The poet of the Tang Dynasty who advocated combining articles for occasions and poems for events was Bai Juyi. According to the query of relevant public information, it is advocated that articles should be combined for the time and poems should be combined for things to be written. Juyi's "Classic Chanting and Spreading" interprets the realistic concern of classic poetry in the new era. "Articles should be combined for the time to be written, and songs and poems should be combined for things." This famous saying by Bai Juyi, a poet of the Tang Dynasty, means that scholars pay attention to the times and society.
