The original song of "The Wild Singing of a Restless Heart" was sung by Ni Hong, written by Zhang Youlun, composed by Ouyang Shangshang, produced by Mainland China, arranged by DJheap for nine days, produced by Mr.Tao, coordinated by Huang Yan, and produced by Shanghai Yixiang.

Some lyrics of the song: My restless heart, I want to sing wild. Who knows how much sadness there is? You can see that I have to bow my head to life like a layman in the world. I want to sing wild in my restless heart. Who knows how many tears are hidden here, and then I will fill it with bitter and spicy spirits and light my cigarette.
