Introduction to the Fairy Bath: The "Fairy Bath" is nearly 3 meters long, 1 meter wide and half a meter deep, shaped like a large bathtub. Although it is located at the top of Yucang Mountain, which is more than 900 meters above sea level, and has no water source, the pool is filled with clear water all year round. It never runs dry in midsummer and does not overflow even after continuous rainfall. The water in the pool is warm in winter and cool in summer, which is very strange.
