Door railing of family courtyard

The gatehouse of family courtyard is a unique part of traditional architecture in China.

In the past, people thought that ghosts would visit their houses constantly and build a wall to block the path of ghosts. Because it is said that children can only walk in a straight line and can't turn.

Another view is that Zhaobi is a unique architectural form in China influenced by Feng Shui consciousness, which is called "shadow wall" or "shadow wall".
