Chu Ci
The "Chu Ci" was compiled and annotated by Wang Yi (died AD 158), which is the source of transmission of these poems and any reliable information about them to subsequent times; thus, the role which Qu Yuan had in the authoring, editing, or retouching of these works remains unclear. The "Chu Ci" poems are important as being direct precursors of the "fu style" of Han Dynasty literature. The "Chu Ci", as a preservation of early literature, has provided invaluable data for linguistic research into the history of the Chinese language, from Chen Di on.
