Liu Zhao, a tern, has different requirements for writing brushes. If four regular scripts want to use the same brush, it is only a matter of choice, and the best choice is to choose both wolf and sheep brushes (sheep's hair is softer, wolf's hair is better, and both brushes are both rigid and flexible). The price is about 30 to 40, so it's good to practice a brush. Don't choose too fancy painting style. Famous brands are generally good.
