Origins
The Ji-Surname Origin
According to a note in the Zheng Tongzhi, one origin is from the Ji surname: Gongzi Xi, son of Duke Mu of Zheng, had the style name Zihan, and his grandsons Han Hu and Han Bo adopted their grandfather's style name as a surname. The source presents this as one origin, not the sole origin.
