Generally speaking, the longer the brush tip is, the softer its brush will be when the diameter of the brush holder is constant. The shorter the strokes of a brush, the more difficult it is. In fact, to put it another way, the longer the brush tip is, the weaker its waist strength will be, because the longer it is, the smaller its support force will be. Therefore, when we usually write regular script, we should try not to use a long tip when choosing a brush. Generally, it is enough to choose a pen tip with a front end of about 4 cm, in small letters 1 cm. Just like a long-edged brush, it has its special uses, such as writing big grass or big seal script. There are also many calligraphers who are used to using the long-pointed pen, because it is difficult to master and takes a long time to practice. There are still some big differences in the skills of carrying pens, especially the twisting tube method, which is used more in long front pens. Long front pen will have unexpected effects when used well, but long front pen is not suitable for everyone.
Small letters and cursive scripts generally use short-pointed brush, which will be more, mainly because we usually sit down when writing small letters, so it is more suitable for us to put our wrists on the table. Moreover, when writing cursive script, the speed of short front brush is faster, and there are more connections between words. If we use short-ended brush to write, we can improve our ability to control the brush and the probability of success in cursive writing.
