A collection of poems that does not belong in the history of modern Chinese poetry is?

The collection of poems that does not belong to the history of modern Chinese poetry is Red Flag Ballads. Red Flag Ballads is a collection of some of China's classic red songs, most of which are based on Chinese folk ditties, folk songs, folk tunes, etc., so it is not considered a collection of poems in the history of modern Chinese poetry.

The general principle of "Songs of the Red Flag" is to record the songs straight from the original text without modification. There are a few chapters in which individual words and phrases have been altered and embellished without damaging the style of the original work.
