"Huang Liang has had a dream for twenty years, but he still doesn't know how to love or please." Xu Song's fourth album is called "Sleepwalking Plan". Liu Zi borrowed a homophone here to describe his pursuit of stars over the years as a dream. Da Song, if you walk into my dream and give me tenderness, I would rather never wake up in this life. Here there is the inspiration of poor students, the lingering love, the youthful and blushing campus, the turbulent officialdom, and the madness of chasing stars. If you have never been crazy about your idol, is your youth a little less colorful?
