What was the impact of China’s geography on the development of Chinese societies?

TThe term China, like the term India, does not refer to the same geographical entity at all points in history. The historical China, also called China proper, was smaller than present-day China. The contemporary People’s Republic of China includes Tibet, Inner Mongolia, Turkestan, Manchuria, and other territories that in premodern times were neither inhabited by Chinese nor ruled directly by Chinese states.

Neolithic Jade PlaqueThis small plaque (2½ inches by 3¼ inches), dating from about 2000 B.C.E., is similar to others of the Liangzhu area near modern Shanghai. It is incised to depict a human figure that merges into a monster mask. The lower part could be interpreted as his arms and legs but at the same time resembles a monster mask with bulging eyes, prominent nostrils, and a large mouth.
