The earliest record of Shenshu and Yulü occurs in a passage quoted from
Shanhaijing (;
Classic of Mountains and Seas) in
Wang Chong (d., c. 97 AD)'s
Lunheng (, "Discourses in the Balance", although the passage is not found in surviving recensions of the
Shanhajing, and another corroborative source of this period,
Ying Shao's
Fengsu Tongyi ( 195) These sources add that the decorations are put up on
New Year's Eve, or to quote more literally "the night before the La rites" (La 臘; held at the end of the year; precursor of
Laba Festival). The peach figures, also called
taogeng () are wood carvings. This legend has been commented on as the traceable
origin myth for the cult of the posting of the
Menshen gate deities, and in later times, different deities have superseded them as gate gods to a large measure, but regionally, Shenshu and Yulü still continue to be employed as the New Year's guardian gate gods. == Later history ==
