If you are still at school, it is a little easier to change your name. After all, many things such as diplomas can be modified relatively easily.
If you have come to the society and worked, it's a little troublesome:
The first one: your diploma and so on should be revised back to school.
Second: Your insurance has to be revised by the insurance company.
Third: all your bank cards and passbooks should be revised, and some banks will ask you to show the certificate from the Public Security Bureau.
Like this, your ID card and social certificate should be revised one by one, and most of them should be reported to the newspaper for formalities.
Because of the age problem, the Public Security Bureau will deliberately prevaricate you, and finally tell the landlord an excuse. It is easiest to go to the Public Security Bureau to change the name (all my friends passed the customs after my recommendation): according to the family rules, it is not difficult to change into the genealogy. This Public Security Bureau will always let you go, so it is best to find a public security friend to help me talk.
