Chinese is super hard to learn, as I included some reasons in my other writing. The writing system takes forever to learn, think about writing thousands of symbols in a newspaper each day in China. That would be hard work, don't you agree?
Grammar in tone changes is not really native here in America. I mean look how many speakers are in China, Millions, maybe even reaching in the billions somewhere.
My decision to learn to learn Chinese was hard, but fun at the same time.
