2. The period of the new warlords of the Kuomintang: After the fall of Beiyang government, the new wars among the new warlords of the Kuomintang were famous, including Jiangfeng War, Gui Jiang War and Zhongyuan War.

In addition, there are countless wars between local warlords, including hundreds of warlord wars in Sichuan Province alone.

The warlord melee in the Republic of China brought a heavy disaster to China.

1, economic and social development has been seriously hindered. Warlords all over the country are divided, and the central government has never formed strong control over the localities, and basically no unified market has been formed throughout the country. The railway system is complex, there is no national unified railway network, and the roads are mixed. Power supply and voltage vary from place to place, which seriously hinders the development of productive forces.

Britain actively pursued the policy of invading Tibet, wooing and threatening the local government in Tibet and alienating the central government; The Japanese emperor launched a full-scale war of aggression against China.
