Why can't I find the legal status of the patent?

As the patent has not been made public, the legal status of the patent cannot be found. According to relevant information, we can't see the status of patent application before the patent is published. According to the provisions of China's patent law, the patent application review process is that the applicant submits a patent application to China National Intellectual Property Administration, and China National Intellectual Property Administration issues a notice of acceptance to the applicant, then enters the preliminary examination, and then announces it after the preliminary examination is passed.
