For people like me who like to take trains, this trip to Yixing has made a lot of strategies. The nearest to the charity is Zhangzhu Town, where I stayed at the hotel the night before, and the first group of tourists entered the scenic area early the next day. I changed 228 to 202. I took the first bus at 7:40 in Zhuling, which actually arrived ahead of schedule. The driver was also an interesting person. He said let me count to 300. After getting off the bus, we went straight to the tourist center to change the net ticket. I don't know if it was lucky or should be. We didn't invite a tour guide, but there was a free tour guide at the entrance of the cave to explain to us. Shanjuan Cave is a famous limestone karst cave. The whole hole is composed of four holes, which are singular and interlinked. The most curious are the caves and water caves. The water tunnel is more than 100 meters long. It enters the cave like an underground palace. The whole tour is still enjoyable!
