Tang Wenzong's three unique imperial seals refer to Li Bai's poems and songs.

In Tang Wenzong, Li Bai's poems, Zhang Xu's cursive script and Pei Min's sword dance were called "Three Musts".

Needless to say, the name of Li Bai's poems is widely read, and the name of "Poet Fairy" is not true.

Zhang Xu, whose characters are "Gao Bo" and "Ji Ming", is famous for his cursive script, and is called "Haystack". His poems are also unique, and he is good at the Seven Wonders, which ranks with Li Bai and How Ren as "Eight Immortals of Drinking". Together with He, Zhang and Bao Rong, they are called "four sons of Wuzhong".

Pei Min was born in the Kaiyuan period of the Tang Dynasty. According to "Strange Tales from a Lonely Studio", he "threw a sword into the clouds, dozens of feet high. If lightning shoots down, he will hold the sword in his hand and the sword will enter from the air, which will surprise everyone. " Therefore, it is called "blade master". According to "Famous Paintings of Past Dynasties", the painter Wu Daozi saw Pei Min's sword dance, so he "finished pestering monsters, and" made great progress with his pen ". Pei Min is famous for his good marksmanship. Punctuality, there are tigers everywhere in Peiping. He shoots 3/kloc-0 tigers a day.
