Where did Candle dragon, the God of Zhongshan in ancient China mythology, come from?

According to Shan Hai Jing, Candle dragon came from the northwest sea and lived in a very cold place in the north.

according to the records in the classic of mountains and seas, "the god of Zhongshan, named Yin Candle, regards it as day, blows it as night, blows it as winter, calls it summer, and doesn't drink, eat, rest and rest as wind. It is thousands of miles long. In the east of nowhere. It is a thing, a human face, a snake body, red, and lives under the Zhongshan Mountain. "

There is such a god in the north, named Candle dragon, alias Candle Jiuyin. Candle dragon is thousands of miles long, red all over, and looks like a human, but his body is in the form of a snake. His eyes are vertical and straight. When they are opened, it is daytime, and when they are closed, it is night. Candle dragon doesn't eat, drink or sleep. Blowing for winter, exhaling for summer, can call the wind and rain.

Extended information:

The holy spirit of Candle dragon looks very strange, with a human face on its head, but a long snake on its body, that is, a snake with a human face. His eyes stood upside down like olives, very bright. As soon as it is opened, the universe is illuminated like a day; As soon as my eyes closed, the night covered the earth. He just opened and closed, working endlessly for mankind. He breathed a sigh of relief and summer came; Blow a breath, the earth will be covered with ice and snow, and it will cycle back and forth in this rhythmic and regular breath all year round, and it will keep running.

The holy spirit of Candle dragon never eats or drinks, and he doesn't know where his strength comes from, so he is tireless and never has a rest. Sometimes, when he saw people suffering under the ground, he shed tears of sympathy. As soon as the tears fell on the earth, they turned into rain, nourishing the growth of all things in the universe. Candle dragon's holy spirit not only benefits all things in the universe, but also often holds a candle in his mouth. The candle shines in the Tianmen, illuminating the heavens and the earth, and making selfless contributions to all things in the universe endlessly.
