According to the Records of the Grand Historian, the ancestors of Chu came from the emperor Zhuanxu, who was the son of Chang Yi and the grandson of Huang Di. He is the son of Changyi, and the son of Zhurong. He served as a fire officer for the emperor and was named "Zhurong" by imperial decree. Later, when Chongli was executed for his crimes, his brother Wu Hui became his successor as fire officer and was still called Zhurong. Wu Hui gave birth to Lu Jian. He had six sons, Kunwu, Senhu, Peng Zu, Huiren, Cao, and Jilian, and mentions Jilian as the ancestor of the surname Chu, which descended from Chu. The Shiben. The Shiben of the Emperors. The six sons of Lu Jian are also recorded in the Six Sons of Lu Jian as Kunwu, Senhu, Pengzu, Huiren, Cao, and Jilian. In the late Han Dynasty, the scholar Song Zhi made a note stating that Kunwu was born from the surname of Ji, Senhu was born from the surname of S, and Hu was born from the surname of Food (a surname of Ji). Therefore, Lu, the son of Zhu Rong (Wu Hui), finally had six sons, who were born from the surnames of Hsi, S, Peng, Food, Cao, and Mi, which are the "six surnames of Zhu Rong". Later on, the Peng surname was divided into the surname of Vu, and the Cao surname was divided into the surname of Zhu and the surname of Pu. Therefore, the eight surnames of Zhurong were formed: 己, 斯, 彭, 秃, 먹용, 曹, 斟, 芈. There is also a theory that the surname of Ji was divided into the surname of Dong. See also
