九牛一毛，汉语成语，字面意思是“九头牛身上的一根毛（a single hair out of nine ox hides）”，比喻渺小、轻微，或很大数量中的极少数，与英文习语“a drop in the ocean（bucket）”意思相近，表示“a very small quantity, especially one that is too small；an insignificant contribution toward solving a large problem”。
例句：
许多公司捐赠食品和药品帮助地震幸存者，但和所需之物相比只是九牛一毛。Many companies donated food and medicine to help the survivors of the earthquake, but it was just a drop in the bucket of what was needed.
同播出的实际开支相比较，他那点酬金不过是九牛一毛。
His fee is a drop in the ocean compared with the real cost of broadcasting.
