厚者不毁人以自益也,仁者不危人以要名。——《战国策•燕策》
A man of kindness and honesty never gains advantages by doing harm to others. A man of benevolence never gets a reputation by endangering others.
士为知己者死。——《战国策•赵策》
A gentleman would even risk his life for those who really understand him.
与人善言,暖如布帛;伤人以言,深于矛戟。——《荀子•荣辱》
Friendly words given to others are as warm as clothes whereas sharp words hurting others bring about much more pain than swords do.
