因此，要学会微笑；微笑是我们幸福的源泉。

原文英文

Everyone may encounter happiness or meet pain unexpectedly. We can tuck away the passing years, whether through joy or sorrow, and quietly store the vicissitudes of life, whether deep or shallow. Sometimes, the obstacles in life are not necessarily bad things, as they allow us to appreciate the scenery along the way. Through many people and events, the heart becomes stronger; by crossing many hurdles, the mind becomes more open. Learn to walk lightly, learn to let go of burdens, understand deeply, and fly quietly.

Some elderly people, despite their wrinkles, bring warmth and approachability through their smiles. Some children, despite their young age, bring infinite warmth and happiness through their smiles. Therefore, learn to smile; it is the source of our happiness. Smiling costs very little but yields great results. Let us smile more.

交有道之人，绝无义之友；饮清静之茶，戒花色之酒；开方便之门，闭是非之口。多门之室生风，多言之人生祸。世事忙忙如水流，休将名利挂心头；粗茶淡饭随缘过，富贵荣华莫强求。“我欲”是贫穷的标志。事能常足心常惬，人到无求品自高。人生至恶是善谈人过，人生至愚恶闻己过. Even if you have been kind to others, do not expect praise or rewards; even if fate is unkind, do not extinguish the lamp of hope; even if you are wronged, do not be petty or dwell on it; even if you achieve some success, do not become complacent or self-indulgent; even if you face injustice, do not let it dampen your spirit.
