It details his journey to China after college to study Chinese wu shu, better known in the west as kung fu, and to teach English. Though not trained as an actor, Salzman starred as himself, as did Pan Qingfu, who claimed no one else could portray him on film. Salzman's experiences occurred in Changsha, Hunan, though the film was shot in Hangzhou, Zhejiang. (Wikipedia)
