Gao Xianzhi
In 749, Cen's ambitions lead him towards a stint of military service which would last about ten years, where he served as a subordinate to General Gao Xianzhi, and, later, Feng Changqing. In about 751, Cen met Gao Shi and Du Fu, and the three had become good friends. All three were poets. Cen's other friend was the great Tang poet Li Bai, who composed a poem titled "Bring in the Wine", and included a verse which mentioned his friend Cen Shen. ..."To the old master, Cen"... Bring in the wine! Let your cups never rest! Let me sing you a song! Let your ears attend!"
