“九一八”事变后，日本将中国东北地区变成了它的独占殖民地。建立抗日民族统一战线，共同抗日，是东北人民的主要任务。但由于以王明为代表的“左”倾冒险主义、关门主义错误在中共中央占统治地位，错误地在业已成为日本独占殖民地的东北地区推行与南方一样的“土地革命”政策。其结果不但没有达到预期的设想，反而给东北地区的抗日斗争带来了严重的影响和危害。 After the “September 18” incident, Japan turned northeast China into its monopoly. The establishment of an anti-Japanese national united front and the joint resistance against Japan are the major tasks of the people in northeast China. However, due to the “leftist” adventurism represented by Wang Ming, the mistake of closing a door dominates the Central Committee of the Communist Party of China and erroneously applies the “agrarian reform” policy in the northeast region that has become the monopoly of Japan as the South. The result not only failed to reach the expected assumptions, but brought serious repercussions and harms on the anti-Japanese war in the northeast.
