Baogong Lake is the inner lake of Kaifeng City, Henan Province. It is located in the ancient wall of the Song Dynasty and is in the southwest corner of the ancient city. The entire lake appears northwest-southeast, like a reclining gourd. The buildings around the lake are full of features, and the lake is clear and transparent. Although it is located in the Central Plains, it has the style of Jiangnan Water Village. On the summer evening, the road along the lake is a good place for citizens to take a cool walk.
