Introduction to Qixingtan: Qixingtan is located at the top of Jiulong Waterfall, 12 meters long, 8 meters wide and 4 meters deep. There are 10 glacial mortars with a diameter of about 0.5 meters beside the pool, forming the Danjing Group. 7 of them are arranged in a shape like the Big Dipper, hence the name Qixingtan. After passing Qixingtan, there is a strange stone, 3 meters high and 6 meters long, shaped like a boat, with a cypress, a pine and a rhododendron naturally growing on it, which is called the Dragon Boat Stone.
