King Wen of Zhou
The surname descended from the 15th son of King Wen of Zhou, Gao the Duke of Bi (畢公高), whose last name was Ji. During the Spring and Autumn period, an official of the Zheng kingdom, Feng Jian Zi was awarded the land of Feng (Henan province). The Jin kingdom besieged Feng and gave it to Wei Zhang Qing. Thus descendants of Wei Zhang Qing also have the last name of Feng.
