This song is for a charity campaign sponsored by Music Radio & CCTF (China Children & Teenagers Fund) called "我要上学" (I want to go to school). Its aim is to help poor children in remote areas of education.

Jolin is supposed to sing in this, but I can't hear her voice o_O

Several Warner artists participated to this: JJ Lin, Jam Hsiao, Tiger Huang, Khalil Fong...
