Chinese traditional paintings have usually some Chinese 
letters written on them (as I said in the previous post) which brings  some effect and usually done intentionally. Chinese letters are more figurative than alphabet.
simple ones
川    -    River (looks like a river though very simplified)
山    -    Mountain
medium-ly complicated
魚    -    Fish (looks like fish if you are imaginative)
鳥    -    Bird
One of the most complicated ones
龜   -     Turtle (looks like a turtle, isn't it ?)
But even alphabetical letters have some effect too. See below.

The letters are hand-written copies from the tree flower books I have.
