Dragons in the east often spray water, while dragons in the west usually spray water. The flames in their mouths are enough to melt stones. Although there is some strong acid and cold, the smell of fire is a typical image of Xilong and the most representative. As for why dragons breathe fire, medieval Europeans made the following interesting speculation: dragons often swallowed a phosphorus-containing ore and stored it in their stomachs. When necessary, they turn it into a gas, which will burn when it comes into contact with oxygen. This is obviously inspired by the cow's back nozzle, which is similar to the working principle of modern flamethrowers. However, according to the theory of traditional Chinese medicine, dragons may eat everything, and then there are stones in their stomachs, which leads to indigestion and inflammation of the liver fire. In fact, the fire-breathing dragon is one of the most common monsters in the book of death in ancient Egypt more than 3000 years ago. With the conquest of ancient Egypt by ancient Rome, the image of fire-breathing dragon also penetrated into western mythology, which is the earliest origin of western fire-breathing dragon.

The latter is called in English? Dragon? What's the Chinese name? Dragon? Or? Dragon? Or? Poisonous dragon? . It symbolizes the soul of violence and evil.
The dragon mainly represents good, while the west dragon mainly represents evil. Dragon is the spiritual and cultural symbol of the Chinese nation. It is a symbol of good luck. Its status is lofty. Its symbolic significance and cohesion are enormous and irreplaceable. Xilong didn't mean it. Its position and role in western culture is negligible. In a word, these two dragons have their own reasons and opinions. They have no relationship between origin and spread, which is different.
