"Zhongzhou Collection"
After the death of the Jin Dynasty, Yuan Haowen was captured along with a large number of officials, and was taken to Liaocheng, Shandong, where he was guarded for two years, and later lived in Guanshi County. As a prisoner, Yuan Haowen and his family moved to Liaocheng, Shandong and other places, and gradually established relationships with Yan Shi and Zhao Tianxi, the leaders of the Han army in Mongolia. His life gradually improved and he moved more freely. During this period, he was saddened by the fall of the Jin Kingdom and the traitors who misled the country. In order to preserve history with poetry, he diligently edited the "Zhongzhou Collection", a collection of poems by the late kings and ministers of the Jin Kingdom. The collection named "Zhongzhou" contains the deep meaning of remembering the motherland and using gold as its orthodoxy.
