In ancient times, emperors would appoint envoys to travel the land investigating corruption and overseeing relief after natural disasters. Wangye worship in Taiwan features similar tours of inspection. Every three years Wen Wangye, the deity who presides at Donglong Temple in Donggang, Pingtung, is joined by five Wangye from the Heavenly Court. On behalf of the Jade Emperor, they conduct inspections, bestow blessings, and avert disasters before returning to Heaven.
