From very early on the Si River was connected with the Huai and Yangtze Rivers as well as the Central Plain of China for a long period in its history.  In 1194, at the time of the Song and Jin Dynasties, the Yellow River altered its course southwards, engulfing the lower reaches of the Si River below Xuzhou City and those of the Huai River below Huai’an City.

However, due to the large amount of silt carried by the river, it left behind a 4 to high layer of mud in the lower reaches of the Si River’s former course.
