 You Xiaoxi (Seaouke Yue) sold several objects that were part of Duanfang's collection from 1916-1919; he acquired these objects through the family of Duanfang. Seaouke Yue cites the Duanfang provenance in documentation from the American Consular Service, see:

This object is included in the inventory of box II as number 63. In this certificate, Yue states that he acquired from the Duanfang [Tuan Fang] collection in October of 1918.
