Zheng Keshuang
Zheng Jing returned to Tungning in 1680 from a failed campaign against the Qing Empire. In the same year, Chen Yonghua died after he was ousted from the political arena by his rivals, Feng Xifan and Liu Guoxuan (劉國軒). Zheng Jing died a year later in Chengtian Prefecture. After Zheng Jing's death, Feng Xifan allied with Liu Guoxuan, Zheng Cong (鄭聰) and others to slander Zheng Kezang in front of Queen Dowager Dong, Zheng Jing's mother. They claimed that Zheng Kezang was not Zheng Jing's biological son, and launched a coup to kill Zheng Kezang and seize power. Following the coup, a 12-year-old Zheng Keshuang was installed on the throne as the ruler of Tungning under the title "Prince of Yanping" (延平王). After his accession to the throne, Zheng Keshuang rewarded the officials who supported him in the coup by granting them nobility titles. He also gave posthumous honorary titles to his ancestors.
