2. It comes from the surname of Zi, which originated in Shang Dynasty and is the descendant of King Chengtang. The surname of Zi is Fan Shi in history. According to Zuo Zhuan, Shang Tang's descendants formed seven clans, namely, Tao, Shi, Fan, Fan, Kun, Ji and Zhong Kui after the middle of Shang Dynasty, among which Fan was the surname, and the descendants have been inherited. After the demise of Shang Dynasty, Zhou Wuwang placed seven families of adherents of Shang Dynasty under the jurisdiction of Qi State, so before and after the Warring States Period, Fan's surname was mostly in Qi and Lu areas. Fan Chi, a disciple of Confucius, is a descendant of Fan, one of the seven merchants.
