Yes they are excellent! Their teaching approach with their student is very practical, meaning submerge immediately in communicating using mandarin.They correct and gives advice on how to express their thoughts in Chinese. It helps my child(Grade 7) with the Chinese subject and her exam results improved. She can understand and communicate in Mardarin well. Our “Lao shi” really encourage and motivates her student. I appreciate her work and patience. Great help indeed. I will definitely recommend them!
