Why should the hotel periphery be separated from the fence?

The guardrail placed at the entrance of the hotel is an isolation guardrail to isolate some exhibits and prevent them from being damaged by personnel. According to the relevant inquiry information, the isolation hotel should have warning isolation guardrail, and irrelevant personnel are prohibited from entering and walking. Before the isolation hotel is put into use, it must go through the joint acceptance of district-level fire control, safety supervision, disease control or health supervision.
