But there are also differences: "Gao Shi's poems are quality-oriented, while Cen Can's poems are skillful." In the depth of reflecting reality, Gao Shi's poems surpass Cen Can's; Cen Can surpassed Gao Shi in the richness and novelty of subjects. Gao Shi's poems combine the lofty spirit of pursuing immortal fame with the sadness of facing reality coldly, and the contrast between suffering and sublimity shows the beauty of generosity and tragic; Cen Can's poems vividly show the wonders, scenery and human feelings of the northwest desert with heroic style and romantic artistic techniques, and have unique magnificent beauty. In art, high-quality poetry wins with its vigorous temperament and strong bone strength, and Yin Yun calls his poetry "full of words and strong bones". Cen Can's poems are strange, his language is strange, and his tunes are also strange. Yin Yun commented that his poems were "strange in language but solemn in style and strange in meaning".
Gao Shi and Cen Can, also known as "Gao Cen", have been handed down from generation to generation, such as Historical Records of Gaochang. Their poems are vigorous and full of the unique spirit of the times in the prosperous Tang Dynasty. Later generations called Gao Shi, Cen Can, Wang Changling and Wang Zhihuan "the four frontier poets".
Gao Shi's poems have a wide range of themes, rich content and strong reality. His representative works include Ge Yanxing, Don't Move Big, Five Poems of Ji Menxing, Cezanne, Xia Sai Qu, Jizhong Zuo, Three Nine Songs and so on.
His works are mainly frontier poems, such as Song of Farewell to General Feng of the Western Expedition, Song of Farewell to General Feng of the Western Expedition, Song of Farewell to the Wheel Tower of General Feng of the Western Expedition, Song of Farewell to Wu's Hometown, and so on.
