Please help name a movie

On another forum a guy pm's me and says this,"back in the 90's i've seen some kung-fu movies with kids (i don't remember how many-maybe 5).one was fat,they have a granmother.I remember a scene at the river,they were washing clothes.
maybe you can help me with some information of any kind."

I know this kind of thing is a specialty here.It's like "name that tune", except with vague descriptions of movies.I told him I would ask you guys because if anyone knows, this group would.Thanks for any help.

Maybe that Shaolin kids movie with Jet Li... or some of those Taiwanese kung fu kids flicks!

No.He said that wasn't it.Here are more details from him."i know that movie and no that's not the one.
I remember more details:the movies should be made 85-90.
one of the movies starts with a scene at a river,washing clothes,the fat kid has a basket to pick the dry clothes,he also has a patch on his pants(and sometimes farts while fighting).
they have a granny not a grandfather.I think she plays the death in a movie and flies.
these are some scenes that are comming to my mind.
thank tou for your time."
