Mythological creatures possessing some or most of the characteristics typically associated with dragons and serpents are common throughout the world`s cultures. Dragons and serpents are often held to have major spiritual significance in various religions and cultures around the world. Although dragons occur commonly in legends all over the world, different cultures have perceived them differently. Dragons in the Far East are generally seen as benevolent, whereas European dragons are usually malevolent. Korean dragon, Yong, is accepted widely as symbols of royal authority, good luck and sacred soul in the folklore and the oral literature, and is also many times worshipped. It is considered as mythical rulers of weather, especially controlling the rain and the water, and is usually depicted as the guardians of flaming pearls. The symbol and the significance of the dragon have influence on the existence of community as the main motives in the fields of divination by configuration of the ground and the Sea God rituals. Being an apotheosized dragon, the serpent was also the subject of worship as a false god and Koreans believed that allegorical serpents can achieve good and evil through the legends or the folktales. In Romania, three kind of dragons can be remarked. First, ``Balaur`` is very similar to the occidental dragons, with fins and multiple heads, in the second place, ``Zmeu`` (derived from the name of the Slavic dragon, zmey, zmiy etc.) is a humanoid figure that can fly and breathe fire, and in the last place, being a unique female, ``Scorpia`` has three hesds and belches fire too. The aspects and the characteristics of dragons and serpents existing in the Romanian oral literature are different with their recognized features accepted in the popular belief. There is not any different view that dragons are the target of the elimination as malevolent beings, but the former (in the case of the dragons in literature) depends upon the direct reason like the accession to the throne for the hero, the latter being motivated by indirect reasons such as the overcoming of many difficulties (as drought, calamity etc.). In the case of the serpents, ``serpents inside the house`` are commonly in the Romanian oral literature and the other side, ``serpents in the wood(or field)`` in the popular believes. Romanian ``serpent inside the house`` has great notion of deity of one`s family as the Korean serpent, Gureongyi. Like a literary material, the serpent varies according to the literary genre. For example, in the folktales appear the ``serpents inside the house`` which offer a feeling of intimacy, on the other side, in the ballads appear differently the ``serpents in the wood(or field)`` which have the negative image and cause a hostility. In these days, dragons and serpents maintain as ever the tradition of several thousands of years as a representative literary theme and material, especially in the fantastic literature. Dragons (and serpents) are very popular characters without interruption in the worldwide literature and they have acted as mediators between the West and the East and between the Past and the Future.
