人们常说,读史可明志。人生有大是大非,在大是大非面前绝不含糊;人生有做人的底线,做人一定要守住底线,在原则问题上绝不让步。有人说,人生是一本书,老年是他的封底,一本书读完了,何必在乎他的封底呢?这话刚听觉得有理,细品起来,就发现不对。中国 People often say that reading history can be clear. There is a big truth in life, and it is in no way ambiguous in the face of being big or small. In life, there is a bottom line in life. Becoming a man must hold the bottom line. Never compromise on the principle. Some people say that life is a book, the old man is his back cover, a book finished, why care about his back cover it? These words just sound reasonable, fine up, they found that wrong. China
