If you are asked to name some national emblems of China, the dragon will probably be one of the famous images that pop into your head. We Chinese often consider ourselves "the descendants（后代）of the dragon." It is not unfamiliar to you that your parents hope that you "may become the dragon".  

　　As a mythical（神秘的）creature, the dragon is deeply rooted in Chinese culture. Traditionally, dragons are considered to govern rainfall. They have the power to decide where and when the rain falls. In addition, the dragon is a symbol of imperial （帝王的）power. The emperors thought they were real dragons and the sons of the heaven.  　

But the creature is regarded differently in Western countries. In the Bible, dragons represent the devil（恶人）. Western people usually see dragons as cold-blooded reptiles（爬虫）, like snakes and cruel killers. In their eyes, dragons are also dishonest.　　

　　Dragons in Western literature are presented as monsters（怪物）. It is a common tale for a mediaeval knight（中世纪的骑士） to kill a dragon and save a princess and her country from its evil. Even the popular boy wizard Harry Potter has to battle against a dragon.  　　

　　However, dragons are not all bad in the West. "Puff the Magic Dragon" is a well-known song. The lyrics(歌词) tell a bitter-sweet story of the dragon Puff and his playmate Jackie Paper, a little boy. When Jackie grows up, he loses interest in the imaginary adventures of childhood and leaves Puff upset. Puff represents the innocence of a child's imagination, which is very positive for a dragon.
