Help me find an old book?

I can remember reading a children's book when I was in first grade. I'd read it every time we went to the school's library. The book was about five (give or take a few) Chinese (Asian, at least.) brothers, who each had a power. I remember one was capable of holding insane amounts of stuff in his mouth (At one point, he held an entire lake in his mouth, in order to get out all of the fish.), another was able to blow gusts of wind, or something like that, I think...

Anyway, I can't remember the name of it, but would love to know. Does anyone know what I'm talking about?

Agreed, but what can you do in such cases.  It can't stay on the shelves for young readers as they are incapable of such a level of judgement, and at the same time, placing it on the adult shelves would only have any point were the book of any significant interest to, say, literature historians.
