Why couldn't you ride a donkey in front of the county government in ancient times?

"Clothes and dust are mixed with wine marks, and sightseeing is fascinating everywhere. Is this a poet? Riding a donkey into the sword gate in the drizzle. " This is Lu You's masterpiece Rain at Jianmen Road. In the winter of the eighth year of Xiaozong Road in the Southern Song Dynasty (1 172), Lu You went to Chengdu from Nanzheng (now Hanzhong, Shaanxi) to serve as a member of the appeasement department, and then transferred to Chengdufu Road to serve as a member of the appeasement department. This poem was written when he went to Chengdu from Nanzheng via Jianmen. Since he is in office, he should ride a horse. Why did Lu You ride a donkey? The third sentence "this body is the poet's failure" is very strange, and the fourth sentence "riding a donkey into the sword door in the drizzle" is a wonderful answer. Although the poet asks himself and answers himself, it is meaningful and thought-provoking. Before Lu You, many poets in Tang and Song Dynasties, such as Li Bai, Du Fu, Chen Ziang, Gao Shi, Cen Can, Bai Juyi, Su Shi and Huang Tingjian, were all related to entering Shu. What does a poet have to do with riding a donkey? How did the animal donkey get together with the poet? This is a topic worth discussing.

The relationship between donkey and literature and intellectuals

Xu Shen said in Shuowen: "Donkeys are like long-eared horses; Meng, donkey also. " Donkeys are things that look like horses, but their origins, personalities and talents can't be compared with horses. It has a close relationship with literature, which can be traced back to the creation of poetry and fu in Qin and Han Dynasties, such as "Seven Cautions of Chu Ci": "What can I do if I ride an ass?" "The Songs of the South Zhao Zhu with Nine Feelings": "It is more and more useless to waste your ears." Calling a donkey "donkey" is a contempt for its irrelevance. In this poem, the donkey and the horse are in sharp contrast. They are all objects of sustenance. As natural and independent individuals, they have no necessary connection with the author. The fate of donkeys in cultural history can be described as bumpy. As soon as it entered literary works, it was despised by literati. Later, due to accidental opportunities, the situation gradually changed. Just as Gu said: "Take donkeys as a taste, Han will be famous, filial piety will be full of forests, and filial piety will be lucky." However, its species may come from outside the Great Wall. Since King Wuling of Zhao rode and shot, it has gradually been used by China. "
