Later he moved to Beijing, where entered the university at advertisement faculty. Being bored at studies, Ren started photography, taking pictures of his friends. At this time young man realised that he was not at all interested in university studies - photography interested him much more.
So in 2008 Hang began his photography, starting to shoot a naked roommate in a dormitory. Firstly, his models were friends, and then fans who quickly discovered his works. The young man was self-taught and was taking pictures without any purpose, admitting that he was simply shooting what he sees.
Over the time, he gained fame for his staged erotic photographs, whose models were young Chinese actors and fashion models. Often, he invited friends to participate in group photo sessions and even shot his mother in one of his series with a pig's head.
