Generally speaking, it is of little use unless your child likes it naturally. If your child is naturally quiet and obedient, then you can consider learning brush calligraphy. Let's talk about the reasons why first-grade pupils are not suitable for learning calligraphy: first, generally, first-grade children are active and it is difficult to sit down and write quietly; Second, a first-grade child doesn't even know what words he is facing. It is difficult for him to learn well and he will soon get tired of writing. Third, calligraphy is not effective in a day or two, it is difficult to have a sense of accomplishment, and ordinary children will soon get bored; Fourth, because of their physical development, the first-grade children have poor pen control ability, that is, it is difficult to control the writing brush. Children are advised to grow up before learning.
Calligraphy is no better than children's painting. Calligraphy has no children's calligraphy, only black and white, which will be boring to learn. I suggest you let the children try it first. Don't force them to learn if they don't like it.
