Soft brush may not be able to practice brushwork, but it depends on active power, while too soft sheep hair is easy to develop the bad habit of dragging pens, which is not conducive to the cultivation of active power habit.
Second, don't use a long brush.
If the dragon and phoenix brush is made of animal hair, the cost is extremely high. 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.
When Qi Ming first learned calligraphy, he especially liked to use a brush with more nylon content, because he thought it was effective, flexible and easy to "control". Later, with my own level and understanding, I gradually began to dislike this kind of writing brush, and turned to double both writing brush, mainly a wool, or sheep and wolves, and felt that it was more handy to write.
Fourthly, it is suggested that beginners use double brushes or back brushes, and double brushes are the first brushes. In addition, there are three kinds of hard hair: wolf hair, purple hair and chicken feathers. About wolf hair.
