Bai Fei is a special brushwork of calligraphy. According to legend, it was created by calligrapher Cai Yong, and was inspired by a craftsman who repaired the Hongmu Gate, and dipped a broom in lime water. Its stroke part is parallel to the dead silk, and the stroke at the turning point is prominent. In the Northern Song Dynasty, Huang Yue said, "Take the handwriting of its hair as white, and fly if you fly." Now the dry strokes of calligraphy and painting are also called flying white. In writing, the strength is generated, so that the dry pen is "flying white", which is in contrast with thick ink and rising ink, so as to strengthen the sense of rhythm and rhythm of the work. At the same time, "flying white" can be used to make the characters present vigorous and simple artistic effects, make the works more interesting and enrich the visual effect of the picture. Of course, the skill of calligraphy can also be fully reflected in Flying White.
The use of flying white in calligraphy embodies a kind of artistic beauty.
