Yǎnshī
Yanshi lies east of Luoyang near the meeting of the Yi and Luo rivers. Its surroundings hold the remains of an early Shang walled city, while the rivers that nourished the region could also threaten the county town. A local gazetteer records a disastrous flood in 1343 and later inundations under the Ming. The county school, founded under the Yuan and rebuilt early in the Ming, was repeatedly repaired; after the Luo damaged it in 1761, officials obtained funds to restore it once more.
