Chìdì (赤帝 "Red Deity" or "Red Emperor") or Chìshén (赤神 "Red God"), also known as the Nándì (南帝 "South Deity") or Nányuèdàdì (南岳大帝 "Great Deity of the Southern Peak"), as a human was Shénnóng (神农 "Farmer God" or "Plowing God"),[1] who is also the same as Yándì (炎帝 "Flame Deity" or "Fiery Deity"),[2][1] a function occupied by different gods and god-kings in mytho-history. Shennong is also one of the Three Patrons, specifically the patron of humanity (人皇 Rénhuáng), and the point of intersection of the Three Patrons and Huangdi.[1]
In response to Wuxing thought and Tu Shi, the founder of the Han dynasty, Liu Bang, is said to be the son of the Red Emperor; in the Han dynasty God of the Five Directions, the Red Emperor represents the Southern God. Among the Taoist deities, there are also deities that use the title of Red Emperor, such as Hung Shing.[citation needed]
The title has been used to refer to Yan Emperor,[3] Shennong[1][1][1], Emperor Yao[4] and Zhurong.[3]
He is also associated with Chīyóu (蚩尤), the god of some southern peoples, in both iconography and myth, as both Shennong Yandi and Chiyou fought against the Yellow Emperor, although Chiyou is traditionally considered more violent and has the horns of a fighting bull, while Shennong Yandi is more peaceful and has the horns of a plowing buffalo.[1]
He is the manifestation of the supreme God associated with the essence of fire; his animal form is the Red Dragon (朱龙 Zhūlóng) and his stellar animal is the phoenix. He is the god of agriculture, animal husbandry, medicinal plants and market.[5] In broader conceptualisation, he is the god of science and craft, and the patron of doctors and apothecaries.[1] His astral body is Mars.[6]
