I don’t know whether you want poems and songs or about ancient classical Chinese. I recommend this to you: 1. Classical Chinese "Gu Wen Guan Zhi", www.xigutang.com/guwen recommends checking out this kind of website ; 2. Poetry, lyrics, and poetry. Yu Pingbo studied the poetry of the Tang and Song dynasties in the 1930s and 1940s.
I hope it will be helpful to you and I will give you satisfaction
