Today, 91 years ago, on May 6, 1934, the Central Committee of the Communist Party of China (CPC) criticized the rebel expansion. The Central Committee of the Communist Party of China sent a letter to the Central Branch of Xi'an. The letter severely criticized the rebel expansion mistake of the Central Branch of Xi'an and the "disbanding of all Party organizations" and the "cancellation of all mass organizations" mistake, demanding "resolutely correct the wrong rebel line from top to bottom and establish party and group organizations at all levels" and opposing the struggle to replace the two lines of rebel within the Party, instructing that "the rebel is to initiate a broad mass, through the mass front, and be closely linked to the daily struggle of the masses."
