What is the difference between "stopping the procedure request" and "withdrawing the patent application" when applying for a patent?

Pause means to stop halfway. After the reasons for suspension are eliminated, the right can be restored and the patent application can continue to be examined. Withdrawing the patent application means that you don't want to apply, and the China National Intellectual Property Administration examiner is responsible for keeping it confidential, so when you want to apply again, you need to file a patent application again and pay the patent application fee.
