Can the user information of an e-commerce platform be saved after the user proposes to cancel the account?

You can't. Account cancellation means that you no longer use the account, and the personal information registered and submitted by the account will be deleted by the system, because it is not safe to save personal information in the cancelled account. After the account is cancelled, you can apply for re-registration. At this time, you can't log back into the original account, because the personal information of the original account has been deleted by the system, but you can rest assured that it is very safe.
