When the famous rebel Wu Sangui died in October 1678, Kangxi had his corpse scattered across the provinces of China. Wu Sangui's grandson Wu Shifan took over Wu's troops and continued the battle. The remnants of his armies were defeated soon thereafter in December 1681 and Wu Shifan committed suicide; Wu Shigui's son-in-law was sent to Beijing with Wu Shifan's head.
