Here’s the catch: I am Chinese, and I actually have some knowledge of the language. I am capable of understanding some words and phrases, and I have an somewhat-intuitive grasp of it. However, I really would like to master the language. Is there any resource specifically geared towards people like me.
If not, I am also open to suggestions for great resources in general. I would also really like to purchase one textbook to supplement anything I learn online. Does anyone have any suggestions?
