The title system is closely related to the patriarchal clan system, and the initial recipients are only the royal family. "Zuo Zhuan" Zhao Gong twenty-eight years: "In the past, the king of Wu was a businessman, and his brother country had five people and his country had forty people, all of whom raised relatives." During the Warring States Period, after Shang Yang's political reform, the State of Qin abolished the royal title and established the system of 20 th rank title to reward meritorious deeds (mainly military achievements).
From the highest 20 to the lowest one, the order is: Che Hou, Guan Neihou, Da Shu Chang, Zhu Che Shu Chang, Da Shang Zao, Shao Shang Zao, You Geng, Zhong Geng, Zuo Geng, You Shu Chang, Wu Fu, Gong Cheng, Gong Fu, Guan Fu, Doctor, Bu Geng and Yao Da. After the Western Han Dynasty, royal titles and meritorious titles coexisted until the Qing Dynasty.

Title has something to do with official position. The Duke and Marquis granted by the Western Zhou Dynasty were vassals of the Zhou Emperor and monarchs of feudal countries, and the officials and the nobles were one. Since then, the general trend has been the gradual separation of officials and nobles, but there are still exceptions in some periods. In the Western Han Dynasty, the Western Jin Dynasty and the early Ming Dynasty, the imperial clan kings had military and political power in feudal countries, and their power gradually expanded, which successively led to the "Seven Kingdoms Rebellion", "Eight Kings Rebellion" and "Jingnan Rebellion", which seriously threatened the imperial power. Titles in other periods were only honorary titles, which were graded according to their close relationship with the emperor (royal titles) and their contribution (meritorious titles).
In ancient times, Jue Lu was often summoned repeatedly, and he would be rewarded after receiving the title. In the Western Zhou Dynasty, the duke and marquis were the monarchs of the feudal country, and all the financial revenues of the feudal country belonged to them. However, the duke and marquis must bear the obligation of guarding the territory, paying tribute tax and making pilgrimage to the Zhou Emperor. In the future, the title will have a certain food city, but it will not be collected by itself, but will be distributed by the dynasty. Later, the food city became a hollow reputation. Only by adding several so-called "grain seals" before the title can we enjoy the corresponding household seal tax or get some kind of seal from the state.
