Introduction to Jiu Nu Spring: After the cruise ship departs from the Black Tiger Spring Station, it goes westward along the moat. On the banks of the river are the famous Jiu Nu Spring, Agate Spring and Baishi Spring. The spring water here is about two meters deep, and it is also the place with the best water quality in the entire landscape belt. They gush out one after another, forming a rippling inlet, which is very beautiful.
