Introduction to the back of the archway: The layout of the archway of the guild hall is a group of three pillars with three triangles. It has six pillars, five floors and three archways. It is in the shape of a chicken claw, so it is commonly known as the "chicken claw archway". This special planar column network structure enhances stability. In the center of each building, nearly two-meter-high round collars of "Towering Righteousness" and "Fragrance Will Last Through the Ages" are hung on the front and back sides.
