Feng appeared as early as the Eastern Zhou Dynasty. According to Yuan He Shi Dian and Guang Yun, Feng is the ancestor, which can be traced back to 15 Zibi. His descendants were sealed in Wei, and their descendants ate in Fengcheng. So this descendant took the city as his surname, that is, Feng. However, the book Shiben's, the earliest record of surnames, said that Feng was "behind Dr. Zheng and Feng Jianzi". Feng Jianzi was from Zheng Jiangong in the late Spring and Autumn Period. It is said that he is well-read and can make important decisions. At that time, Zheng had to deal with princes in everything, and many important matters had to be discussed with him before making a decision. Because our capital is in Xinzheng, Henan, the Feng family is from Xinzheng.
