The peasant uprising in the late Tang Dynasty led by Huang Chao led hundreds of thousands of people and moved to Yu Sheng for more than ten years. This is an unprecedented and magnificent peasant revolutionary war in the history of China, which has written a glorious chapter in the history of peasant war in China. It dealt a heavy blow to the rule of the Tang Dynasty and showed the transformation of feudal society by the peasant war. At the same time, the uprising also weakened the separatist forces in the buffer region and broke the original power balance between the central government and the buffer region. This peasant army put forward the battle slogan of "equality" for the first time with the revolutionary thought of "soaring to the sky", established the revolutionary regime and violently attacked the feudal system. It marked the development of the peasant war to a new stage, which had a great influence on the peasant struggle in later generations. The peasant war in the late Tang Dynasty made a series of mistakes in politics, economy and military affairs, which led to a tragic ending. In this peasant uprising, the insurgents adopted the policy of mobile warfare, which showed great superiority. First Cao Pu entered Henan, then invaded Hubei, and then avoided the enemy's main force and strode into the south of the Yangtze River. This is a unique strategy and tactics in the peasant uprising in the late Tang Dynasty. Mobile warfare not only preserves its strength, but also grows stronger with the support of the people of the whole country. In large-scale mobile warfare, Huang Chao's army fled around with Tang Jun, paying attention to one thing and losing the other, which led to the inability of the Tang Dynasty to take care of Luoyang, Huainan and Jiangnan. It is precisely because of the correct use of the early strategy and tactics of the rebel army that it won the victory of capturing Chang 'an. However, mobile operations are prone to the idea of roving bandits and have not established a solid base. Even after the capture of Chang 'an, it was not consolidated. This enabled Tang Jun to reoccupy the areas affected by the insurgents and gradually narrow the encirclement. The Daqi regime also lacked the necessary economic policies, and both production and finance were at a loss. In this way, the balance of power between the enemy and ourselves gradually became unfavorable to the rebels. The landlord in Guanzhong was determined to clear the land, which caused the Daqi regime to fall into a serious food shortage dilemma. In the second year of Zhonghe (882), Daqi (now Dali, Shaanxi Province) defended the same state, causing Zhu Wen to defect and surrender the enemy. At the request of the Tang Dynasty, Li Keyong, a Shatuo, led a powerful force of10.7 million to the south, and the enemy's military strength was greatly enhanced. At this point, Huang Chao found it very unfavorable to be trapped in Guanzhong, so he withdrew eastward in April of three years, attacked and forced Cai Zhou (now Runa, Henan Province), and the Tang Dynasty defeated Qin Zongquan and surrendered to Huang Chao. After Huang Chao conquered Chang 'an, there was no strategy of "chasing the enemy", which gave the remnants of the landlord class headed by Tang Xizong a breathing space, enabled the enemy to rally and fight back against the rebels, resulting in the loss of political power. Dividing the rebels is another way for the enemy to attack. The capitulation activities of Wang Xianzhi and Zhu Wen brought great losses to the revolutionary cause and played a role that foreign enemies could not play. These bloody lessons, but this uprising dealt a powerful blow to the Tang regime, and put forward the requirement of "equal wealth" for the first time, which hit the landlord economy to a certain extent and was of great significance in the history of the ancient peasant war in China.
