19 18, Sun Meizhu and others contacted local armed forces and various "poles" to build a village in Baodugu, and his uncle Sun Guizhi was the big village owner and the old village owner respectively. The hungry people in dozens of counties in Jiangsu, Shandong, Henan and Anhui provinces gathered together, and the number of people gathered reached seven or eight thousand. Sun Meizhu was equal to 1920 Tomb-Sweeping Day, and formally established the "Shandong Founding Autonomous Army", with Sun Meizhu as the commander-in-chief of the five-way allied forces.
1922 July 15, Sun Meizhu was killed by an official in an encounter in Xiji. Sun Meiyao was elected commander. At that time, in order to destroy the "Shandong Autonomous Army", the Beiyang government appointed Tian Zhongyu, a Shandong warlord, as the commander, controlled the fifth and sixth Huncheng brigades, the twentieth brigade, the fifth division and other troops in Shandong, and continued to surround the Baogu Mountain area.
1923 during April, there was no water and food on the mountain, and it was in danger of being destroyed at any time. In this case, in order to survive, the "Autonomous Army" decided to lead Sun Meiyao and other key forces to break through the tight encirclement. On the Jin-Pu Railway, people from imperialist countries such as Britain and the United States often plunder "foreigners" by express train, so as to coerce the direct warlords and beat off the encirclement of officers and men. According to the information provided by Shanghai-Nanjing Liaison Station, Sun Meiyao and others learned that the second express train from Pukou to Tianjin had a "West Passenger", so they all took the railway police and the railway police to Zhang Wentong, the public security section chief of Han Zhuang, for their birthday, and demolished the track near Zhuang Ji between Shagou and Lincheng.
