在春秋战国之际，赵简子是一位很有影响的人物。他的活动年代与其卒年的确定很有关系。但关于其卒年的记载，在《史记》诸篇里面相差十几年，令人莫衷一是。本文以《左传》的相关记载为基础进行辨析。联系到先秦时代的丧礼和《吕氏春秋》等文献的记载，可以判断赵简子卒子鲁哀公十八年（公元前 ４７７年）。这对于考定《史记·六国年表》等的相关记载具有一定的价值。 In the Spring and Autumn Period, Zhao Jianzi is a very influential person. The age of his activities has a bearing on the date of his death. However, the records of their death years, in the “Records of the Historian” there is a difference of more than ten years, is incomprehensible. This article is based on “Zuo Zhuan” records as the basis for discrimination. In connection with the pre-Qin funeral and “Lu’s Spring and Autumn Annals” and other documents recorded, you can judge Zhao Jianzi patriarch Lu Ai Gong eighteen years (477 BC). This is of certain value for the examination of records related to the “Records of the Historian and the Six Countries” and other related records.
