Let the guests use it to shelter from the rain.

The porch refers to a passage with a roof and balcony, which protrudes in front of the building. Such as doorways, rain shields, awnings, etc. A long road that people walk in front of a room, at the entrance of a building, there is no door, there are walls on three or two sides, and there is a wooden board (or a superstructure) on the upper part.

The parking place in front of the hotel is called porch. The entrance is divided into full concave type, half concave and half convex type, full convex type and so on.
