Jun(君) and Chen(臣) often appear in pairs in ancient literature. Jun is combined with 尹and 口. The structure of 臣 resembles a capture staring in anger. The 尹 in 君shows a person seizing power while 口 means both giving commands and taking in criticism. Therefore, 君 is restricted by ceremonial behavior standards when endowed with great power. 臣, on the other hand, even evolves from war capture to court slaves, then to administrators of state affairs, still remain to be subjects to monarch. In Confucius philosophy, 礼 does not refers to blind loyalty, but the brave spirit of making right suggestions without fears of offending royalty.
