If you must modify it, you must bring all kinds of proof materials to prove that the original name and the current name are actually the same person. It doesn't matter which bank you need to go to to to modify the information if you have a bank card. And if you want to modify the information, you must go to the bank where you opened the account for the first time, and you can't modify it across regions. Temporary or not. The bank will check whether your name and ID number are consistent in the "Check of Identity Information of Public Security System". If not, then you can't modify the information.
I hope it works for you!
