汗牛充栋

成语故事：唐代有位学者叫陆质，他最爱读孔子的书。他和朋友交谈，满口都是孔子书上的话；他研读孔子的《春秋》几乎花去毕生精力，他写了许多有关研究《春秋》的书。文学家柳宗元很尊敬他，曾写过纪念文章，文章中夸奖陆质书写得又多又好。他说：陆质的书，堆在家里能碰到房梁，出门用牛马搬运，能累得牲口满身是汗。

A scholar in the Tang Dynasty called Lu Zhi, who loves reading Confucius's books. He talked to his friends and filled his mouth with words from Confucius. He spent almost his whole life to study The Spring and Autumn Annals and wrote many related books. Litterateur Liu Zongyuan respected him extremely and wrote a commemorative article which praised the quality of his books is high and the quantity is large. He said “ Lu’s books can touch the beam if pile them up at home. If he go out with these books, he needs to use cattle and horses to carry them, and the animals are tired of sweat.

汗牛充栋后来专用来比喻书多，也可形容著作、音乐等文学产出多。
