Introduction to Longjing Spring: There are four huge rocks blocking the stream bed in Longjing Spring. Two streams of clear water gush out from the cracks in the rocks. The hollow valley roars, which is spectacular. This round well located in the center of the boulder is the Longjing. The diameter of the well head is about 50 centimeters and the bottom of the well is unfathomable. It is said that it leads all the way to Tongpu. Legend has it that there was a severe drought one year in ancient times and there was a water shortage in Zhangyang Village, Taoshan Town. The water from the Longjing continued to flow more than 10 kilometers away, which solved the urgent needs of the villagers in Zhangyang Village. The people were all overjoyed and liked this well more and more.
