Child 10 years old, and now his handwriting is very bad. Is it useful to sign up for Mo You calligraphy?

My children started using excellent ink calligraphy at the age of 10. He wrote "Spider Climbing" before, and later he was awarded an excellent ink calligraphy, which is really useful. The fonts taught in their home courses are the same as those in primary school Chinese books, which can help children keep an advantage in daily life and exams. Moreover, according to the classification of basic strokes and radicals, children are guided to learn systematically from simple to difficult, and the course is relaxed and enjoyable. Children learn easily and their self-confidence naturally increases a lot. My children have been learning Mo You's calligraphy for less than two months, and their calligraphy is much neater. Now they have prepared for the calligraphy exam. Seeing their progress, I am really happy as a parent.
