Among the poets in the prosperous Tang Dynasty, Wang Wei and Meng Haoran were good at five-character poems, while Wang Changling was good at seven-character poems. However, Li Bai is the only one who combines five poems with seven poems. 2. Pei _, a native of Kaiyuan in the Tang Dynasty, was also one of the "three wonders" in the Tang Dynasty.
