Zhu Rong, whose real name is Li Zhong, is an ancient mythological figure in China, named Chi Di, and later generations respectfully call him Vulcan. Some people say that Zhu Rong is Huang San, one of the three emperors and five emperors in ancient times. According to Shan Hai Jing, Zhu Rong's residence is the end of the south, which is his way of spreading fire and teaching people how to use it.
On the other hand, Zhu Rong was Gao Xin's fire officer and was named Zhu Rong by the Yellow Emperor. In everyday language, Zhu Rong is synonymous with fire. Some newspaper headlines often mention that Zhu Rong is synonymous with fire, although this is a misunderstanding.
Zhu Rong's image:
According to Shan Hai Jing Overseas South Jing, Zhu Rong is in charge of the south, with a human face and an animal heart, riding two dragons. There are still many records about Zhu Rong in Shan Hai Jing, most of which don't describe the image too much.
However, Zhu Rong's image in the Chu Silk Books of the Warring States unearthed in modern times is quite different from that described in Shan Hai Jing. The image of Zhu Rong in Chu Silk Book is consistent with some legendary images.
Therefore, what we now think of as Zhu Rong's image is actually a combination of myth, history and folklore. There is no unified image. This may be because he was originally a god created by ancient people to represent summer and the south.
