The Tai Di has been represented in various ways, at different times and in different contexts, according to the contextual sensibilities: in Taoist theological thought the Jade Emperor (Yu Di), Taiyi Tianzun (the "Great Oneness"), Hongjun Laozu ("Ancestral Master of the Great Duality"), or the undefinable Tao; in mythological thought Yu the Great; in Chinese folk religion and Confucianism Tian (the "Great All" or the "Universe") or Shangdi (the "Highest Emperor").
