For the following reasons, this information is not available after re-registering the Tian Tian Fund after canceling the account:

1. Complete cancellation: If you completely cancel on the Tian Tian fund platform, all information before re-registration will be cleared, including investment records, bank card binding and other information. This means that you need to fill in all the relevant information again.

2. Account Freezing: If your account is frozen, you may need to unfreeze it to restore access to previous data. If you can unfreeze your account, your previous investment records and related information can still be accessed after re-registration.

3. Partial cancellation: If your account is only partially cancelled, some information may still exist after re-registration. You need to check the account pages before and after account cancellation to know the specific information that needs to be kept.
