What does it mean that an application for a patent for invention is deemed to have been withdrawn after its publication?

The application for a patent for invention was published, but it was withdrawn due to various factors. If the applicant fails to submit the request for substantive examination or fails to pay the fee for substantive examination, it will be regarded as withdrawal, that is, the applicant has not submitted a written withdrawal application, but the inaction through some procedures will also lead to the abandonment of the patent application.
