I want to call myself by my first name instead of my real name when I join the company. How does this affect you?

1. What is the purpose of hiding your real name? There is no windtight wall. When the company finds out, it will let you leave your job immediately because you are dishonest.

You must show your ID card when you enter the company from the beginning of the interview. Do you have any ID cards?

3. Welfare benefits can not be implemented, old-age medical insurance can not be insured, wages, housing provident fund, etc. Cann't cash it

In short, without an ID card, you can't move a step and accomplish nothing.
