The Zheng clan of Xingyang (simplified Chinese: 荥阳郑氏; traditional Chinese: 滎陽鄭氏) was a prominent Chinese clan, chiefly based around Xingyang county (modern day Kaifeng, Henan).
Tracing their origins to the rulers of the State of Zheng,[1] they became highly prominent in government during the Northern and Southern dynasties, where they became one of the "Four Clans" in Northern Wei, and also during the Tang dynasty.
[2] The Zheng clan of Xingyang traces its descent to the fall of the State of Zheng to the State of Han in 375 BC.
[3][1] The clan was first established in Xingyang county by Zheng Dangshi [zh], son of Zheng Jun [zh], a general who served under Xiang Yu.
The Zheng clan first became prominent in the Northern and Southern dynasties period as officials in Northern Wei, beginning with Zheng Xi (426–492).
