Which period of poetry is included in Poems of a Thousand Families?

Thousands of poems are old-fashioned reading materials. There are two kinds of poems, namely, newly carved five-character poems and rewritten thousands of poems. The former is about Wang Xiang's notes, while the latter is about Xie Fangde's notes and Wang Xiang's notes, both of which are seven-character poems. The two anthologies are divided into quatrains and metrical poems, most of which are works of Tang, Five Dynasties and Song Dynasty, especially the Song Dynasty. Because the selected poems are easy to understand, they are widely circulated.
