Jiangyi

The jiangyi is the most elaborate of the vestments a Daoist high priest wears to preside at the jiao, the great communal offering ceremony, and its name is usually translated as robe of descent, referring to the deities the priest calls down during the rite. Made of embroidered silk, its imagery is drawn directly from Daoist cosmology, commonly including symbols of the Big Dipper, the eight trigrams and paired cranes or other longevity motifs, so the robe itself functions as a wearable diagram of the cosmos the officiant is ritually moving through, not merely as ornament.

Schipper's study of the Taoist body describes the presiding priest at a jiao as, in a real liturgical sense, embodying the Dao during the rite, and the jiangyi's imagery supports that role visually, marking out its wearer as standing at the center of the cosmological order being enacted. Only the presiding priest of high rank wears the full jiangyi; assistant priests wear plainer vestments appropriate to their supporting parts in the liturgy. The specific combination of motifs is not left to an embroiderer's taste; ritual manuals and workshop tradition together specify which figures belong on a jiangyi of a given rank, so two robes made centuries apart for priests of the same standing are recognisably the same design.

Liturgical use of an elaborate embroidered vestment of this kind is attested in Daoist ritual manuals from the Tang and Song dynasties, and the essential form has continued through the Zhengyi and Quanzhen traditions into the present, principally among the ritual masters of the Zhengyi lineage who conduct the jiao and related community rites for lay clients. Making a jiangyi is skilled and costly work, since the embroidery must render specific cosmological figures correctly rather than as generic decoration, and a priest's robe is treated as a serious ritual instrument in its own right, stored and handled with the same care given to the priest's other liturgical implements.

The Taoist Canon, the historical companion to the Daozang compiled by Schipper and Verellen, documents the ritual manuals that specify vestment and procedure together, underscoring that in Daoist liturgical practice what a priest wears is not incidental to the rite but part of its correct performance, on the same footing as the texts recited and the gestures made. Surviving examples and photographs held in museum and temple collections, together with the ritual manuals collected in the Daozang, are the main evidence scholars use to trace how the garment's specific embroidery patterns have and have not changed across the centuries.
