I want to buy a writing brush to practice calligraphy. I wonder what I should pay attention to when buying a writing brush. Please advise, thank you!

1. When choosing a brush, wash it according to the purpose. When writing running script, couplets and leveling, you can choose wool pen and wool quilt, which are soft and tender and have a wide range of uses. Zihao and Langhao pens are hard and elastic, and the regular script is short and the painting is long. On the other hand, the double-stranded brush is both soft and hard, which can be used for writing and painting.

2. The three numbers of the brush are divided according to the length and thickness of the brush head, and users should choose the model according to the size of calligraphy and painting. The longest "crane's foot" is 12 cm long, and the shortest "person" is only 1.5 cm. The hawthorn pen with a "fat" nib is 8 cm long in diameter, while the pen for drawing flowers is the thinnest, and the nib is as thin as cotton thread. Choosing a brush is picking the tip of your hair.

3. The nib should be sharp, neat, round and key, that is, the leading edge of the nib should be sharp as a cone and round, the nib should be neatly trimmed, and the nib should be full and elastic.

4. The pen holder is generally made of Phyllostachys pubescens, Phyllostachys pubescens, Phyllostachys pubescens and Zizhu. When choosing a pen container, it depends on whether the pen container is round and smooth, not flat, not cracked, not bent or inclined, and the length is moderate. If there is seal cutting on the pen, it depends on whether it is clear; If there is a mosaic, it depends on whether it is elegant and simple.

Finally, it depends on whether the nib and the pen stick together, and whether the nib is moldy or moth-eaten. First, gently shake the pen with your hand to make it not loose, and then gently flick the pen to see if there is hair loss, either moth-eaten or moldy. Check whether the brush tip is moldy. You can smell it.
