The current controversial point is narrowed to the point as to which period sekkobun was made in before the character standardization, and any one of Lord Ran (Qin), Lord Wen (Qin), and Lord Mu (Qin) is very probable and it is also considered that sekkobun was a poem made when Lord Xian (Qin) enjoyed hunting in B.C. 374.
現在の論点は、統一前の秦のどの時代に作られたか、に絞られており、襄公(秦)・文公(秦)・穆公(秦)のいずれかが有力視されており、献公(秦)の紀元前374年頃の巡狩の際の詩文とも考えられている。
