"Spring River Flowers and Moonlight Night" is an old title of Yuefu's "Qing Shang Qu Ci·Wu Sheng Songs". There are different opinions on who the creator was. It may be said that "the origin is unknown"; it may be said that it was done by empress Chen; or it may be said that it was done by Emperor Yang of Sui Dynasty. According to Guo Maoqian's "Collection of Yuefu Poems", in addition to Zhang Ruoxu's poem, there are two poems by Emperor Yang of the Sui Dynasty, one by Zhuge Ying, two by Zhang Zirong, and one by Wen Tingyun. They may appear to be narrow in layout, or may appear to be too rich in makeup, far inferior to Zhang Ruoxu's piece. This old title, in the hands of Zhang Ruoxu, suddenly became brilliant and gained immortal artistic life. To this day, people no longer even try to find out who the original creator of the old title is, but attribute the real creative power of the title "Spring River Flower Moonlight Night" to Zhang Ruoxu.
