The correct pen holding posture is that the hand is 2-3 cm away from the pen tip, the index finger and thumb are not crossed, and the first joint of the middle finger is supported. The inclination of a pen is generally 30 degrees.
The correct pen holding posture is best developed when children start reading, which is much simpler than correcting the pen holding posture later. Once the pen holding posture is incorrect, it is impossible for children to maintain the correct sitting posture and the normal distance between eyes and books.
