Monty Tie and Hans Zhang Tie are the most famous. All other calligraphy styles are poor. Zhang Huaiguan said in the Book of Broken Tang Dynasty: "The eight forms of inquiry are perfect, and the brushwork is dangerous and energetic. The Indian style is particularly fine, flying white, as strict as the ancients. Like a dragon and snake fighting, the clouds are light and the wind is light. The wind whirls and thunders, and exercise is like a god. The decay of the true line comes from the big order, so don't become one. As dense as an armory spear and halberd, Shen Feng is stricter than wise water and less polished than Shinan. Its cursive script is circulated, which can be regarded as two kings. It can be used as a dynamic color, but it scares him to jump, does not avoid danger, and hurts elegance. " ? Yu Shinan said that he "can get what he wants without choosing a pen and paper". Besides, he can write a good official script. In the fifth year of Zhenguan, the tablet of Xuzhou Cishifang was his official script. His calligraphy, with official script as the most. Examining its pen, it is both round and powerful. "Surprised in the grass, sending between clouds. Another example is King Kong glaring and Lux punching. " The inscription he wrote on the Buddhist stupa of Huadu Temple, the inscription on the grandfather Wen Yanbo and the inscription on Huangfu's birthday are called "the first regular script in the Tang Dynasty". Among them, strokes such as vertical hook are still official strokes. His regular script has a very serious procedure, both in pen and structure, which is most convenient for beginners. The Thirty-six Methods of Ouyang's Structure, which was circulated by later generations, is a structure writing method summarized from his regular script. His regular script "Zhang Hansi's Lu Tie" is long and vigorous. Ink handed down from generation to generation is especially precious. Ou Yangxun's son Ouyang Tong has a family of calligraphers. Both father and son are very famous in the book world and are called "Ouyang". Xiao Ouyang's "Taoist Monument" has a stronger sense of propriety, but it is too revealing and implicit. ? Ou Yangxun's calligraphy was famous in the world as early as the Sui Dynasty, and spread abroad. When I entered the Tang Dynasty, people and books were old and perfect. However, Ou Yangxun himself was not satisfied with his achievements, and he continued to learn and improve. ? On one occasion, Ou Yangxun went out for sightseeing and saw an inscription on Cao Zhang written by Suo Jing, a calligrapher in the Western Jin Dynasty. After reading it several times, he thought it was average. But on second thought, since Suo Jing is a generation of calligraphers, his books will also have their own characteristics. Why not let me get to the bottom of it? So I stood in front of the monument and looked at it several times, only to find the profound and wonderful place. Ou Yangxun sat down beside the stone tablet and groped for three days and nights. Ou Yangxun finally realized the spirit of Suo Jing's calligraphy pen, so calligraphy became more perfect.
