Li Sao
"Fu" poetry is often viewed as a descendant of the "Verses of Chu" ("Chu ci" 楚辭) songs combined with the rhetorical expositions of the "Intrigues of the Warring States" ("Zhanguo ce" 戰國策). During the golden age of "fu" in the 2nd century BC, many of the greatest "fu" composers were from the southwestern area of Shu (modern Sichuan Province). A chapter of "Xunzi" containing a series of riddles has been theorized to be the earliest known "fu". The earliest preserved and definitely datable "fu" is Jia Yi's ""Fu" on the Owl" ("Fúniǎo fù" 鵩鳥賦), composed about 170. Jia's surviving writings mention an earlier "fu" he wrote upon his exile to Changsha which he modeled upon Qu Yuan's "Encountering Sorrow" ("Li Sao" ), but it has not survived to the present.
