He made his first feature film Tang shi (Tang Poetry, 2003) two years later. His drama Mang zhong (Grain in Ear, 2005) attracted the attention of the international audience. Afterwards he made Hyazgar (Desert Dream, 2007), which he filmed in the Mongolian desert. In 2008 he produced his first film, Huangjin zhou (Routine Holiday, 2008) directed by Hongqi Li. In that same year he directed his two dramas Iri (2008) and Chongqing (2008). Currently his last feature film is Dooman River (2010), made in coproduction with France. He also made a documentary Pung-gyeong (Over There, 2013).
