In Chinese mainland and Taiwan Province Province, Dou's surname is not among the top 100. The origin of Dou's family is ancient, and its distant ancestor began in Xia Dynasty. Is a descendant of Dayu. Originated from the Yu family. After the Xia monarch was killed, the princess escaped from the sinus and returned to her family, giving birth to a posthumous child, Shao Kang. Later, Shao Kang restored the Xia Dynasty, which was called "Shao Kang Zhongxing" in history. Shao Kang's two sons, Zhu and Long, still live in Youliang, so they take Dou as their surname. Later, he ascended the throne and became the next king of Xia. Development and evolution: The ancient minority Di people (distributed in present-day Shaanxi, Gansu and Sichuan) also took Dou as their surname. In the Han Dynasty, a queen, Dou Taihou, was born in the Dou family in Guanjin, Qinghe. She is Heng's wife and the mother of Jing Di Liu Qi. When she was in power to Emperor Wu of the Han Dynasty, the Doushi family in Qinghe flourished and gradually formed a noble family. In addition, in the process of development, Dou's family gradually formed two counties in Henan, and developed into a famous family in the local area. Therefore, the surname Dou is called the King of Fufeng (Emperor Wu of the Han Dynasty listed Youfufeng as one of the three assistants). In Wei Dynasty, the Three Kingdoms changed to Fufeng County. In today's west of Chang 'an County, Shaanxi Province), King of Henan (Emperor Gaozu set up a county. In today's Luoyang City, Henan Province), Qinghe King (Gao Han's hometown county). It is equivalent to Qinghe in Hebei to Linqing in Shandong today).
