The ancient monarch was just a title, representing a certain aristocratic status, not an official position. The title of monarch itself cannot manage affairs, but it does have a certain imperial status. There are also some differences in the rank of monarch, such as prince and county king. Generally, the prince only seals the emperor's first relatives, and the county king is one level lower than the prince and only seals the emperor's cousins. However, individual courtiers who have made great contributions will also be crowned as kings, such as Guo Ziyi in the Tang Dynasty and Yue Fei in the Song Dynasty. The system of sealing kings has changed greatly in various dynasties. For example, in the Tang Dynasty, all kings were vassals, such as the king of Qin, the king of Lu, the king of Yong and the king of Qi. The word king is the county king, such as Huai' an king and Jiangxia king. Although the title of a monarch is not an official position and has no substantive jurisdiction, everyone who is a monarch has a certain official position. Even the monarch has a starting position, that is, when the prince was crowned king in the north, he was given a lowest position according to his status level, and then he relied on himself. Those with strong ability can continue to climb, and those with poor ability also have the minimum power guarantee. Some members of the royal family who have committed serious crimes may also be removed from office. At this minimum, different dynasties and different grades of princes are different. Take the Tang Dynasty as an example. The starting official position of a prince is Zhengsipin. In other words, the monarch is a title, not an official position, but people who are monarchs often hold official positions. The size of the official position has nothing to do with his sovereign status, only the minimum value, and the position of a person with great ability can be infinite. For example, before Emperor Taizong Li Shimin ascended the throne, he was the King of Qin (Prince) and the second son of Tang Gaozu, Tang Gaozu. At most, he held seven official positions, from level 1 to level 4, both civil and military. And many of his brothers who have no special skills are only four-level officials at the very least. In ancient times, the system of sealing the king and the system of official positions were very complicated, and the regulations of each dynasty were different.
