Answer

1. 阴阳 ：refer to Ying and Yang in English
 2. 中庸： refer to the action and attitude of moderation 
 3.  顺势而为：take an action according to the tendency
 4. 武侠：WuXia, related to Chinese Kongfu

Answer

I'm not a really good translator, but I will try.

1. "阴阳" - Ying and Yang (if you say this most foreigners know this; if not then use black and white, for one to exist there must be an opposite.)
2. "中庸" - Doctrine of the Mean (one of the Four Books, part of the Confucian canonical scriptures; from wikipedia)
3. "顺势而为" - ?? (I'm not sure but maybe it's Seize the day)
4. "武侠" - WuXia; This is the code of chinese martial arts, an unwritten rule, an honor system that chinese martial artists follow.  For example The Japanese Samurai, I'm sure most westerners have heard of bushido, that is their code called.
