First go to the industrial and commercial bureau to change the personal name and address on the business license. After the change, re-engrave the official seal. Then, go to the Quality Supervision Bureau to make changes with the changed business license (copy), the copy of the ID card of the person in charge, the copy of the ID card of the manager, the official seal and the original and copy of the code certificate. Finally, go to the tax bureau and bring a copy of the changed business license, code certificate and tax registration certificate. It's almost the same as what you brought at first. Now you can bring the modified one.
