陈炯明
When Sun Yat-sen, leader of the Chinese Revolutionary Party, attempted to re-establish himself in Guangzhou in 1917, warlord Lu Rongting reluctantly supported him for a few years. After Sun split from the Old Guangxi Clique over allocation of troops, he attempted to strip Cen Chunxuan (aka Tsen Chun-Hsuan or Sam Sun-Suen), one of Lu's most important allies in Guangdong, of some of his troops in order to assign them to the more apparently loyal Chen Jiongming, a local Guangdong warlord who had sponsored Sun. Sun Yat-sen then directed Chen Jiongming to attack Lu Rongting and the other Guangxi warlords. In October 1920 Chen captured Guangzhou and drove the Guangxi warlords out of Guangdong.
