Li Shu's horizontal painting began and the horizontal fluctuation ended. A long painting starts with a pen, and the back front rises like a silkworm head; When the shear wave receives the pen, the pen tilts upward and is shaped like a goose's tail.
Why is the swallowtail silkworm head in Lishu the most important stroke in the history of calligraphy?
The source of Yan Zhenqing, a painting of Xuanhe, is "only loyal to heaven and knowledgeable in the world, so the spirit can be seen in the table of calligraphy, which is absolutely inclusive. ..... After popular science, it is to seek the end of its shape, which is called the swallow-tail of silkworm head, and it is only obtained.
There is a kind of strokes in the history of calligraphy in China, which I call "Wang Xizhi in the strokes". In other words, this stroke is extremely important to China's calligraphy. It can be said that it is a watershed between ancient style and modern style, and it is also a watershed of China people's aesthetic change and concept change. This stroke is the "goose-tailed silkworm head" in Lishu (some are also called swallow-tailed silkworm head).
Silkworm head and goose tail are the key strokes in Lishu and China's calligraphy. Before the emergence of the silkworm head and goose tail, China's Chinese writing did not have the concepts of "front" and "twists and turns". For example, the pre-Qin seal script and Li Si's seal script are exposed, which is unimaginable. However, after the twists and turns of silkworms appeared, China people's hearts were moved and their souls were detached. So the official script became rich and colorful, and then other characters were developed from the mother of the official script. It can be said that this kind of silkworm head and goose tail is indispensable.
