There is a wall outside the gate, which is called a screen wall or a screen wall.
Zhaobi and screen wall are unique parts of traditional Han Chinese architecture in ancient China. They are wall-type auxiliary buildings of ancient Chinese courtyards. They are generally located outside the door facing the gate, or in the courtyard facing the gate or hall. at. It was especially popular during the Ming Dynasty. In the old days, people believed that ghosts were constantly visiting their houses, so they built a wall to block the ghosts' coming. Because it is said that the imp can only walk in a straight line and cannot turn. Another theory is that the screen wall and screen wall are a unique architectural form in China influenced by Feng Shui consciousness, which is called "screen wall". Because their forms are roughly the same as screen walls, with only differences in shape and decoration, many people confuse the two and think that a screen wall is a screen wall, or simply think that the south is called "zhaobi" and the north is called "yingbi". In fact, there is a clear difference between the two. The name is different because of the different role this wall plays in construction. For example, in ancient times, Fusi (also called Fusi, Zhensi, Fusi, and Shelter) was a screen set up outside the palace gate in ancient times. There were holes on it, shaped like a net, to guard and prevent unexpected events, and it was engraved with clouds and gas. , insects, beasts and other patterns. In the Han Dynasty, the screen was called "桴思", which was the emperor's external screen. When ministers came to the screen, they would repeatedly think carefully about matters related to the emperor. It mainly plays the role of blocking the line of sight from the outside to the inside. The purpose is to hide the building behind the wall, so it is called the hidden wall, and later also called the screen wall. On the contrary, the purpose of a wall that blocks the view from the inside out is to cover the building inside the wall, so it is called a cover wall, and later also called a screen wall.
