郑老师絮语:人都有喜怒哀乐,常常溢于言表;人都有笑容,常常喜形于色。作者认为,这些都是浅表性的,而具有深层内涵的笑容,却是在经历痛苦磨砺之后才展现出来的,或者说通过痛苦磨砺之后大彻大悟,那时,所展现出来的笑容才是真实的笑容、美丽的笑容。作者的见解含有一定的人生哲理, Zheng teacher whispered: people have joys and sorrows, often overflowing with words; people have smiles, and are often pleased. The author believes that these are superficial, but smiles with deep connotations are only revealed after suffering painstakingly, or after a painful tempering, the smiles displayed are true at that time. Smile, beautiful smile. The author’s opinion contains a certain philosophy of life.
