Nánxī
Nanxi stands on the Yangtze downstream from Yibin, its old town enclosed by walls above the river. The county seat moved here in the tenth century, and the walls were repaired in the Ming after earlier defences had fallen into disrepair. The Wenming Gate, begun in the Zhengde reign, was rebuilt in 1764 under the Qing. Its gate tower watched over the streets within and the river traffic beyond.
