Introduction to Hukong Diyu: Hukong Diyu is located outside the east gate of the ancient city. It is a natural sea cave on the edge of the seaside and is a summer resort.
The so-called "Hu Kong" is a sea-eroded rock cave located at the edge of the water. There are large and small Hu Kong, with the big cave on the right and the small cave on the left, interconnected in the middle. A clear spring flows out, trickling out. The spring water is sweet and delicious, and it does not dry up during the drought. The spring water drips into the porcelain bowl in the sand, making a tinkling sound, just like dripping pearls and jade, so it is called "Drip Jade".
