Introduction to Splitting Stones with Knife: During the reign of Emperor Xuanzong of the Tang Dynasty, it is said that a villager was bitten by a poisonous snake at Yuxian Pavilion. In order to save the person, Wang Xian (Wang Xi) crossed mountains, water, and rocks and split them with a knife. The rocks were split during the rescue. Two pieces fell to the stream and a few remained on the roadside.
