Many classical books have lists and hierarchies of gods and immortals, among which the "Completed Record of Deities and Immortals" ( "Shénxiān tōngjiàn") of the Ming dynasty, and the "Biographies of Deities and Immortals" ( "Shénxiān zhuán") by Ge Hong (284–343). There's also the older "Liexian zhuan" ( "Collected Biographies of Immortals").
