By comparing viewpoints, we can see that the pools were located outside the ramparts, but on the highest esplanade, there's a second esplanade, and beyond that, we reach the terraces where the houses and rice paddies are located. The pools with water lilies on the rampart side may be connected to the outer pool without water lilies, which is actually quite nice along the esplanade before ending up in the rice paddies; it's therefore an artificial waterfall. I will continue to gather different viewpoints and make this type of comparison in order to create a map of the city of Fang.
