In the core area of Wudang Mountain, there is a hidden passage connecting the Wulong Palace and the Nan Yan Palace. As there are three ancient rock temples standing one after another on it, it is called the "Three Yuan" Ancient Path.

In his "Seven Characters", the Tang Dynasty poet Lu Yan expressed his feelings about the operation of heaven and earth and the growth of all things by using the lines "When the celestial principles rotate, the three elements are pure; when the earth veins are unobstructed, all things come into being" ‌. The Dashi Rock is shaped like a huge mansion. Inside the hall, the true warriors are dressed in splendid crowns and splendid robes, and the roof is adorned with a riot of colors of glazed tiles. The stone chi head is carved as if alive, and the dripping water has never ceased for a thousand years. Zhongyuan Rock stands alone, while Xiayuan Rock features a nine-story lofty platform and entwined peonies that are exquisitely crafted.

The name "SAN Yuan" originated from the ancient Chinese people's natural worship of heaven, earth and water. The Upper Yuan Celestial Official, the Middle Yuan Earthly Official, and the Lower Yuan Water Official represent the ultimate interpretation of Taoism's reverence for the natural world and the harmony of the universe.

The "SAN Yuan Ancient Road" in Wudang is not only a witness to history but also a fusion of Taoist culture and natural forces. It seems like a time tunnel, guiding us to explore the wisdom and beliefs of the ancients and listen to the echoes of history.
