Known as the "Pearl of Jinling", also known as Houhu and Beihu.
The reason why Xuanwu Lake got its name:
There is a Xuanwu Lake in Nanjing, which was originally called "Houhu" or "Beihu" because Xuanwu Lake is in the back or north relative to Taicheng. Corresponding to the "Northern Xuanwu" in Feng Shui, Xuanwu District is named after Xuanwu Lake.
