What should I do after submitting an application for examination of patent substance?

After submitting an application for substantive examination of a patent and paying the substantive examination fee, the Patent Office issues a notice of substantive examination, and the patent application enters the substantive examination stage. You can go to China National Intellectual Property Administration's website, which has a payment information inquiry column and a notice information inquiry column. You can inquire about relevant information, or you can inquire about your own patent application by email.
