Confucius said: "If a worker wants to do his job well, he must first sharpen his tools."
   The brush is an important part of Chinese calligraphy and painting. Without the brush, there would be no linear characteristics of Chinese calligraphy and painting. The inkstone does not need to be washed frequently, and the ink left overnight is called staying ink. You must not be lazy when it comes to writing brushes, because the brush hair will fade, the pen tip will break, and the pen barrel will crack or even bend. Moreover, nowadays, good writing brushes must be expensive. Writing satisfactory works naturally depends on good writing brushes. Therefore, I believe that among the four treasures of the study, the writing brush is the one that everyone should cherish the most.

  Washing brushes is inseparable from water, and of course the water must be clean water. Don't be stingy with water, because it takes a lot of water to clean a brush. Write it out for your reference:

  1. Use up all the ink in the pen bristles
  This is to make pen washing simpler. The method is that after writing, you can just scribble on the paper without dipping it in ink until all the ink in the pen is used up. It is said that the master Huang Binhong paints with a blend of ink and ink. After painting, you don't need to wash the brush, just wipe it dry on your clothes, because the ink in the brush has been used up, and in the process of dipping it in water, the brush hair has been cleaned. I think people who are familiar with the pen and the theory of ink can do it.

  2. Soak the pen first and then wash it
  It is best to wash the brush in a fixed container, such as a basin, sink, etc. Soak the brush in a certain amount of water, not too much water, just enough to cover the brush. Soak for about 20 seconds, which can disperse the ink in the pen belly and make it easier to wash the pen. Just don't soak the brush in water. In a few days, the brush barrel will crack, damaging the expensive pen. There is no room for laziness when it comes to washing pens.

  3. Do not damage the pen by washing it
  When washing the pen, always keep the pen tip downward. You can gently fiddle with the pen bristles with your fingers, but do not pull out the pen bristles with force. You can stir the pen tip in the water, but not for too long, as this will damage the pen base. The brush should be washed until the brush is lifted out of the water, and the water that oozes out when squeezing the bristles with your fingers does not contain too much ink, so that the brush is basically clean. Finally, squeeze out the remaining water in the pen with your fingers or absorbent paper to end the pen washing process.

  4. How to wash multiple brushes
  If you wash multiple brushes at the same time, in order to better protect the brushes, it is best to wash the brushes separately, because the materials of the brushes are different, including jianhao, Yanghao, Langhao, Zihao, etc. The ink content of Yanghao and Langhao , must be quite different. By washing them separately, you can basically clean every pen.

  5. Maintenance of brushes after washing
  After washing the brush, it involves daily maintenance of the brush. One important thing to note is that the brush cannot be placed with its head upward. Because then the remaining moisture in the brush will seep into the pen barrel, causing the pen barrel to crack and eventually the pen tip to fall off. In this situation, colleagues in the north need to pay special attention to this situation. Try to hang the tip of the brush downward or place it flat in the pen curtain, so that the brush will dry naturally and the bristles will be dispersed, making it easier to use next time.
  Another point to mention is that not only does the ink stink, but it can also damage the pen. Because the molecular structure in the ink changes, the damage to the pen hairs will be obvious, so it is best not to write with permanent ink. The ancients said: "Exquisite writing and ink bring happiness to life." If we treat our brushes well and use them for a long time, they will become natural and good works will emerge.
