2. Grasp the weight of the pen. It is very important to control the pen and grasp the priorities;
3. The choice of pen should not be too fine;
I recommend two: 1) calligraphy pens;
2) Self-made-with a big pen tip, it bends in the opposite direction and has a certain radian. Such a pen tip needs hardness and self-adjustment; Nothing more than for the convenience of control, only rough and fine can show the change of brushwork.
