Is it important to practice hard pen calligraphy and hold the pen? I can't hold it correctly, but my writing is still good. Do you want to hold the pen first and then practice? I hope a professional answer.
According to Pang Zhonghua, the posture of holding a pen is very important. If the posture is wrong, it is 1, which is easy to cause myopia (because the posture is wrong, you must bow your head, resulting in your eyes being too close to the word). 2. It is easy to cause diseases of cervical vertebrae and spine (because the writing posture is wrong, the thumb is easy to block the line of sight, and the head is unconsciously tilted to one side for a long time, which is not good for cervical vertebrae and spine). The wrong posture is very harmful.
Correct pen holding posture:
Achieve "three ones" (eyes are one foot away from the paper, chest is one punch away from the desktop, and fingers holding the pen are one inch away from the pen tip) and "eight characters" (head straight, body straight, arms open, feet flat).
The first section of thumb index finger holds the pen holder, and the first section of middle finger holds the pen holder, and the pen holder is naturally placed at the spout.
