What is the role of the rural entrance wall? From the perspective of geomantic omen, are porch walls and walls connected?

This entrance wall is called shadow wall or shadow wall. This small house can be connected to the wall. Big houses are usually separated. Shadow wall, also called zhaobi, or Xiao wall in ancient times, is a kind of wall used to block the view of traditional buildings in China. In the past, people thought that ghosts frequented their houses. If it is the soul of one's ancestors, it is allowed to go home, but if it is a lonely ghost who sneaked into the home, it will bring disaster to himself. If there is a shadow wall, ghosts will be scared away when they see their own shadow. Of course, the screen wall also has its function, which is to block the line of sight of outsiders, even if the door is open, outsiders can't see the house. The screen wall can also set off the atmosphere and increase the momentum of the house.
