As for the acknowledgement of the modern Chinese semi-colonial, semi-feudal society"s characteristics ,Zhou en-lai stated very deeply and much earlier than Mao ze-dong .the Chinese revolution is that the bourgeois democratic revolution leading by the Chinese communist party and the revolution should be subdivided into "two steps", which Zhou en-lai stated clearly in the first cooperation of the KMT and CP ;while on the Chinese revolution"s motivation problems during Zhou"s early travel of Europe, he divided 5 revolution motivations ,and later clearly pointed out the revolution"s dependent power is workers, peasants, the small capitalist class and the national bourgeoise.

他对于近代中国的半殖民地半封建社会性质的认识，早于毛泽东且论述非常深刻；对于近代中国革命是中国共产党领导的资产阶级民主革命和革命要分"两步走"步骤，周恩来在第一次国共合作时期就已有明确论述；而关于中国革命的动力问题，周恩来早在旅欧时期，就划分了五派革命动力，以后又清楚地指出工人、农民、小资产阶级和民族资产阶级是革命的依靠力量；对于帝国主义列强、新旧军阀、封建余孽和买办官僚，是中国革命的对象问题，周恩来在1924年的《革命救国论》中就已经解决了；中国革命的领导权必须掌握在无产阶级及其政党中国共产党的手里，这一认识周恩来也是很早且非常坚定的。
