Zheng Keshuang
Zheng Keshuang was survived by three sons: Zheng Anfu (鄭安福), Zheng Anlu (鄭安祿), and Zheng Ankang (鄭安康). However, all his sons died without issue; and so, Zheng Xianji (鄭咸吉), a first cousin once removed of them, was appointed as heir to Zheng Anfu. Zheng Xianji was the elder son of Zheng Ande (鄭安德) and a grandson of Zheng Keqiao (鄭克塙), and the latter was the youngest brother of Zheng Keshuang.
