Abstract: Local militarization reached its peak in Beiyang period. Because the ruling authorities cannot control the local armed forces, and is unable to provide the excessive expansion of military supplies, warlords gain local living resources frequently by means of apportion, robbery and other crazy ways. For survival or guardian of resources, the local society is differentiated to bandits, spears, and the other armed organizations, which makes more and more people get into the military vortex and unable to extricate themselves.
