Why do you have to protect the road when decorating?

You should refer to the porch, but now you refer to the outside door of the hall, which is an area at the entrance of the room. It refers to the transitional space between indoor and outdoor in a house, that is, the buffer space for changing shoes and clothes indoors or walking from indoor to outdoor. Some people also call it a fighting room, a hall and a hall. Although the porch is small in size, it is frequently used and is the only place to enter and leave the house.

If you mean the other one, it's protective. Ensure safety.
