范仲淹 《岳阳楼记》 (Northern Song, 1046), the canonical prose essay written at the request of his friend Teng Zijing, governor of Baling (modern Yueyang, Hunan). The famous middle declares:
予观夫巴陵胜状,在洞庭一湖 (As I behold the glorious scenery of Baling, it all lies in Dongting Lake). The essay's closing lines
先天下之忧而忧,后天下之乐而乐 are equally famous.
