The center raises the pen, which is to let the pen tip run in stippling. This method of carrying a pen is the main method of using a pen. In Qing Dynasty, Shigemitsu said in "Green Raft": "The center can be transported, although it is defeated, it is also round; If you can't be a center, you are both good and bad. The root of the pros and cons lies in this. " It is true that the center is the main law in calligraphy, so the center is the most important in calligraphy.
The central stroke, because it is easy to lift the pen up and down, press the pen and use the front, will have different stippling, showing the interest of combining rigidity with softness and vertical and horizontal transshipment. If the carpal tunnel blocks the center of gravity of milli, make it forward. According to the experience of predecessors, if the wrist is vertical, the front part is straight and the front part is regular on all sides, so that you can draw vertically, tighten, stretch, press, lift, and have contact with each other, and the gestures can be aligned with each other, so that the front part can be kept in the center.
