小时候，幸福是一件东西，拥有就幸福； 长大后，幸福是一个目标，达到就幸福； 成熟后发现，幸福原来是一种心态，领悟就幸福。
When we were children, happiness was a thing, and we were happy when we had it; when we grow up, happiness is a goal, and we will be happy when we reach it; after maturity, I found that happiness is actually a state of mind, and understanding is happiness.
