《资治通鉴·汉纪·汉纪四十六》
民间有谚语说： 偷盗不经过五女之门。 因为女儿多会使一家贫穷。如今后宫有这么多美女，难道不使国家贫穷？ 
鄙谚言 盗不过五女门 ，以女贫家也；今后宫之女，岂不贫国乎！ 
There is a proverb that says: "Thieves do not pass through the gates of five women." That is because having many daughters can make a household poor. Now, with so many beautiful women in the imperial harem, will that not make the country poor?
