1. Confirm the wrong records that need to be corrected: First, carefully check the wrong records in the account book to determine the specific items that need to be corrected. For example, it may be the wrong amount, date or account name.
2. Cross out the wrong record: After the wrong record is found, draw a straight line on it, indicating that the record will be cancelled.
3. Write down the description of the modification: under the crossed-out error record, write down the reason and description of the modification. For example, if it is a corrected amount, it can be written as "the corrected amount is wrong, it should be XX yuan".
4. Add the correct record: re-record the correct information under the correction description. For example, after correcting the wrong amount, write down the correct amount.
5. Write down the reversal voucher number: In order to track the reversal operation, you can assign a unique voucher number to the reversal operation for searching when necessary.
6. Signature and date: Write your signature and date at the end of the correction record to confirm the correction operation.
Please note that the correction operation of handwritten bank account books may be different depending on the account book template used by banks or individuals. It is best to contact the bank you use or consult the relevant bank regulations to obtain more accurate operation methods. In addition, with the development of technology, many banks have realized the electronic ledger system, and the reversal operation in this case may be different.
