Poems?
I deleted the poems because according to the note, it seems that they are directly quoted from unpublished manuscripts instead of published papers. It is very problematic because Reliable sources says that we can only use "published sources". If they are published in academic papers or books, we need to clarify the references. --saebou (talk) 11:25, 29 January 2020 (UTC)
