If you just want to accumulate, of course, Poems of a Thousand Families is the best. If you want to study deeply, you can choose 300 Tang Poems compiled by Heng Tuju and 300 Song Poems compiled by Shangqiang villagers. . If it's just utilitarian, I can only recommend Mao Zedong's poems, which are easy to understand and enjoyed by elderly teachers.
We should really read Du Fu about love, friendship, affection and dreams. Liang Qichao said that he was a "lover". In fact, every poet has these feelings, and Du Lisu's works all contain these feelings. As for your aesthetic sadness, of course, Li Yu, Qin Guan, Li Qingzhao and Nalan Xingde are the best.
