Abstract: This article explores oversew sources in Japan and Korea and rare historical materials in China，to elucidate a series of secret events that occurred after the Qing court promulgated the Pacification Edict on the Revolt of the Three Feudatories. For example，the rebel lewder Geng Jingzhong was actually executed after the promulgation of the edict，and it was the minister Songgotu and others who protected and prolonged his live. Based on historical sources，it was said that Shang I}exi in fact supported Shang Zhixin’s actions. In order to destroy the evidence，the Kangxi emperor executed numerous officials who participated in the purge of Shang Zhixin. This article thus makes great revisions and supplements to current conclusions on the research of the Revolt of the Three Feudatories.
