刘裕派一个代表到朝廷接受这个奖励，并问候皇上的生活。延之和他的同事王参军一起回使京城，经过洛阳，延之在路上作诗二首，这诗的语言非常丰富和华丽，谢晦与傅亮见后非常赞赏。
义熙十二年，高祖北伐，有宋公之授，府遣一使庆殊命，参起居；延之与同府王参军俱奉使至洛阳，道中作诗二首，文辞藻丽，为谢晦、傅亮所赏。
Liu Yu sent a representative to the court to accept the reward and greeted the emperor's life. Yan Zhi and his colleague Wang Sanjun returned to the capital together, passing through Luoyang, and Yan Zhi wrote two poems on the road. The language of the poems was very rich and gorgeous, and Xie Hui and Fu Liang praised it very much after seeing it.
