The professional quality of the male protagonist

...Xin and q...q are commonly used software for communication on the Internet, and you usually have a registration when you log in from a different place.

These things should be approved by Zhang Xuan's superiors if they apply for investigation, but after the superiors' approval, and then the investigation by the crowd in their police station, it may take a month or two to complete the process.
