Mo You Calligraphy is a very good calligraphy training institution in Qingdao. My children's primary school has been cooperating with them. Before that, they also reported offline. The children responded that what the teacher said was very easy to understand, unlike the calligraphy class he reported before, the theoretical knowledge teacher said was too obscure, which invisibly increased the children's understanding difficulty, and their online courses were also good. They all condense the good offline content into a 3-4 minute online video for children to watch easily.
