Can I change my driver's license at Taiping Town Post Office in Conghua District? how much is it?

I can't. Postal departments do not have the qualification and authority to renew driving licenses. It is a national bureau managed by the Ministry of Transport of the People's Republic of China and a government department that supervises the postal and express delivery industries. The driver's license needs to be applied to the public security traffic management department, so it is not allowed to renew the driver's license at the Taiping Town Post Office in Conghua District. A driver's license is called a motor vehicle driver's license, also known as a "driver's license". According to the law, motor vehicle drivers need to apply for a license.
