The employer will verify whether the company listed on my resume exists. Have I ever worked in this company?

No, there are millions of enterprises and companies in China. Some companies may ask you to show your previous company's certificate. Usually I don't care about these things. I ask about your work experience, just to get to know you roughly. If you want to brag, be prepared and don't be asked.

Generally speaking, in a simple position, you just said to be patient and not to jump ship. You can even say that you are finished without any planning.

If you are a sales or management worker, it is better to write something ambitious.
