In 1927, the counter-revolutionary coups of April 12 and July 15 occurred one after another, and in order to save the revolution, the Central Committee of the Communist Party of China held the "87 Conference" and decided to appoint Mao Zedong to lead the armed uprising in the autumn harvest in the Hunan-Hubei-Jiangxi border area. On September 9, Mao Zedong announced an uprising, and personally led the Third Regiment of the First Division of the Workers' and Peasants' Revolutionary Army to win the first battle, victoriously occupying Baisha Town, Dongmen City and other places. However, soon the attacks of all regiments suffered serious setbacks, and Mao Zedong immediately changed the plan to attack Changsha, and after discussion, the troops decided to transfer troops to southern Hunan. Mao Zedong quickly led the army to evacuate to Sanwan, and the troops carried out the famous "Sanwan Reorganization", which fundamentally established the party's absolute leadership over the army. On April 28, 1928, the troops of the Autumn Harvest Uprising led by Mao Zedong and the Southern Hunan Uprising led by Zhu De triumphantly joined forces in Jinggangshan, forming the largest and strongest revolutionary armed forces under the leadership of the Party, marking the true birth of the predecessor of the Chinese People's Liberation Army, a Chinese Workers' and Peasants' Red Army loyal to the Party and serving the people wholeheartedly!
