The way to hold a brush is as follows: press the inside of the first section of the thumb against the side of the penholder, with the thumb in a slightly horizontal position. The first joint of the index finger or the joint with the second joint presses the penholder from outside to inside. The middle finger is next to the index finger and hooks the barrel of the pen. The ring finger is next to the middle finger, and the root of the first nail is close to the penholder to resist the pressure of the index finger and middle finger. Place your little finger against the inner lower side of your ring finger to give it a little more strength. This forms five fingers that evenly surround the three sides of the pen, keeping the pen fixed and the palm of your hand empty.
This is the so-called "five-finger pen holding method". All five fingers of the right hand are used, and the pen is held steadily by the method of "pressing, pressing, hooking, pushing and resisting", so that the fingers can perform their respective duties.
