Compared with a writing brush, holding a pen can be called a single hook, the first joint of the middle finger, and the belly of the index finger and thumb. These three points hold the pen, and the nib is about an inch away from the encirclement. The size of hands is different, and the distance can be adjusted, especially for children with small hands, which can narrow the distance. Looking at the nib perpendicular to the eyes, you can see that the pen is a perfect circle. The first joint of middle finger, index finger and thumb abdomen forms a regular triangle, and the three sides are round lines. The upper part of the pen presses on the last joint of the index finger, not in the tiger's mouth. The little finger of the ring finger naturally leans on the middle finger in turn, without touching the pen, leaving no gap between the fingers, and the whole palm is empty, which is the same as the requirement of holding the pen. When writing, the circle between the little finger and the outside of the palm touches the desktop. When writing hard, the wrist moves hard. Finger and pen are a whole, they move as a whole. Finger and pen are relatively static. This is a basic action of holding a pen, but the size of each person's hand and the uneven proportion of his fingers are still different, which can be adjusted according to his own situation.
