The specific action of using the wrist is that the wrist swings with the pressure of the pen. The range of wrist movement is related to the size of writing.
In addition, the combination of finger force and wrist force can make writing handy. The pen tip has little elasticity, and its pen carrying modes include pause, press, start and close. For example, to write vertically, first press the nib down, and then press the pen down. When writing horizontally, you should also press down to the right, then write down to the right, pause to the right when collecting the pen, and then lift it up. But be careful not to exaggerate the meal.
