When sekkobun was excavated in the early Tang period, the poems thereon which described the scenes of hunting were closely similar to the poems in 'Che-gong' and 'ji-re' of the Shi Ching, which paid a tribute to the King Xuan (Zhou) in Zhou and, therefore, it was considered that sekkobun was made in the period of the King Xuan in Zhou.
唐初期に出土した際は、狩猟を描写した詩歌が周の宣王(周)を称える詩経の「車攻」や「吉日」の詩と酷似していることから、周の宣王時代の作と考えられた。
