У Пэйфу
As Wu Peifu retreated to Tianjin, he concentrated his troops in Yangcun (杨村) and telegraphed Zhili forces in Jiangsu, Hubei, Henan and Zhejiang for reinforcements. However, Anhui clique warlord Zheng Shiqi in Shandong suddenly declared neutrality and took Cangzhou and Machang. In addition, Zheng Shishang's forces completely destroyed sections of Jinpu railway at Hanzhuang.
