The court should have a clear theme. For example, if you sue an individual, you can't go to the public security bureau to check the household registration information. Just have a clear address. So have a clear target.
The second question, I estimate that the files of local industrial and commercial bureaus are managed separately, and there is no ability to inquire at the higher level or at the same level. This should be limited by technical conditions, and so is Beijing.
To solve the problem, I suggest you call the local government hotline, the mayor hotline and so on. The problems assigned by the government are given priority by all functional departments. For example, there is a non-emergency rescue service center in Beijing-12345.
