耿精忠
Li was a native of Anxi County, Fujian Province. In 1670, he was promoted to the rank of "jinshi" and moved to Beijing, leaving his brother Li Guangpo behind to look after his family. Li's career prospects improved when the Emperor pacified Fujian and acted on Li's suggestion to defeat Wu Sangui. He also helped defeat Geng Jingzhong, persuading his friend Chen Minglei to work as a spy in Geng's camp. Later in life, he was responsible for planning Shi Lang's conquest of Taiwan. During the course of his life, Li held various court positions, including Chancellor of the Hanlin Academy, Governor of Zhili and Grand Secretary, and positions on the Board of War, Board of Civil Service and the Board of Public Works.
