The type of document to be submitted before replying to the audit opinion has been answered.
Specific operation, first of all, you should make clear the questions raised by the examiner, whether your original submission documents exist.
Where the questions raised involve the revision of the application documents, the original application documents shall be revised within the scope permitted by the Patent Law and its implementing rules.
If the questions asked involve questions that need to be explained, it is necessary to explain the questions raised by the examiner by using the existing known knowledge within the scope of the original application documents.
If you think the questions raised by the examiner are wrong, you need to explain your own views and argue with the examiner according to the patent law and its implementation rules.
I suggest that you find a formal patent agency to help you with the examination opinions, which can make the examination process of your patent application smoother.
