Xiao Tong
During the Six dynasties era, Guo Pu wrote "fu" during the Eastern Jin dynasty. In the field of criticism and "fu" authorship, Lu Ji's's "Wen fu" is an important work, which was later rendered into English by Achilles Fang. The "Wen Xuan" anthologized by "Xiao Tong" (501–531) is an important source work for surviving "fu", including "fu" which he attributes to Song Yu.
