There is no Dragon King, just the legend of the Dragon King. The image of the dragon is the oldest ethnic symbol of the Yanhuang people. The legend about the dragon was originally more far-reaching than the recorded history. As a deity that appeared earlier and was recorded more frequently in ancient Chinese classics, the dragon’s basic function has always been reflected in that he is the one who brings clouds and rain, brings peace and prosperity. There is no doubt that thunder and lightning may be the phenomenological master of the clouds or floods. As history continues to advance, a rather disgraceful image has emerged from the orthodox bloodline of the dragon - the Dragon King. Although the Dragon King has completely inherited the basic functions of the dragon - to control the wind and rain and control the water veins, he has completely lost the sacred symbolic meaning of the dragon. Most images of dragon kings are either described as weak and useless, or as greedy and cruel. In short, there is no trace of the sacredness and glory of the dragon. The earliest appearance of the word "Dragon King" in ancient Chinese books can only be traced back to the Northern Wei Dynasty. Moreover, the records about the Dragon King at this time are all directly related to Buddhism. For example, there are two records in the "Luoyang Jia (sound: Qie) Lan Ji" of the Northern Wei Dynasty that mention the Dragon King. One of them says: At the beginning, when the Tathagata was transforming in the Wuchang country, the Dragon King was angry and caused a strong wind and rain, and the Buddha and monk Kali became damp inside and outside. When the rain stopped, the Buddha sat under a stone, facing east, drying his cassock. ... where the Buddha sits and where he hangs his clothes, there are also inscriptions on the pagoda. The Northern Wei Dynasty was an era when Buddhism was at its most prosperous. The Dragon King is portrayed here as a negative image who attempts to stir up troubles and prevent the Tathagata Buddha from transforming. This is actually to set off the fearlessness and transcendent spirit of the Tathagata Buddha. The Dragon King has a negative image when he appears. In the classics of later generations, Nuwa canonized nine dragon kings in one act, allowing them to travel to the lower world and nourish the creatures in the lower world. The nine dragon kings are: the five dragon kings of the five emperors, one and five, and the dragon kings of the four seas, one and four. However, the Dragon Kings we are familiar with are very timid. The third prince who had his dragon tendon pulled by Nezha, the Dragon King of the East China Sea who was snatched away by Sun Wukong for the Dinghai Needle, the Dragon King of Jinghe who was beheaded by Wei Zheng due to a rainfall error, the third prince of the Dragon King of the West Sea who carried Tang Monk on his back, and the Dragon King who played with dragons during New Years and holidays. . There is a folk legend about the legend of dragon playing. During the Warring States Period, Gui Guzi and Jinjiao Laolong met. Guiguzi said: "According to my calculations, it has rained recently. It is thirty-six o'clock in the city and forty-eight o'clock outside the city." Jinjiao Laolong deliberately let Guiguzi's The prediction failed, so he took advantage of his position to cause forty-eight o'clock rain inside the city and thirty-six o'clock outside the city. As a result, many people in the city died from the flood. Later, the Jade Emperor questioned him and the Golden Horned Old Dragon was demoted. In order to atone for his sins, Lao Long bowed to the people door to door to apologize to the people every year on the occasion of the New Year, and promised good weather for the year. Therefore, based on this legend, people made colorful dragons out of bamboo strips, iron wire, and silk gauze, and danced them every New Year to express joy and joy. It also meant that the old dragon surrendered and heaven followed people's wishes. In some areas, many legendary dragon kings appear in the image of a farmer who is honest, kind, diligent in helping others, responsive to requests, and also somewhat spiritual. There is a legend in Yanqing that the Black Dragon Lord of Yanqing is an old bachelor who earns a living by doing work for others. He is diligent and capable, and everyone is willing to hire him. But when hoeing the land, he would only leave one seedling in each of the four corners and in the middle. The shopkeeper got angry and said angrily: "Why are you so sparse? Leave one tree for me and it's all over?!" After hearing this, he really left one tree for me. The result is that it is rare, but in autumn there is really no shortage of food. After finishing his work, he left and disappeared when he reached the well. Later, people found his cloth shoes by the well and realized that he was a black dragon. He is a good man who helps everyone and does not offend anyone. Therefore, in the early morning, people come here to pray for rain from this old black man.
