The child is not holding the pen in the right position. Can Mo You's Calligraphy Help Children Correct?

My children have been to other institutions before, and some pen-holding postures taught by teachers are wrong. Later, I signed up Mo You Calligraphy for my children. The teacher here teaches the pen-holding posture very formally and professionally, and the teacher has rich teaching experience. They correct their pen holding posture every day. Now children know how to hold the pen correctly and write better and better. . Satisfied, please adopt.
