Yin He refers to Yin Keng and He Xun, two famous poets in the Liang and Chen eras of the Southern and Northern Dynasties. They are both good at writing new-style poems. They have worked hard on choosing words, sentences and rhymes, and their poetic styles are relatively similar. Du Fu once wrote a poem, "Who knows that the two Xie generals are capable of doing things, why should they bother to study hard?" ("Relief from Boredom"), expressing admiration for their spirit in refining their poems. The contents of their poems mostly describe landscapes and scenery, and the style of their poems is fresh and graceful. He Xun was born earlier than Yin Keng, and the dates of his birth and death cannot be determined. About AD 518. Xun, whose courtesy name is Zhongyan, was born in Tan, Donghai. His works are not many, but his poems are meaningful, his artistic conception is fresh, his style is similar to that of Xie Yi, and his style is closer to Tang poetry than other Yongming style writers. For example, "The evening birds have gone to the west, and the remaining clouds have also half disappeared. The wind stirs the dense bamboos, and the water shadow hides the long bridge. Travelers are worried, and the cold river is lonely again." ("Evening Bridge on the River") is quite refreshing. There are also "Farewell with Hu Xing'an at Night", "Farewell", "Gift to Zuo Cheng", "Xiaxiashan", etc., which are clear and natural, with a grateful style. Yin Keng, the date of birth and death is unknown. Keng, courtesy name Zijian, was born in Wuwei in the Southern Dynasties. In Chen Shi, he was the prefect of Jinling and a regular attendant of Yuanwai Sanqi. The poetry style is bright and fluent, but the content is relatively narrow, mostly about the scenery of mountains and rivers. He was a little later than He Xun, and the poems he wrote basically conformed to the rhythm of rhymed poetry. The more famous one is "Crossing the Green Grass Lake", in which sentences such as "The sky is clear and green, reflecting the sun's floating light" are quite vivid, and there are also sentences such as "The mountains and clouds are far away like a belt, and the garden leaves are close to forming a boat." (Xianju pairs Rain)) "The fog in the night river is vast, and the new moon is shining brightly." ("Five Continents at Night") all show the author's ingenuity and "painstaking efforts".
