Jullan quoted Chuang Tsu by Zhuangzi
Though you are highly virtuous and trustworthy, if you do not understand the people's spirits, and though you are famous and do not compete, if you do not understand the people's mind, but instead go to a tyrant and lecture him on goodness, ethical behavior, measures, and standards, you are just using the failings of others to demonstrate your own superiority. This is deliberately hurting other people. One who hurts others will in turn be hurt. You will probably end up in trouble.
— Chuang Tsu by Zhuangzi, Gia-Fu Feng, Jane English (Page 60)
