Can you tell me a famous saying about yuan dynasty history?

Poetry in Yuan Dynasty (including words and songs) is unique. In order to restrict the participation of Han people in politics, the imperial examination was abolished for nearly 80 years from the ninth year of Yuan Taizong (1237), which made scholars who wanted to enter the imperial examination lose hope and their status plummeted. In addition, most of the poets in the early Yuan Dynasty entered the Yuan Dynasty from Song and Jin, and their adherents had a strong color. Therefore, on the one hand, the poetry of the Yuan Dynasty always reveals the thoughts of the old country and the feeling of vicissitudes; On the other hand (mainly in Yuanqu), the number of works lamenting the impermanence of the world, lamenting the thorns in the world, and abandoning the world to live in seclusion has increased obviously, and the language is absurd, showing the author's negative and gloomy mentality. The former is represented by Ye Lv Chucai's Feeling of Crossing the Qin Garden, Fang Hui's Song Lizong Book Gongshan Baigou and Zhao's Tomb of Wang Yuee. The latter, represented by Ma Zhiyuan's Double Tone Break (Ovary Shoes, Buying Minister Wood), Guan Yunshi's Double Music Palace (Loyal Minister, Jumping Guluo River) and Zhang's Zhong Lu Le (Li Chu Sao, who can explain), is unique in historical poetry.
