Huai Su (725-785) was a grass saint. People in the Tang Dynasty, whose words are hidden in truth, are named Huai Su, whose common surname is Qian, Han nationality, and Lingling, Yongzhou (Lingling, Hunan). A good Buddha at an early age makes a monk. He is a leading generation of coquettish cursive script writers in the history of calligraphy. His cursive script is called "Crazy Grass", which is round and powerful with a pen, making it turn like a ring, bold and unrestrained, smooth and in one go, just like Zhang Xu, another cursive script writer in the Tang Dynasty, and is called "Zhang Dian Su Kuang"? Or "get drunk."
The poet Mo Ke throughout the ages praised Huai Su's achievements in cursive writing. Li Bai, a great poet in the Tang Dynasty, once sang poems in praise of Huai Su's cursive script: "Young people are called Huai Su, and cursive script is called unique in the world. Mo Chi flies out of the northern style fish, and the pen tip kills all the rabbits in the mountains ... "(A Cursive Song) Han Wo's Cursive Screen of Huai Su also praised:" Where there is a screen, it is clear that Huai Su is lying. Although it is dusty, it is especially thick with ink marks. Strange rocks rush to the autumn stream, and cold vines hang Gu Song. If you teach the water, every word will be a dragon. " Guan Xiu's "Viewing Huai Su's Cursive Song": "Zhang Dian was bumpy, and it was bumpy until the top of Huai Su. Teachers don't talk about Zen without talking about scriptures, but their strength is only in cursive script. Crazy but afraid of being a fairy, God can help you, and stone painting and ink must enter. The golden statue of bamboo leaves is more than a bucket, and it is half drunk and half wet. Drunk and fierce as a tiger, the powder wall screen does not ask the Lord. ..... knowing that the name of the master is in the world, what is the pole of the moon and the breeze? " General Manager Lu's Continued Book Review said: "Huai Su cursive script, with the help of electricity, changes at will." Huang Tingjian's "Inscription and Postscript of the Valley" said: "Huai Su's cursive old age is not diminished (according to Zhang Xu). Covering Zhang Miao is better than fat, and hiding is really better than thinness. These two people are also the crown of a generation of cursive scripts. " Mi Fei's "Haiyue Book Review" praised "Huai Su's book is like a strong man's sword, and the color of the gods is moving, but it is always in the middle of the festival." A certain person's Collection of Ancient Records also said: "Zangzhen was famous for its cursive script at that time, and it was especially rare in this world." Jiang Zhiqi commented: "The cursive script is wonderful, and Huai Su can win it." Cen Zongdan's Book Review also described "Huai Su's leisure, so he is like a true fairy." Shen You's Inscription and Postscript on Calligraphy and Painting explained: "Huai Su's book is so wonderful, although it is full of changes, it will never leave the Wei and Jin Dynasties." Wang Shizhen's A Mountain Man's Draft in Yizhou praised Huai Su's Thousand Essays, saying that "every word wants to be immortal and the pen wants to fly". In March, 217, scholar Huang Jinxiang first discovered the original paper copy of Huai Su's "Thousand Characters of Grass", which had been lost for a long time, and praised: "A simple monk walks alone, and the grass is sacred for a thousand years. God reappears, and the country is blessed! " There are even more comments from calligraphy connoisseurs, and there is hardly a book on calligraphy history that doesn't mention Huai Su.
