Where is the calligraphy school in Xuhui, Shanghai?

The situation at that time was the same as that of my children, but it was difficult for children to adapt to a new environment. My youngest son was taken by his grandfather to learn calligraphy. At home, his grandfather taught him calligraphy, and he just scribbled with a brush. However, this children's calligraphy class is very good, called Boju. Teacher Lu is patient and responsible in class. There is a set of courses that can calm my baby down. Now he has passed the third grade exam.
