Zhaoqing Business Department of GF Securities wants to restore my account.

If you forget your account number, just get it back in official website. Generally, at the door of the online business hall, click "Forgot Account" to get it back.

If the account has been cancelled, it can't be retrieved, so you can only open a new account. Go to the sales department to open an account, or open an account online with a computer and mobile phone.
