In the spring of 1924, Mao Zedong went to Shanghai to work in the Shanghai Executive Department of the Kuomintang, and made plans in the workers' movement. However, the Communist Party members were excluded by the right-wing forces of the Kuomintang, and frictions and struggles continued. Mao Zedong returned to Hunan to recuperate and continued to seek the revolutionary path. The "April 12" counter-revolutionary coup led to the split between the Kuomintang and the Communist Party. Chiang Kai-shek frantically encircled and suppressed the Soviet area. Mao Zedong insisted on in-depth rural investigations, wrote many immortal articles such as "Xunwu Investigation", conducted great explorations and practices in governing the country in the Soviet area, promoted the economic development of the Soviet area, established a national bank, and effectively cooperated with the anti-encirclement and suppression struggle. However, the left-leaning errors within the party caused major setbacks, many revolutionaries dedicated their lives for the red cause, and the Red Army was forced to march. In January 1935, the Zunyi Conference was successfully held, and the Chinese revolution ushered in a great historical turning point. Since then, the Communist Party of China has followed the correct political direction, stood at the forefront of the historical torrent, and won a great victory.
