羊毛出在羊身上

羊毛出在羊身上:

Literally means:

the wool comes from the sheep's back

Actually means:

in the end, you have to pay for wha ever you get; there's no free lunch

It figuratively means what is given to somebody is actually from him. It also means the money one spent on something is not actually paid by himself, but is imputed to other relevant parties.

比喻给某人的钱物，原本就是从这个人身上得来的。也指为某件事情所花的钱实际上不由自己承担，而是转嫁给有关方面。
