君子敬以直内，义以方外，敬义立而德不孤。《周易 卷一》

A man of noble character upholds respectfulness within, and demonstrates righteousness in all his actions for the public. As such, his respectfulness and righteousness are established and will win friends all over around him. -- 《Zhou Yi, Vol. 1》

Confucius said， " If those in power are able to conduct their own actions justly and properly, what difficulty will they have in running the government? If they could not rectify themselves, how could they redress others' behaviors?" --《The Analects Vol. 9》
