Most children who take calligraphy classes want to cultivate their children's attainments in calligraphy. If not, there is no need to take calligraphy classes.
In fact, many children didn't attend calligraphy class, and their handwriting was very good.
For the first-grade children, if parents teach and listen carefully in class, they will certainly be able to write well.
children in grade one just learn to write, so they can't define "poor handwriting". In particular, children should not be allowed to know that they are "poorly written." If so, it is equivalent to putting a label on him, which will have a great impact on his life.
