Difference between 谷 and 谷間? I noticed that {} and {} both mean valley in the dictionary. However, when I Google , I get a bunch of pictures of cleavage. Should only be used to describe "valley"? And, can also mean valley but is basically slang for cleavage?

I think is commonly only used to describe "valley".

However has a meaning other than "valley". It is used when you describe low place between high places. For example. (It is cleavage, isn't it?), .
