Is it useful for Mo You calligraphy children to write online?

My daughter's calligraphy foundation is not very good. Mo You has a professional calligraphy teacher to correct her homework, and she corrects her homework every day. And they are all the same teacher. They have learned a lot about children's writing problems and told them more and more carefully. Correct it step by step according to the teacher's explanation and practice hard. Progress is really visible to the naked eye.
