Princess is the title of royal women in ancient feudal society of China. Princess princess evolved from the word princess princess. The county king began in the Eastern Han Dynasty. Generally, the rank of imperial women is princess, but a few are princess. After the changes of the times, the princess has different identities, such as the daughter of the emperor, the daughter of the crown prince, the daughter of the king, the daughter of the emperor and the daughter of the prince. It was not until the Tang Dynasty that the princess became a specific title and was the daughter of the Crown Prince.

The word "princess" originated from Liu Yiqing, king of Linchuan in the Southern Song Dynasty, and was compiled by Shi Shuo Xin Yu Yuan Xian. Huan Xuan Wu (referring to Huan Wen) took Li Shimei as his concubine, and Southern Liang Liu Xiao quoted "Jealousy": "Uncle Huan Ping took Li Shimei as his concubine, and the monarch (Nankang monarch) was fierce and jealous." The princess here refers to her daughter Sima Xingnan, which is the abbreviation of the county king.
