自从 １８９７年罗正钧编著《左文襄公年谱》以来，有关左宗棠的专著无一例外地都将左宗棠主讲渌江书院的时间系于 １８３７年，历时一学年。时逾百年，无有置疑者。其实这是一种人云亦云的讹传。依据对当时有关人物的行踪、关系以及左宗棠本人在内的证述，左宗棠受聘担任渌江书院山长，并与陶澍首次会见，是在１８３６年；１８３７年又接受续聘，共主讲渌江书院两个学年。 Since Lok Ching-kwan’s “Yearbook of Zuo Wenxiang” was compiled by Luo Zhengjun in 1897, all of his monographs written by Zuo Zongtang, without exception, date Zuo Zongtang’s speech on the Hanjiang Academy in 1837, which lasted one academic year. When more than a century, no doubt. In fact, this is a parrot rumor. According to the account of the whereabouts of the persons concerned, their relations and the account of Zuo Zongtang himself, Zuo Zongtang was hired as the head of the Qijiang College and met for the first time with Tao Shu in 1836 and re-employed in 1837 Lecture Jiang College two school years.
