"According to the Song dynasty history book Lushi, Chiyou's surname was Jiang (姜), and he was a descendant of Yandi. According to legend, Chiyou had a bronze head with a metal forehead. He had 4 eyes and 6 arms, wielding terrible sharp weapons in every hand, similar to a description of fangxiangshi. In some sources, Chiyou had certain features associated with various mythological bovines: his head was that of a bull with two horns, although the body was human, and his hindquarters were those of a bear. He is said to have been unbelievably fierce, and to have had 81 brothers." "Historical sources often described him as 'bold leader', as well as 'brave'. Some sources have asserted that the figure 81 should rather be associated with 81 clans in his kingdom. Chiyou knows the constellations and the ancients spells for calling upon the weather. For example, he called upon a fog to surround Huangdi and his soldiers during the Battle of Zhuolu."
"When the Yan emperor was leading his tribe and conflicts with Nine Li tribes led by Chiyou, the Yan emperor stood no chance and lost the fight. He escaped, and later ended up in Zhuolu begging for help from the Yellow Emperor. At this point the epic battle between Chiyou and the Yellow Emperor's forces began. The battle last for 10 years with Chiyou having the upper hand. During the Battle of Zhuolu, Chiyou breathed out a thick fog and obscured the sunlight. The battle dragged on for days while the emperor's side was in danger."
"Only after the Yellow Emperor invented the south-pointing chariot, did he find his way out of the battlefield. Chiyou then conjured up a heavy storm. The Yellow Emperor then called upon the drought demon Nüba (女魃), who blew away the storm clouds and cleared the battlefield."
"Chiyou and his army could not hold up, and were later killed by the Yellow Emperor. After this defeat, the Yellow Emperor is said to become the ancestor of all Huaxia. The Hmong were forced to live in the mountains and leave their Li kingdom. After Chiyou's death, it is said that it rained blood for some time." This story pertains to the battle between Michael and his angels and the Red Dragon and his angels. However, based from understanding who Michael really is, shows that it's not based on Huangdi, as there were changes regarding elements and story. Since finding the Aryans to have changed much of their old ways and mingling other cultures in, it becomes convoluted and hard to seperate them. At first I thought this story of Huangdi would be Michael, but that isn't case at all.
Here states this: "In the battle of Zhoulu, details the battle between the demon king Chiyou and the nine tribes against the Yellow Emperor’s forces which lasted 10 years. It is said that Chiyou breathed a thick heavy fog which covered the sunlight and conjured a heavy storm, but as the Yellow Emperor was assisted by another god; they were able to turn the tide of the battle thus defeating Chiyou and his forces. As the forces of Chiyou was forced to the mountains securing the victory to the Yellow Emperor, the story states that after Chiyou was defeated it rained blood for some days."
This resembles the 10-year war between the Gods and the Titans called "Titanomachy". Now, below shows that the Yellow Emperor pertains to "Saturn", while Chidi represents south and fire. Just as stated, the God called "Zhurong" is said to represent fire, and since Xuanwu and Heidi's stories are based on the legend of the fire deity battling the water deity, then it should be noted that this God pertains to fire symbolism and not the North.
As apart of the five heavenly Emperors, "Heidi" is shown to be the "Dark warrior" of the north, associated with water, winter, Mercury and is frequently revered as the supreme God of Heaven. (black dragon)
Then there is "Cangdi" who is known as the "Duke of the woods" who is associated with the east, wood, spring, Jupiter and is a fertility deity. (blue green dragon) This would resemble Shiva as he is the god of the pillar, and his wife Bixia as Kali. Then there is Baidi the white god who is associated with the west, metal, Autumn, and Venus. (white dragon)
Then there is "Huangdi" who represents the yellow dragon, August, Leo and Saturn. He is known as the Sun God and the four faced Creator. He is said to be the son of the virgin woman who comes out as the God of lightning and thunder. (Sounds familar?) This is the story of Buddha as "Thoth" being born in the same manner. Now, there is a movie on Youtube called "Xuan Tian Shang-di" or "Legend of Shang-di", as this details a God being born from a woman who couldn't get pregnant, and comes to live as a man on Earth. This is remiscent to the story of Vishnu becoming "Krishna" and God becoming "Jesus Christ". This is the story of "Huang-di" as Thoth or Hermes.
Then the last is Chidi as Yandi the red deity, who represents the south, fire, agriculture, science, craft, medicinal herbs and Mars. He is the Red dragon and the fiery phoenix.
