《资治通鉴·宋纪·宋纪五》
六月，丁丑，北魏国主拓跋焘的皇孙拓跋浚诞生。下令大赦，改年号为太平真君。因道士寇谦之的《神书》上有言 辅佐北方太平真君 ，所以采用这个年号。
六月，丁丑，魏皇孙浚生，大赦，改元太平真君，取寇谦之《神书》云 辅佐北方太平真君 故也。
In the eighth lunar month, there was a person with the character 丁丑, Northern Wei's Lord Tuoba Tao's grandson Tuoba Jun was born, and he ordered a general amnesty, changing the year name to Taiping Zhenjun. Because Taoist Kou Qianzhi's "Divine Book" mentioned "Assisting the Northern Taiping Zhenjun", so they adopted this year name.
