只有向后才能理解生活；但要生活好，则必须向前看。
You can understand the life only when you look backwords；But if you want to live a good life,you must look forwards.
衡量生命尺度是思想和行为，而不是时间。
It is not the time but the thinking and action that weigh the scales of the life
我告诉你，没有希望的悲伤是没有感情的。
I'll tell you that the sadness without hope lacks emotion
