counter of the bank outlet, establish a new depository relationship, and open the third-party depository transfer function.
