What were the so-called "Three Wonders of the Tang Dynasty" in Tang Wenzong's time?

The Three Wonders in the Tang Dynasty are related to the achievements of three great men in their respective fields, namely, poems written by Li Bai, fencing by Pei Min and cursive script written by Zhang Xu!

Pei Min was born in the Kaiyuan period of the Tang Dynasty. According to legend, after observing Pei Min's swordsmanship, Wu Daozi, a painter at that time, inspired himself and made a new breakthrough in painting. In addition, the great poet Wang Wei once wrote a poem praising Pei Min's superb swordsmanship, comparing him to a general from heaven. This shows what a state Pei Min has achieved in fencing!

Another poem by Li Bai, needless to say, we all know that Li Bai has a very important position in the history of China's poetry. He is a representative writer of China's romantic poems. Later generations praised him as a poet. Among the ancient poems, Wang Wei and Meng Haoran's five-character poems are well written, and Wang Changling's seven-character poems are also well written, but only Li Bai can write five-character poems well.

Zhang Xu said that not many people have heard of his name now, but his cursive script really occupies a very important position in the history of China cursive script. He and his eight people, including Li Bai, are all drinking! According to legend, Yan Zhenqing resigned twice in order to ask Zhang Xu for cursive script, just to learn calligraphy from Zhang Xu. Zhang is a very pure artist. He devoted all his emotions and energy to the creation of calligraphy, and he was indifferent to other things, but he was devoted to calligraphy.
