Pen paste: how to paste the ancient classic brush paste with a pen?

The key is that an absent-minded pen is not like a writing brush, which can obviously change its feet, but this is also the characteristic of a pen. The most important thing of the ancient post is that the foot retaining part of the shelf structure should not be too demanding (of course, it is not completely abandoned). Pay attention to the characteristics of the pen. There is no obvious change in thickness and strokes. Being good at using is the characteristic of the pen (you can find some ancient posts printed on smaller paper to meet the size of the pen), and you will certainly make progress slowly.
