Patent, how to contact the examiner? Where can I find the telephone number of the examiner Sha Xu?

The general examiner thinks it is necessary to contact the applicant by telephone, and will write his own contact number in the review opinion. If he doesn't write, it means that he thinks the notice has made it clear.

I wonder if you can call the customer service number of the patent office upstairs. Anyway, I know that examiners in the same department of the patent office usually have a detailed contact phone list with the examiner's phone number on it. If you have friends in the bureau, you can ask them to inquire for you.
