Introduction to Jade Dew Cave: The Ming Dynasty writer Wang Shizhen said in his "Ling Cave Room" that "the four walls are covered with stone stalactites, as white as jade, dripping with sound, and falling like dew flakes, so it is called Jade Dew", hence the name. .
The entrance of Yulu Cave faces west. The cave hall is empty and the river valley is deep. The temperature is constant at 18℃ all year round, and it is warm in winter and cool in summer. The main cave is divided into two floors, bounded by the lower cave hall and the upper hall. There are several branch caves beside the hall, with a total area of about 8150 square meters.
