徐樹錚
Lu was murdered in Tianjin by Fengtian clique members Xu Shuzheng and Yang Yuting. An opponent of Duan Qirui and the policies of the Anhui clique, Lu was shot in an ambush a day after arriving in Tianjin from Shanghai. His death further strained relations between the Zhili and Anhui cliques, eventually leading to the Zhili–Anhui War of 1920. In 1925, Feng Yuxiang, his relative, killed Xu in revenge for Lu's murder.
