牛逼的老师！Jiazhen uses just the right level of Chinese in our lessons so that I feel challenged but not overwhelmed. Fun topics discussed and he uses good tools to make use of our time efficiently.

I'm please how much we're covering the HSK3 book. Johnny is also really excellent at correcting my tones, which is my top priority. Excellent teacher.

老师引导得很好，根据我的要求给我设计问题和反馈。在生活化和情景下多练习，口语感觉上来了。👍

好！有理有据

Professional teacher, helping me on mock interviews and giving quite useful suggestions.

The classes are truly fantastic. Jiazhen adapts the lessons so that you are challenged without feeling lost. A wide range of ressources is also used to help you progress. What’s more, Jiazhen puts students at ease, there's no stress, just effective learning.
