The steps in front of the six or seven officials shall not be higher than the second level, the steps in front of the five senses shall not be higher than the third level, and so on, but at most they shall not exceed the eighth level. More than eight is nine, nine is the pole of the number, representing the vertex, and no one can use it except the emperor. With the promotion of officials, the front steps will gradually increase.

The circle is a military attache, symbolizing the war drum; Civil servant square, in the shape of inkstone. The size of the "household pair" is directly proportional to the size of the official goods.
