What is the structure of the corner house in the building?

Corners are also called grinding corners. The first volume of "Yuanye" explains the grinding angle: "Grinding angles, such as temples, pavilions, rat horns and pavilions, is absolutely useful." Single buildings, such as the large wooden structure at the top of the temple and the rest peak, the turning part of the corridor of the group building, and the turret of the castle building, whether simple or complex, belong to the turret.
