这是一个结构不对称的故事。因为我的祖父祖母的晚年缺少对称!很多人把退休后的时光称为晚年。如果此定义成立,那么我祖母方于教授的晚年从1963年就正式开始了,2002年谢幕,历时近40年;而祖父李丹的晚年生活始于1974年,1977年中断,历时3年! This is a structural asymmetry story. Because of the lack of symmetry in my later grandmother’s old age, many people refer to their retirement as old age. If this definition is true, then my grandmother formally began in 1963 in his later years of teaching, and the curtain call in 2002 lasted nearly 40 years. The grandfather Li Dan’s later life began in 1974 and was interrupted in 1977, which lasted for three years!
