People live for a lifetime, grass and trees in autumn, and a good mood is the wealth of life. In this life, in the final analysis, what lives is the mood. In just a few decades, happiness is also a day, unhappiness is also a day, time will not go backwards, life can not come from, there is no good mood, it is uncomfortable is yourself, why bother yourself. Life is not easy, life is hard, but we must laugh, keep a good mood, laugh at life, so as not to waste this trip to the world.
