First, I was born and lived in the capital of China, I am a native speaker of mandarin and my english is advanced too, so there may not have communicative problems.
Second, according to different students, different situations, I will offer different plans. Such as: if the student has no fundation about mandarin, I would teach form the phonetics and combine graphic technology, also give the easiest and most popular examples, after class, they will know how to pronounce the alphabet and some words.
Third, if a student want to learn well in one langauge, he/she needs to study after class, thus, I will provide some suitable resources to let them study.
