The steps to change the CCB hierarchical management limit are as follows:

1. Log in to CCB online banking or mobile banking.

2. Enter the personal account page and find the "Account Protection" or "Credit Card - Limit Management" option.

3. On this page, you can view the current limit settings and modify these limits.

4. The single transaction limit, daily cumulative limit and total account payment limit can be adjusted as needed.

5. When modifying the limit, you may need to enter security factors such as transaction password, dynamic password card or online banking shield password.

6. After confirming the modification, click the "OK" button to complete the limit modification. In addition, if the user needs to lift the hierarchical protection limit, he can follow the above steps, but before setting a new password and confirming the new limit, he needs to ensure the security of the account.
