What is the sign that the entrance of the shop can only be entered?

There are signs that. The entrance sign of a store is a sign used to indicate consumers. It means that people are only allowed to enter the store from the marked position, but not allowed to leave from the store exit. This sign is mainly to maintain the management order in the mall, prevent consumers from leaving the mall directly through the exit, and help businesses control the flow of people. At the peak of consumption, using this sign can avoid crowding and confusion and ensure the safety of consumers and businesses. It should be noted that consumers should strictly abide by the provisions of any sign marked "No Entry" to avoid unnecessary disputes or inconvenience.
