Introduction to Tianhe Dragon Palace: Tianhe Dragon Palace is located between high mountains. The Tianhe River in the cave circulates and flows endlessly, which can be called a miracle on earth. The cave is dotted with stalactites, and scenes such as carp leaping over the dragon gate, night of flowers and candles in the bridal chamber, the picture of Guanyin giving birth to a child, and the peach party in the Tiangong are lifelike.
