In 1998, Shandong University became one of the first universities which obtained the master's degree conferral right for folklore. In 2002, Shandong University obtained the doctor's degree conferral right for Chinese folk literature. The doctoral program has three research directions: folk literature, the history of Chinese folk literature, folklore and folk narrative.
