What size brush do you usually use to write couplets?

The brush used to write couplets is generally not too big, about one-third of the size is enough.

Tips for choosing a brush:

The above three kinds of pens with different properties, namely, hard pen, soft pen and double-headed brush, have different uses. Before the Song Dynasty, most calligraphers used hard pen to write. In the Ming and Qing dynasties, calligraphers wrote more and more words, and the pen changed from hard pen to sheep hair. Because wool is long, it is suitable for making big characters. Generally speaking, writing running script and cursive script with hard pen is refreshing and easy to write, easy to rise and fall: writing regular script, official script and seal script with soft pen is easy to moisten and enrich.

Of course, this is not absolute. You can write regular script, seal script and official script with hard pen, or you can write cursive script with sheep hair. Mr. Lin Sanzhi, a contemporary grass sage, writes cursive script with a long and soft brush, which is not only vigorous and upright, but also smart and meaningful. Because the pen tip is long and contains a lot of ink, a few words can be written when dipped in ink, which is easy to show the continuous momentum between words and the change of ink color.

Because Changfeng Yang Hao's pen is soft and long, Cai Yong in the Eastern Han Dynasty called it "strange soft pen", so it is easy to produce endless changes and unexpected artistic effects. However, the sheeppaw pen is soft, especially the long-side sheeppaw pen. When the pen is pressed, it will lie flat and spread out, which is difficult to grasp.

At this time, it is entirely up to the writer to adjust the nib with the skill of lifting the pen, and the bristle brush is better. Because of its high elastic strength, when the pen is pressed and lifted again, the pen tip can be restored to the original condensed state, so it can be lifted freely and is quite handy. However, due to the hardness and flexibility of the brush, the strokes will appear too sharp and angular, which is the disadvantage of the bristle brush.

In short, it is not easy to write vigorous and straight words with a sheep's brush and peaceful and flexible words with a hard pen.

For beginners, if you use a hard brush from the beginning, it will be easier to pick up the pen without much skill, because the pen will help you a lot, but over time, you can only use a hard brush. Once you pick up the sheep's hair, you will feel unable to move.

On the contrary, if you practice calligraphy with sheep hair when you are a beginner, although it is difficult at first, you must use the method of lifting the front to write qualified strokes, but you also learn the method of using soft pens. With the increase of practice time, you will gradually become handy and use it freely. At this time, if you pick up a hard brush to write, you will feel relaxed.

The ancients also had a lot of experience in the use of pens. I don't think it is easy to buy a good and expensive pen when I am a beginner, but I advocate using a bad pen, because if you can write good words with a bad pen, you will be more comfortable and write better with a good pen.

On the contrary, if you start with a good pen, you will only use a good pen all your life. Once you encounter a poor pen, you will not be able to write well. Of course, you can't practice calligraphy with a rotten pen, which will make it more difficult for beginners. Ou Yangxun, a great calligrapher in the early Tang Dynasty, recorded that "if you don't choose paper or pen, you will achieve your goal", which was praised by Yu Shinan of the same age.
