According to the query of OK Software Park, the micro-policing app is a mobile phone application launched by the micro-policing platform, which integrates the functions of consultation, handling affairs, reporting and complaining. According to the query of Baidu Youjia. com, the driving school file cannot be cancelled on the mobile phone. In most areas, students need to go to the vehicle management office by themselves.

1. Go through the cancellation formalities at the vehicle management office where the driving school is located with the original and photocopy of the ID card;

2. Fill in the form distributed by the staff;

3. Hand over the handwritten "I voluntarily quit the C-driving business", signature and contact information to the staff;

4. If it is a driving school, you can provide a copy of your ID card and handwritten "I voluntarily quit the C driver's license business", signature and contact information, and hand it over to the driving school staff for file cancellation procedures. It can be seen that Tianjin Micro Police cannot return the driving school files.
