We all come to the world, but why do some of us make great achievements known forever and why are they remembered forever even though they leave the world? And why do some leave the world without anything valuable to his generation and the people? Every one of us will hope to have a significant and valuable life. But what kind of life is both significant and valuable?

　　Answers to the questions are ... "If you cherish your value of your own life, you will create something valuable for the world." Johann Goth said. "The life value should be judged from his contribution rather than his profession." Einstein said. Lei Feng, a communist soldier, said, "one lives to make others a more beautiful life."

　　We'd say it is impossible for one to live alone if he isolates society and people. If he hopes to make a benefit life, he will bring benefit and make contribution to people. we say that a value of life will be only in direct proportion to achievement and contribution he makes to our society. In our real life, we can see many revolutionary martyrs die young for the people. Don't you think they cherish the life? Yes. They do. They are sentimentally attached to life; they are full of hope and desire. But they confront the death bravely and resolutely in order to make many more people live. The life of those who die busy about his lifetime without any achievements can not be compared with their life.
