Who is the Tang Dynasty calligrapher who called Cao Sheng by his famous Wild Grass?

Huai Su (737~799), an outstanding calligrapher in the Tang Dynasty, was known as "Cao Sheng" in history. Zang Zhen, a monk named Huai Su and a common surname Qian, is a native of Lingling, Yongzhou, Hunan, and is the nephew of Qian Qi, one of the ten gifted scholars in Dali. [2]

He became a monk in his early years and devoted himself to cursive writing in his spare time. He is as famous as Zhang Xu, and is called "Proud", which formed the coexistence of two peaks of calligraphy in the Tang Dynasty, and also two peaks in the history of cursive script in China. Huai Su's cursive brushwork is fine and vigorous, flying naturally, like a whirlwind of showers. Calligraphy is changeable, changeable and has legal standards. Li Zhimin, a pioneer and professor who inspired others to enter the grass, commented: "Huai Su cursive script has a delicate spirit in galloping and a pure and gentle spirit in wild". [ 1]

Calligraphy works handed down from ancient times include Autobiography, Qianzicao, Bitter Bamboo Shoots, Notre Dame, Lun Shu and so on. [2]
