《战国策·燕三·燕王喜使栗腹以百金为》
不能算尽了忠厚者的本分。 寡人虽然无才，但还不像殷纣王那样昏愤；您虽然很不得意，也没有像商容、箕子那样的忧患。
寡人虽不省乎，未如殷纣之乱也；君虽不得意乎，未如商容、箕子之累也。
I cannot fulfill all the responsibilities of a benevolent person. I may not be talented, but I am not as ignorant and foolish as King Zhou of Yin; you may not be well appreciated, but you do not suffer the same kind of worry and hardships as Shang Rong and Ji Zi.
