Drawing the pen usually refers to the movement of the pen tip into the paper and unfolding the pen, then adjusting the wrist force to change the pen holder from one tilt direction to another direction, and controlling the pen tip to move inwards. This stroke movement is a difficult problem for beginners because their wrist control is not flexible and makes them stiff and dead. The correct method is to practice by starting the pen vertically, entering the paper from the upper left to the lower right and spreading the pen. Be careful not to let the tip of the pen follow the belly of the pen. Stay at the place where the paper enters and spread the pen. Slightly relax the writing force and start to change the wrist. The wrist should have a large range of change. It is better to rub the tip from the current position to the left, and you can clearly see the tilt change of the pen barrel.
