"New Book of Tang" Volume 46 "Hundred Officials Chronicles One" summarizes the positions and grades of the Tang Dynasty in this way: The official divisions are province, platform, temple, prison, guard, and government, each of which belongs to its subordinates and is positioned according to their respective duties. In the Tang system, there were honors, ranks, officials, and nobility. Nobles are used to determine one's superiority and inferiority, officials are used to classify duties, ranks are used to describe labor, and honors are used to describe merit. The four are not mutually exclusive. There are officials and those with lower ranks but honors and higher ranks. There are also those with honors and lower ranks but officials and higher ranks. In the Song Dynasty, if the official rank was high and the rank was low, it would be called "Xing"; if the rank was low and the official was high, it would be called "Shou"; if the official had the same rank, there would be no word "Xing" or "Shou". The current system is only based on the official position, and if it is an official, the honor, rank, and title will follow, and there is no need to repeat the meaning of labor and merit. As for the Qing Dynasty, a rather simplified scattered rank system was implemented, from the first rank to the ninth rank and eighteen ranks.
