How to write chalk calligraphy?

The posture of writing chalk characters is mainly "standing face to face", that is, standing and writing facing an upright board. Because the blackboard is generally fixed, two feet should constantly change their steps and translate during writing. At the same time, with the change of writing process, they should stand on tiptoe, stand upright, or bend their knees, generally writing in the horizontal direction of their eyes, so that students can see it and get good results. The distance between the body and the board should not be too far or too close. It is best to write freely with your arms. If the distance is too close, it will affect the line of sight and cause the line to be skewed; The distance is too far, the arm is weak, and it can't touch the blackboard surface, which causes the body to lean forward and lose its center of gravity, thus affecting the writing effect. The right arm holding the pen should not be straight, but should be curved to ensure the maximum swing space.
