吴佩孚
Ma Fuxiang, a member of the Zhili clique, signed a denunciation of the Anhui clique and its military arm, the Anfu Club led by Xu Shuzheng and Duan Qirui. The denunciation was circulated through a telegram called Paoting-fu, on 12 July 1920. The Zhili clique was led by Wu Peifu. At the time Ma was Defense Commissioner of Ningxia, Gansu. This led to the Zhili–Anhui War.
