The original meaning of "ancient poetry" refers to the poems written by ancient literati. Before and after Wei, Jin, Southern and Northern Dynasties, there appeared a number of five-character poems written by scholars before Wei and Jin, which had no title and no author. Most of them are lyric poems with unique expressive techniques and artistic styles, which are collectively called "ancient poems".
In modern society, the general ancient poetry refers to ancient poetry, and the poems before the Republic of China were all called ancient poetry.
Some people do some ancient poems in modern times, but they are only ancient poems, not ancient poems, so strictly speaking, ancient poems must have been written by ancient people.
