What are the political lyrics?

In the early 1950s, the works of Guo Moruo, He Qifang, Hu Feng and others were all based on the emotion of praise, which created the artistic atmosphere of this issue of "political lyric poetry" and had a far-reaching impact on later creation. He Jingzhi's "Singing" and Guo Xiaochuan's "To Young Citizens" developed all the lyric elements of "political lyric poetry" into a relatively mature lyric model and became the representatives of the creation of "political lyric poetry" in this period. Influenced by it, Ruan, Wen Jie, Li Ying, Zhang Wanshu and others also wrote some long or short political lyrics.
