Chen Jiongming
In April 1922, Chen Jiongming was discharged when he refused to embark on a “Northern Expedition”; Sun's attempt to defeat the Northern Army in order to unite the country. On June 16, 1922, unable to accept Sun Yat Sen's leadership, Chen Jiongming's subordinate Yip Ku 葉舉 ordered the arrest of Sun Yat Sen. Luo Xian Xiang was tasked to carry out this order. However, the plan was leaked and Sun escaped to a warship 永豐艦; from where Sun rallied his base. In history, this was known as 6.16 Incident. After Sun's departure, Chen Jiongming returned to govern Guangdong Province.
