Whether you choose to use copybooks to practice calligraphy or attend calligraphy-related training classes, it actually treats the symptoms rather than the root cause. Although the child may indeed be able to write well in the end, he may not be able to write well in the actual writing process. The good-looking situation, in the final analysis, is that children are very resistant to writing, so I think we should start by cultivating children's interest.
My approach is to enroll my child in the Turtle and Little Rabbit online writing course, and then accompany the child to class every day. The course time is only 5 minutes, and then after class, I will write with the child, and then take the child to class. Upload your works to the Internet and do correction exercises based on the teacher’s comments.
Of course, the most important thing is to encourage and affirm children. Under the influence of parents' example and precepts and deeds, children's interests are actually very easy to cultivate.
