A long time ago, a pair of twin brothers came to Beishan. Cultivate one's morality in the mountains and collect medicines to treat diseases. One year, there was a drought in Jinhua, the mountain springs dried up, the land cracked, and the people were miserable.
In order to eliminate the suffering of the people, the two brothers meditated in the cave for 7749 nights, praying for the arrival of the gods, and taught themselves how to solve the drought. Their sincere hearts touched the world. Taiyi Xian Zhen came to the cave and attached it to the ears of the two brothers, saying, "Curling is a treasure, and it will turn into a dragon after drinking it."
Guided by the gods, the two brothers searched for curling in various caves in the mountain. That night, they came to a cave with torches, only to see strange rocks in the cave, one of which was as white as jade and shaped like an upside-down kettle.
From time to time, a drop or two of water dripped from the spout, and the brothers took turns to go up and pick it up with their mouths. This water is cold and sweet as dew, which is absolutely extraordinary. When they both drank dozens of drops, it was already late at night, so they fell asleep.
The next morning, the two brothers woke up and found themselves as two real dragons. Immediately flew out of the cave, and it rained cats and dogs over Jinhua. Since then, two real dragons have lived in the north of Jinhua, providing rain for the people. So people call the cave where dragons live "Shuanglong Cave", the cave where brothers drink water is called "Hu Bing Cave", and the cave where immortals give directions is called "Chaozhen Cave".
