Sìhuì
Sihui lies on the Sui River, which flows southeast through the hills toward the Bei River. Its old county town was enclosed by a wooden palisade in 1390. Between 1464 and 1467 the Ming replaced it with brick walls and four gates, with a moat outside. Within stood the county offices and a Confucian school founded under the Song. In 1782 the magistrate established the Suijiang Academy beside the school, adding another place of learning to the old town.
