Zheng Keshuang
In 1683, the Kangxi Emperor of the Qing Dynasty ordered Shi Lang to lead a naval fleet to attack and conquer Tungning. Shi Lang and his fleet defeated the Tungning forces, led by Liu Guoxuan, at the Battle of Penghu. After the battle, the Tungning royal court split into two factions, with one advocating war and the other advocating surrender. The "war" faction was led by Zheng Dexiao (鄭得瀟), Huang Liangji (黃良驥), Xiao Wu (蕭武) and Hong Gongzhu (洪拱柱), while the "surrender" faction was led by Feng Xifan and Liu Guoxuan. Zheng Keshuang heeded Feng and Liu's advice. On 5 July 1683, Feng Xifan ordered Zheng Dexiao to write a surrender document to the Qing Empire. About ten days later, Feng sent Zheng Keshuang to meet Shi Lang. On 13 August, Shi Lang entered Taiwan and received the official surrender.
