鄭克塽
Zheng Jing and Chen Yonghua died in 1680, after which Feng Xifan gathered his supporters to kill Zheng Kezang and install Zheng Jing's second son, Zheng Keshuang, on the throne. In 1683, when Zheng Keshuang surrendered to the Qing dynasty, Feng Xifan was granted the noble title "Count Zhongcheng" () by the Kangxi Emperor. Feng's daughter married Zheng Keshuang and bore Zheng a son, Zheng Anfu ().
