The archway is made up of these parts.
The first one is called a pedestal. Because the weight of the whole archway is on the pillars, in order to maintain the stability of the pillars, there must be a base to be fixed.
Second, there are pillars. The archway is built on several pillars. If this pillar wants to stand, it must have gripper stones. Stand the pillar as a pole with stones on both sides. It's different from the palace we built. Sometimes the palace disappears, but there is a pestle under it, which is the foundation of the pillar. This is not the case with the archway. There is a stone on one side holding the pole. Then there are Fang Liang, archway what to do, there are fangs, inscriptions, there are roofs. This is called a building, an archway, because it has a roof, and the top is a symbol of hierarchy.
Yellow glazed tiles have the highest grade. There are three floors above and four floors below. We call such an archway "the third floor, four pillars, and the seventh floor". There are seven buildings, and the tallest is nine. Originally, I wanted to design eleven higher buildings, so it was very rare in the whole country. Generally, the highest building of the feudal emperor was nine.
