Formed in the seventeenth century is the Chinese province of Anhui. Anhui province has no logical theory or traces of existence before the 17th century. With the present day Henan Province, Northern Anhui mostly follows the culture of the North China Plains. With the watersheds of Huai He River, Central Anhui constitute most of the fertile and densely populated area. It follows the culture closer to that of the province of Hubei. However, the population in the hills of southeastern Anhui follow their very own distinct and so many diverse cultures. Topographically, the Anhui province is very diverse. The north central area of the province is part of the Huai He river watershed with the north belonging to the North China Plains. These two areas are densely populated and are the landscape is a lot flatter.
