In the Ming Dynasty, publishing the edict proclamation was an important way to disseminate the imperial decrees. Although the central institutions were the issuing entities, the basis and main content of the proclamations were still the emperor's edicts. From the functional point of view, the edict proclamation was mainly used in the aspects of comforting the military and civilians, publicizing policies, and rectifying education, etc. Its openness and convenience helped the central court and the government at all levels to rapidly implement the policies and maintain the social order. In addition, the unified form of the document and the relatively flexible transmission path enabled the complete reproduction and widespread dissemination of the sacred edicts within the territories governed by the Ming Dynasty.
