关于杜甫和杨氏夫人的结婚时间,目前学界一般认为是在开元二十九年,杜甫三十岁之时。除此之外,还有四十一岁、三十八岁、二十三岁等不同说法。本文从杜甫的子女出生时间进行逆推后发现,在四十一岁之前,杜甫诗中没有任何关于子女的记载,而在其后生育却相当频繁,故据此推断杜甫应于四十一岁方与杨氏夫人结婚。正是杜甫对“致君尧舜”理想的苦苦坚持,使得他将主要精力放在干谒求仕方面,故而成家较晚。 About Du Fu and Mrs. Young’s wedding time, the academic community is generally considered to be twenty-nine years ago, Du Fu thirty years old. In addition, there are still different versions of the age of 41, 38 and 23. This article deduces from Du Fu’s birth date and finds that before the age of 41, there was no record of children in Du Fu’s poetry and subsequent births were rather frequent. Therefore, it was concluded that Du Fu should be aged 41 Party and Mrs. Young married. It is Du Fu’s insistence on the ideals of “Zhijun Yao and Shun” that he will mainly focus on seeking help from cadres and thus make his family late.
