Yangshao painted pottery originated from the west, with connections with Anau in Central Asia and Tripolje in Eastern Europe. Heavily flawed, this view has been long abandoned in academia. The Longshan culture period is an important period in history. The use of bronze ware, the emergence of a large number of city sites, and the wide application of thin-bodied black pottery and quick-wheel pottery-making techniques indicate that the social productive forces achieved unprecedented development during this period, which led to the polarization of the rich and the poor within the society; thus the emergence of class antagonisms. The Longshan culture had individuals of extraordinary stature who have been dubbed the "Longshan giants". Some samples of Longshan culture males recovered from Shandong fell between the 180 cm to 190 cm height range, making them taller than any other Neolithic population in the world. Modern day inhabitants of Shandong have the tallest heights of any Chinese province. The tallest Longshan individual discovered so far is a 193 cm male, aged approximately 16-18 years old, from Shaanxi.
