Who is the initiator of the new Yuefu movement and the successor of the realistic tradition?

The New Yuefu Movement and the Poetry Innovation Movement were initiated by Tang poets Bai Juyi, Yuan Zhen and Zhang Jihe Jincon. They advocated restoring the ancient system of poetry collection, carrying forward the tradition of satirizing current events in The Book of Songs and Yuefu in Han and Wei Dynasties, and making poetry play the role of "monitoring current events" and "releasing human feelings", emphasizing writing current events with the theme of new Yuefu created by themselves, hence the name. The so-called new Yuefu is relative to the ancient Yuefu. Guo Maoqian in Song Dynasty pointed out that the new Yuefu was a new song in Tang Dynasty. With its words, Yuefu has never heard of it, so it is called Xinle Yuefu.
