"Dianzhang" refers to Zhang Xu, a calligrapher in the Tang Dynasty. Zhang Xu's main works include Ziyan Tie, Four Poems of Ancient Poetry, Heart Sutra, Thousand-character Text, Bitter Bamboo Shoots Tie, Fish Eating Tie and Abdominal Pain Tie.
Zhang Xu, born in Wujun (now Suzhou, Jiangsu) with unknown date of birth and death, is called Zhang Changshi. According to the "Biography of Literature and Art in the New Tang Dynasty", "Xu, a native of Wu, Suzhou, is addicted to alcohol. Every time he gets drunk, he calls for going crazy, so he writes, or writes with his head soaked in ink. He wakes up and thinks that he is a god, and he can't get it back. The call Zhang Dian ".
Zhang Xu, Li Bai, He Zhizhang and others were called "Eight Immortals in Wine" at that time. His cursive script, together with Li Bai's poems and songs and Pei Min's sword dance, is also called "three unique".
Upset story:
Zhang Xu has a neighbor whose family is poor. Hearing that Zhang Xu is generous, he wrote to Zhang Xu, hoping to get his support. Zhang Xu was very sympathetic after reading the letter, so he said in his reply: "You can ask for hundreds of gold as long as you say that this letter was written by Zhang Xu."
After receiving Zhang Xu's reply, the neighbor took the letter to the street for sale according to his words, and it was quickly bought at a high price.
Zhang Xu's calligraphy skill is profound. Although he writes cursive script casually, all his works are organized. Among his works, Four Poems of Ancient Poetry is the most praised.
He wrote four ancient poems by Yu Xin and Xie Lingyun, two great writers in the Northern and Southern Dynasties, with the wild grass he created.
