There is a transparent or blue part near the tip of the brush tip, which is the brush tip. In addition, the sharp edge of the characters is also called "brush edge".
When using the pen, if the tip of the pen is kept within the dots of the characters, it is called "center"; if it is hidden in the middle of the dots without coming out of the corner, it is called "hiding the tip"; The dotted side of the character is called "biaofeng". It is generally believed that "bias" is a disease of calligraphy.
The elasticity of the brush itself is determined by the "edge". The longer the edge, the stronger the elasticity; the longer the edge, the fuller the ink content; when written, the stipples will be thick and thin, flowing and mellow. Of course, the "edge" plays the role of straightening the brush as soon as it is lifted and falling down as soon as it is pressed, as well as the pauses and setbacks of stippling, the criss-crossing and connecting of characters, etc.
Extended information:
Bi Hao and Bifeng are two concepts as a whole. A high-quality brush must have two elements: brush hair and brush edge. Generally, high-quality pens have both high-quality nibs and high-quality edges. For example, low-quality hair, inferior hair, and waste hair can also be used to make brushes. They look like a brush from the outside, but they actually have no hair. Front.
The brush tip plays a very important role in the brush head. For example, in the process of writing, you can use the center, side, or exposed front to turn freely, press the pen to lift the pen without inverting the front, and not scattering the front, etc., which can all be accomplished through the pen edge. Twist the front tip of the pen tip with your hands, flatten it and look at it under sunlight or light. There is a relatively transparent and crystal-clear part, which is the tip of the pen, also called the tip, or simply the tip.
