Introduction to Yuwangchi: When you walk into the Xishan Scenic Area, the first thing you see is Yuwangchi. It is located under the cliff on the right side of the stone embankment. It is 8.2 meters long and 6.6 meters wide. There is a clear spring in the pool, green grass and spring water. The temperature remains between 25 and 6 degrees all year round. There is a water outlet in the east of the pool, carved with a stone toad, known as "Toad Mouth". There is a stalagmite in the middle of the spring pool, 2.6 meters high. Legend has it that it was the tool used by Dayu to control the water and open the dragon gate.
