蔡和森与毛泽东是我党两位伟大的革命领袖。他们从青年时代开始建交,始终志同道合、心心相印、肝胆相照,在思想上相互产生着很深的影响。学界名流杨昌济教授对毛泽东、蔡和森二人评价极高,他曾对章士钊说:“二子海内人才,前途远大。君不言救国则已,救国必先重二子。”李立三在1935年撰写的《纪念蔡和森》的文章中也曾指出,“远在五四运动以前,在湖南的一般先进青年中,就盛称毛蔡之名,而奉之为表率。” Cai Hesen and Mao Zedong are two great revolutionary leaders of our party. Since the establishment of diplomatic relations between them, they have always had the same status as one another and have always had the same influence. Prof. Yang Changji, a celebrity in the academic field, highly appraised Mao Zedong and Cai Hesen both. He once said to Zhang Shizhao: “There is a bright future for the two sons,” said Li Lisan in 1935 In the article entitled “Commemorating Tsai Hsueshen,” it has also been pointed out in the essay that “far before the May Fourth Movement, among the most advanced youth in Hunan, Mao Tsai was proclaimed the epitome of Mao Tsai.”
