The Middle-Lower Yangtze Plain
From Wiki China org cn
Stretching eastward from the Wushan Mountain to the coast, the plain was formed of alluvial deposits from the Yangtze River and its tributaries. With an average elevation of lower than 50 meters and part of it lying below 5 meters above sea level, it is generally lower than the North China Plain. Crisscrossed by many rivers and dotted with lakes, it is known as "a swampy region."
