it feels like a kind of joke when I was a high school student 5 years ago. It was really popular among us and students shouted "信春哥,不挂科" [Believe in Brother Chun, Don't Fail!] when teachers were to give out exams papers. That is the only ritual.
I'd love to know this following became self-consciously, if parodically, religious - what images of religion fed into it, etc. I'm intrigued also because of the gender switch at its center. Apparently the step from brother Chun to eternal life (and then on to more pressing things like exam success) was the formula 铁血真汉子,春哥纯爷们 Made of Iron and Blood, Chun Ge is Pure Male, often posted with photoshopped pictures of Li's head on a muscled male body.
This is no more "really religious" than the Flying Spaghetti Monster religion, but that doesn't mean it isn't interesting from a religious studies perspective. And it wasn't just students invoking Li's co(s)mic gender switch. Apparently signs were also seen on condemned buildings with the words: 信春哥 房子不会被拆 Believe in Brother Chun, House Won't Be Demolished. More than parody's going on there.
