1. The sitting posture is incorrect.
2. Holding the pen irregularly.
Correct sitting posture:
Write with three ones: one punch, one foot and one inch. One punch is one punch to the chest from the table, one foot (one elbow) from the eyes to the table, one inch (two finger widths) from the hand to the tip of the pen.
The correct posture for holding a pen is: holding the pen with the index finger and thumb; holding the pen with the middle finger, lying on the tiger's mouth.
There is a formula for holding a pen as follows: - press twice and set off three times, the finger is solid, the palm is empty, the wrist is flexible, the angle is suitable and the direction is correct, and the weight of the strokes is carefully considered. "One touch" refers to using the nail of the middle finger to hold the pen from the bottom of the pen barrel from bottom to top, leaving a distance of one inch from the pen barrel, usually by unscrewing the tapered root of the pen knife. "Second pressure" means to use your thumb to pinch the pen from the inside and your index finger from the outside and then press it down gently. The belly of the thumb and index finger should be pressed hard. In this way, when pinching, the belly of the finger will be large, the flesh is soft and thick, and it doesn't take a lot of effort. It takes a lot of force to hold the pen tightly. "Three supports" means that the ring finger and little finger are slightly bent back and forth, and the two fingers form a flat surface and are attached to the table. In addition, the palm side should be firmly attached to the table, so as to support the middle finger and the entire pen, forming a stable and flexible pen grip. Posture
