I don't think Chinese language is the most difficult.. For me, as foreigner the most difficult thing about Chinese is pronunciation. Characters? Those are time consuming only, but not difficult. I'm not learning Chinese right now, but it's one of languages I like a lot. hmm.. For example Russian language I've been speaking from the childhood along with my native language seems much more difficult than Chinese to me in every respect but pronunciation and writing. It doesn't mean Chinese is easy to learn... not at all. In fact there's no easy language to learn. And one can never learn wholly even .... NATIVE language. Because language is alive, it's just like a living thing. It doesn't stand still.

Chinese isn't even close to being the most difficult language in the world. Do a Google on this and you will get some nice surprises. The prize would appear to go to Polish.

i want to learn chinese and korean but both are equally difficult for me. i didn't find anyone here who can guide me and teach me chinese but i will someday.

Every language is easy to natives and difficult to non-natives.

I think so.
