Ancient meteorites pierced mountains and valleys, falling into this cave. Meteorites are shaped like ingots, shining brightly on moonlit nights, and mountain people come to worship them one after another. During the Later Tang Dynasty, Changsun Wuji was exiled here and built a temple to worship his ancestors, sending his thoughts to Chang'an. However, he was feared by Empress Wu Zetian and was given the honor of hanging himself here.
