毛泽东的恩师和岳父杨昌济生前说过,他在湖南省立第一师范学校执教5年,弟子著录以千百计,但是赏识和器重的有3位,即毛泽东、蔡和森和萧子升。毛泽东与蔡和森的关系已人所共知,但由于历史的原因,毛泽东与萧子升的关系却长期以来被罩上了一层迷雾。一些党史论著对此或有意回避,或语焉不详,而某些非法出版物为满足观众的猎奇心理,又利用不实的传闻和史料,大肆渲染,对毛泽东与萧子 Mao Zedong’s mentor and his father-in-law Yang Changji said during his lifetime that he had been teaching for the first time in Hunan Provincial First Normal School for five years.
