I don't seem to have heard of any regional differences. If you have an account (operating authority on Ping An website). Those who meet the requirements can do it directly online. If you have a telephone service password (which also requires advanced permissions), you can dial 955 1 1 and do it directly on the phone. If it really doesn't work, then find a salesman to do it for you, or do it yourself. For details, please consult customer service 955 1 1, otherwise you don't know your policy!
I hope I can help you!
