Xūyí

Xūyí stands near the lower Huái River, where low hills overlook the waters of Hóngzé Lake. Across the river lay the old city of Sìzhōu and the ancestral tombs of the Míng imperial family. Work on the tombs began in 1385, but in 1680 floods on the Yellow and Huái rivers submerged both the city and the burial site.
