The site of the August 7th Conference witnessed the first great turning point in the history of China. 1927 spring and summer, the surging anti-imperialist and anti-feudal mass movements swept across the country. Imperialism, feudalism and all domestic reactionary forces, which suffered heavy losses, joined forces to suppress the revolutionary movement. Chiang Kai-shek and Wang Jingwei Group successively launched counter-revolutionary coups in Shanghai and Wuhan, massacring the people and the revolutionary masses, and the Kuomintang-Communist cooperation United front broke down and the first Great Revolution failed. At this critical moment, the Central Committee of the Communist Party of China held an emergency secret meeting at No.41Sanjiao Street in Hankou on August 7th to study and solve the future and destiny of the China revolution. This meeting corrected and ended the right opportunism mistakes within the Party, summed up the experience and lessons of the failure of the first Great Revolution, determined the general policy of agrarian revolution and armed resistance against the Kuomintang reactionaries, elected a new leading body of the CPC Central Committee, pointed out a new way out for China, who was confused in thought and disorganized, and made great contributions to saving the Party and the revolution. This is a historic change from the failure of the Great Revolution to the rise of the Agrarian Revolutionary War.
