Gang and Rou
Two opposing properties or qualities that objects and human beings possess. The term has three different meanings. First, when describing natural or manmade objects, gang (刚) means hard androu (柔) means soft. Second, when describing human qualities, gang means strong and determined, while rou means gentle and modest. Third, when describing a style of governance or law enforcement, gang means strict and rou means lenient. Gang and rou are one of the manifestations of yin and yang. Their mutual opposition and accommodation are the basic causes of change, and they must achieve a certain balance within any object or action. Too much of either is inappropriate and dangerous.
