The reason why Li Bai can't be one of the eight great writers in Tang and Song Dynasties is that the eight great writers in Tang and Song Dynasties are the collective names of eight representative essayists. Li Bai's main achievement is poetry rather than prose, so he is not the eight masters of Tang and Song Dynasties. The eight masters in Tang and Song Dynasties were Liu Zongyuan, Ceng Gong, Wang Anshi, Ouyang Xiu, Su Shi, Su Zhe, Su Xun and Han Yu.

Li Bai, nicknamed Qinglian lay, was a great romantic poet in Tang Dynasty, and was later called "Poet Fairy". When I was young, at the age of 24, I "took my sword to the countryside and traveled to relatives." In the early days, Li Bai's official career was not smooth. Later, he met He. After recommending Li Bai, he was appreciated by Emperor Xuanzong of the Tang Dynasty. Li Bai was ordered to worship the Hanlin. After the Anshi Rebellion, Li Bai exiled Yelang. That year, Li Bai was 58. Later, despite the drought, the court pardoned Li Bai, but the old Li Bai lived an embarrassing life. On the third day of last year, Li Bai, who was seriously ill, finished writing Dying and died. Li Bai mainly lived in the prosperous Tang Dynasty. He is generous and loves the mountains and rivers of the motherland. He traveled all over the country and wrote many magnificent poems praising famous mountains and rivers. There is a strong sense of self in his poems, and he likes to describe himself with magical scenes, and his emotions are reflected in his poems. Although Li Bai was not one of the eight masters in Tang and Song Dynasties, his style was different from that in Tang and Song Dynasties. His literary achievement in poetry is the "first" poet in the prosperous Tang Dynasty, which has a far-reaching influence on later generations.

Li Bai's creation of poems and songs can be said to be the best in the world, which has great influence on later generations. But Li Bai's achievement mainly lies in himself, because Li Bai is a great romantic poet. However, in history, he did not set off a literary revolutionary movement like poetry. In contrast, the winners of the Eight Masters in Tang and Song Dynasties, in addition to their own literary achievements, also set off a more important literary movement in the society. In the Tang Dynasty, Han Yu and Liu Zongyuan rose in Zhenguan and Kaiyuan, and at that time, an ancient prose movement was set off in society, which made the prose in the Tang Dynasty develop to a climax. ?

As far as poetry creation is concerned, Li Bai is the first master in the world, but he has never initiated or led a cultural movement in the field of poetry and prose.
