诗经
It is believed that Confucius did encourage his followers to study the songs contained in the "Classic of Poetry", helping to secure the "Classic of Poetry"'s place among the "Five Classics". After Confucian ideas became further entrenched in Chinese culture (after about 100 BCE), Confucius's endorsement led many scholars to study the lyrics of the "Classic of Poetry" and interpret them as political allegories and commentaries.
