Zhili–Anhui War
In Shanghai, Sun re-organized the Kuomintang to oust the Guangxi junta from the Southern government. The military governor of Guangdong, Chen Jiongming raised 20 battalions from Fujian. In 1920, Duan and the northern parliament was ousted after the Zhili–Anhui War. Lu and Cen used this as a pretext to explore unification with the Zhili clique. The KMT denounced these secret negotiations and the southern parliament moved to Yunnan in August and in Sichuan from September to October. Tensions between the Yunnan clique and the Guangxi clique allowed Chen to invade on August 11 in the Guangdong–Guangxi War. Chen Jiongming expelled the Guangxi clique from Guangzhou allowing Sun to return by the end of November.
