凡与人交，不可求一时亲密，人之易见喜者，必易见怒：惟遵礼致敬，不见好，亦不招尤，所谓淡而可久是也。 If you make friends with others, you can't ask for a moment of intimacy. If people are easy to see happiness, they will be easy to see anger: but if you follow the ceremony and salute, you won't see good, and you won't invite special attention. The so-called "light but long" is also true.
