What is the relationship between Weng Zhifei and the imperial edict of Yanta?

Weng Zhifei is an excellent interpreter of the preface to the sacred instruction of Yanta. Weng Zhifei first gave a concise explanation and detailed and in-depth analysis of the preface to the sacred teachings of Yanta itself, which was simple and clear. In the process of explanation, supplemented by charts, it is more simple and clear. This dual combination of illustrations and words left a vivid impression on others.
