Song Jiaoren
Cai E was Governor of Yunnan from 1911 to 1913. After the revolution Cai gained a reputation as a strong supporter of democracy and of Kuomintang politician Song Jiaoren. Following Song's assassination by Yuan Shikai, and Yuan's subsequent assumption of the presidency of the Republic of China, Yuan had Cai removed from office and eventually held under house arrest in Beijing. Tang Jiyao replaced Cai E as Military Governor of Yunnan in 1913.
