《资治通鉴·汉纪·汉纪四十三》
自从有人类以来，善政少而暴政多，一定要等有了唐尧、虞舜一样的君主，才出来推行自己救国救民的理想，恐怕永远没有这种机会。
自生民以来，善政少而乱俗多，必待尧、舜之君，此为士行其志终无时矣。
Since the existence of mankind, good governance has been rare while tyranny is frequent. You must wait for a king like Emperor Tang and Emperor Shun, then implement your ideal of saving the country and people. I'm afraid you will never have such a chance.
