anecdoteEn: "In the fifth year of Dali (770), Du Fu was on his way to Chenzhou to投奔 his uncle Cui Wei when he encountered rising river waters and was trapped in Leiyang. Upon hearing the news, the magistrate of Leiyang County, Nie, sent someone to deliver wine and meat. Du Fu drank too much wine in the boat, and coupled with long-term poverty and illness, he unfortunately passed away at the age of 59. A generation of poetic sage thus fell, but his poetry will forever be passed down in the world."
