Why can't Lv Yun Hotel Management System delete the guest's historical information?

Because the hotel registration is to be uploaded to the Public Security Bureau, the hotel has no right to delete historical information.

The personal information entered by Lv Yun Hotel Management System is combined with the floating population data of the public security system for a period of time, and even the front desk personnel have no right to delete the registration of the public security system. So it can't be deleted in a short time, but after a period of storage, the system data will be emptied regularly, but the data of the public security system will not be emptied. Large hotels are connected with public security information network. Small hotels generally have a hotel customer management system to register hotels, and the front end of the management system is also made by the public security network supervision brigade, which is basically cleaned once every three months.
