Maybe you've heard people say that you are stupid before: just learning calligraphy, you must use wool, which is soft and can be used to practice brushwork. This view seems reasonable, but it is groundless. According to textual research, writing with wool became popular only after the Southern Song Dynasty. But it was widely used after the early Qing Dynasty. "Because the Qing Dynasty paid attention to roundness and delicacy and was not allowed to show off talents, only soft wool could meet the requirements and was widely used at that time."
Before that, everyone had been using bristles. It is said that Wang Xizhi probably wrote the Preface to the Lanting Pavilion with a moustache (although the hair of this moustache remains to be verified, at least it shows that he used a hard brush). In addition, "a soft brush may not be able to practice writing ability, and writing ability depends on active exertion, while too soft wool is easy to develop the bad habit of dragging pens, which is not conducive to the cultivation of active exertion habits."
Second, don't use a long brush.
If the long front brush is made of animal hair, the cost is extremely high. The best long-peak wool brush is about 6 cm long. The output of this long-peak wool brush is very low, and sometimes it takes months or even more than a year to save enough wool for this brush. The same is true of wolf hair and purple hair. The longer it is, the more expensive it is.
Third, try not to use nylon brushes.
Fourthly, it is suggested that beginners use double brushes or back brushes, and double brushes are the first choice. In addition, the post number mainly includes wolf number, font size and auspicious number.
