The characteristics of extended information cursive script;
In the Tang Dynasty, cursive script, represented by Zhang Xu and Huai Su, became an artistic creation completely divorced from practicality. The cursive script, also known as the big grass, is bold and unrestrained, with a continuous momentum, such as Zhang Xu's Thousand Stones, the Four Methods of Ancient Poetry in the Tang Dynasty, and the Autobiographical Post by the monk Huai Su. Zhang Xu was called "the sage of grass" in history, but Sun's "Pu Shu" is another way of saying it, and there is no connection.
"Big grass" and "small grass" are symmetrical. Big grass is pure grass-based and difficult to identify. Zhang Xu and Huai Su are good at it, and their words are written in one stroke, sometimes out of line, but the context is constant. In Qing Dynasty, Feng Ban gave a lecture on cursive script in "Blunt Printing Book": learn from it, learn from it, learn from it, and learn from Zhang Xu as weeds, so it is better to learn from Huai Su. Huai Su's cursive script is easy to recognize, the handwriting is fine, and the relationship between words is clear and easy to put pen to paper.
