How does Teacher Yang Dong study big education?

My daughter is a student of Yang Dong. He is a steady teacher, but he is gentle and considerate to children. My daughter likes him very much. Although he is a male teacher, his mind is very delicate and his English level is quite high. He is patient and responsible for his children. After more than a month's study, his daughter has made great progress in English, knowing more words and speaking accurately. We are quite satisfied!
