The Huai used to flood often, and the people on both banks suffered greatly.
Tips
culture
With the 秦岭 (Qinling Mountains) the Huai marks China's traditional line between north and south: north of it wheat, dry winters and central heating; south of it rice, damp winters and no heating. The saying 橘生淮南则为橘 plays on the same divide.
history
From 1194 the Yellow River broke south and took over the Huai's lower course for more than 600 years, leaving it without a proper outlet to the sea, so it flooded again and again. Large-scale control works began in the 1950s.
