Confucius said: " Yu the Great's conduct, I could not point out any flaws. He consumes meager amount of food, while offering boastful riches to the Gods and ancestors; He always don the crudest attire, but wears lavish garments when worshipping; He resides in a small house, yet forges water ways and ditches with all his might. Figures like Yu the Great, I honestly cannot point out any reprehensible flaws."
