The origin is the Chinese traditional culture "Book of Changes". Hexagram 21 of the sixty-four hexagrams of the "Book of Changes": Fire and thunder bite hexagram. The meaning of its hexagram is: Difficulties will be solved quickly, obstacles will be eliminated, and the evil god of plague will be driven away with the meaning of thunder and fire.
In addition, in Chinese mythology, the fire god Zhurong (Emperor Ku) is a descendant of the Yellow Emperor. He and Lei Zhenzi, the leader of the Thunder Palace, are both gods of justice. Plagues are caused by evil gods, and justice defeats evil, so the names of these two hospitals imply the use of good to defeat evil.
In Chu culture, Hubei was the hinterland of ancient Chu, and the Chu people were considered to be descendants of the fire god Zhurong, so they also asked the fire god for blessing, which has a meaning of prayer.
Furthermore, according to the classification of the five elements, the lungs are gold, and pneumonia is evil metal. According to the principle of the five elements' mutual generation and mutual restraint, fire overcomes metal, so the name Vulcan hopes that fire can restrain the evil metal.
