It stores 42 million cubic meters with 3.3 square kilometers waters. In the lake, the capes stand; ripples are flashing, and the view is extremely beautiful. In the north of the lake, there is a mountain called Maoping Mountain, at the north of which there is grave of Wu fuzhi, a famous traditional Chinese painter. In the south of the lake, there stands Siquan Mountain with the old saying that it is a good place for graves because it has gold, wood, fire and earth, at the foot of which the scholar Wu Zhifang in the Song Dynasty and his son Wu Lai were born in the Wu Xi Village. The two mountains are the prefect places for enjoying the sight of the lake.
