In ancient China, the titles were male, hou, bo, zi and male. The Zhou Dynasty was divided into five levels: the public, the Hou, the Bo, the Zi and the public, all of which were hereditary. The fief was called the state, and sovereignty was exercised in the fief. The vassal state placed titles such as Qing, doctor and scholar, while Chu placed titles such as Gui and Si. Both Qing and doctor have fiefs, and they can also exercise sovereignty over fiefs, only under the orders of governors.

During the Warring States period, the vassal states generally abolished the feudal system of Doctor Qing, and implemented the county system, resulting in the emergence of titles such as Tong Hou and Jun, which were different from those of the former Doctor Qing. These new titles all had food cities of different sizes, but they could not be inherited.

Chinese knighthood, also known as knighthood and Spyker, is the appellation of the ancient royal family and nobility in China, which is used to express the level of status and rights. Spyker began in Xia and Shang Dynasties and ended after the founding of the Republic of China.

"Tongdian. Official. "Titles" records that there were five titles from Yaodi to Xia Dynasty: Gong, Hou, Bo, Zi and Gong. There were three titles in Shang Dynasty: Gong, Hou, Bo, Childless and Gong. What is the fact? There is no physical data to support it.

The business departments recorded in the literature include Hou, Dian, Gong, Wei and Bang Bo, all of which belong to the "foreign service princes" besides Wang Ji. Oracle Bone Inscriptions in Yin Ruins shows that "many parties" outside Yin State are often the enemies of Shang State. Their princes are called "Fang Bo" or "Bang Bo", such as Ren Fangbo, Fang Qiangbo, Yu Fangbo and Zhou Fang Bo.

The princes on the border of Yin and State were called Hou and Bo respectively, such as Qi Hou, Gou Hou, Jing Bo and Song Bo. They were the vassals of the Shang kingdom, and they were often ordered by the Shang king to conquer many parties, and the Shang king often sent troops to help them. The difference between Fang Bo and his titles reflects the close relationship between these governors and Shang Wang. Some scholars believe that "Tian", "Zi" and "Male" in Oracle Bone Inscriptions or inscriptions on bronze in Shang Dynasty are also appellations, and there is no conclusion at present.
