Tough one.
Basic vowel pronunciation
Basic sounds such as "Th" (Voiced and silent) with the tongue sticking out, and "Sh" as in - It, this is harder than I thought..

I used to teach English years ago while living in Vietnam. I understand where you're coming from. I taught structure formal way of teaching English. It does not work as they are not preparing to take exams or required to write papers. What I found best is to just throw everyday conversational words at them and repeat the same words every lesson basic things like "Hi" to "Hello" and "Where you going?", when you make the sentence like "Where are you going?", its not easy for them as there is no "are" in to translate from the Chinese language, hope this helps. I am in Huizhou as well.
