The impression of the current seal can be found in the Jiaqing Emperor’s Baosou, compendium of seal impressions, and the size and material recorded in the compendium match that of the current seal. Notably the compendium states clearly that the seal is made of tianhuang, and belongs to a set of three seals, the other two seals reading shanli wanwu and zhenzhuo baijia (see Qingdai dihou baoxi yinpu, vol. 9, Jiaqing (II), Beijing, 2005, p. 200). As such the current seal was part of an imperial set that once belonged to the Jiaqing Emperor.
