What are the characteristics of Huai Su's Wild Grass compared with others?

Huai Su's cursive script features: Huai Su is good at using the pure momentum of the central pen as a big grass, such as a shower whirlwind, full of momentum, suddenly calling three or five sounds, full of words. Although the speed is fast, Huai Su can cross the grass with few mistakes. Compared with the confusion and omissions of many calligraphers, it is much better. Wild grass knows Huai Su. Although it is the first, it is ever-changing and will never leave the statutes of Wei and Jin Dynasties. This is really due to his extreme penance. Their styles are not all the same. They can be divided into three types: 1. Those who didn't completely get rid of their predecessors' styles, such as Notre Dame, Eating Fish, Hard Training, Zang Zhen, and Zhu Tie, kept a lot of golden laws, and Notre Dame Iron has Yan Zhenqing style. 2. He has his own style skills, such as Pure Classics, Forty-two Chapters Classics, and self-narrative posts (a standard Huai Su Book). 3. Following a peaceful style of writing, such as Xiaocao's thousand-character writing, is quite different from his arrogant style of writing, and it has been completely transformed, which can also be said to be his outstanding point. Flowing clouds and flowing water, the heart is at the end of the pen, and the meaning is written first (this is especially important for cursive scripts, especially wild grass). Huai Su's "Weed Center" started writing, but there was no procrastination at the turning point, and the pen was broken.
