Zhěhóng
Zhehong lies north of Guangnan amid the mountains approaching the Guangxi frontier. In Qing times it was a military post, garrisoned by an officer charged with watching this northern approach. The Guangnan gazetteer records the chain of smaller posts leading from the prefectural town toward Zhehong, a reminder that communication across the hills depended on a succession of maintained stations. The post was one point in a wider network joining the seat of government with the frontier country.
