This kind of shadow wall is located on the east and west sides of the gate, and forms an angle of 120 degrees or 135 degrees with the cornice of the gate. The plane is/\ shaped, so it is called "inverted splayed shadow wall" or "mountain shadow wall". When making this kind of inverted Chinese character screen wall, the gate should retreat 2-4 meters inward to form a small space in front of the gate, which can be used as a buffer for entering and leaving the gate. Against the backdrop of the anti-eight-character shadow wall, the house door is more profound, open and rich.
