Is it useful for children's calligraphy training?

Although calligraphy actually requires learners to practice regularly and quantitatively every day, it is generally impossible for people without relevant knowledge to learn what style of calligraphy they want to learn and how to make a study plan. Calligraphy training can play a guiding role. Of course, it is unrealistic to improve your writing ability in a short time by calligraphy training.
