Introduction to Jiulongpo: The legend of Jiulongpo began in the Tang Dynasty. It is said that nine evil dragons suddenly appeared at that time, which caused panic in people's hearts and made people unable to live in peace. All the people suffered. A few young and strong men joined together. He went to subdue the dragon, but all failed, and the people did not dare to disturb him. In order to ensure peace, all the annual grain and livestock were dedicated to it. Unexpectedly, Jiulong was not satisfied and continued to harm the people, killing their children, flooding, destroying their grain crops, and making the people miserable. One day, a man drank dew spring and claimed that he could subdue the evil dragon. The dragon subduer led all nine dragons into a mountain and brought them down with the blood-stained family sword. They did not kill them all. Jiulong was deeply influenced and turned them into stones to protect the world from harm.
