Senior high school students still learn pen writing, and learning brush well is of great help to pen writing. Now children are under great pressure to study. Children learn to write with pens. In Xi 'an in the northern suburbs, there are many high school students and college students studying Shu Ren's calligraphy. It is an early calligraphy learning place in our local area. There are children's classes and some are successful. In the fourth grade, my child has been learning writing brush in it. Teacher Cai is very responsible and serious.
