魯文伯之母敬姜所言的“社而賦事”，點明了在社祀時賦事功能的方式，可以作爲觀察賦事制度運行的入口。周代賦政系統中，賦職事、政事的實踐不斷功能化、抒情化，促成了賦法的完善。《夏書》所言的“賦納以言”傳統，强化了賦言的藝術性。賦政、賦事機制對賦法、賦詩的促成，是研究賦法起源與形成不可忽略的歷史語境。

She er fu shi, said by Jingjiang, the mother of Wenbo of Lu, points out the functions and fashions of assigning duties during communal worship, which can serve as the entry point for observing the working of the system of duty assignment. The increasing functionalization and lyricization of the assigning of official duties and government affairs in the administrative system of the Zhou Dynasty had contributed to improving the fu fa (rhapsodical technique). The fu na yi yan (heeding verbal advice)tradition recorded in Xia shu (Book of Xia) emphasizes the artistic quality of fu yan (the use of words in rhapsody). Therefore, how the assigning of official duties and government affairs had contributed to the emergence of fu fa and fu shi (rhapsody)is an unignorable historical context for the studies of the formation of fu fa.
