How long does it take for the mall security guard to patrol the store at night to be considered illegal?

It is illegal for mall security guards to patrol the store 1 hour at night. Specifically, the business hours of shopping malls are usually from 10 in the morning to 9: 00 in the evening or 10 in the evening. Security guards should patrol the shops after this time period, preferably after the shops are closed, so as not to affect merchants and consumers. If security guards enter the store during business hours, it may be regarded as interfering with the normal business and activities of merchants and consumers and violating the rules and regulations of security work. At the same time, if the security guards stay for a long time before the store closes, it may also cause property losses in the store, so the time for security guards to patrol the store needs to be limited to a reasonable range.
