In fact, Tang Wenzong's Three Musts mainly refer to Li Bai's poems, Zhang Xu's cursive script and Pei Min's sword dance. I believe many people know Li Bai, but they don't know much about the latter two. Li Bai's poems and songs have been studied since childhood, and we naturally understand the charm and greatness of his poems, which is naturally called one of the three wonders of the Tang Dynasty, and it makes sense.
Of course, many people may not know much about Zhang Xu's cursive script, but for some people who are proficient in calligraphy, they naturally learned his cursive script, which can be described as flowing. However, his cursive script is particularly comfortable for people to look at, and it can also reflect the social development and social attitudes at that time. Relatively speaking, it also embodies the characteristics of calligraphy in the Tang Dynasty, and it can also have good value and significance.
Next is Pei Min's sword dance, but I believe many people don't know much about Pei Min. Pei Min is not only proficient in martial arts, but also adds artistic beauty to martial arts, which is why his sword dance became one of the three wonders of the Tang Dynasty. It is also attractive and artistic, and it is also of great significance for current research and study. Therefore, the three wonders of the Tang Dynasty are well-deserved, each with its own advantages and disadvantages.
