From the opening of
李白 《将进酒》 (Bring in the Wine, mid-8th c., Tang):
君不见黄河之水天上来,奔流到海不复回 (Do you not see? The waters of the Yellow River come down from heaven, rush to the sea, and return no more). The greatest drinking-song in Chinese poetry and one of Li Bai's supreme performances. The opening couplet links cosmic river-flow to personal mortality.
