Approximately 1,500 years separated the Yangshao culture (5000-3000 BCE) from the Longshan culture (2500-2000 BCE) in ancient China.

The significance is that during the period of Yangshao societies changed from being relatively egalitarian to incipiently ranked. By the way, it is incorrect to refer to Yangshao as a 'dynasty'. Yangshao is a prehistoric neolithic culture that has a beginning and end. Dynasties refer to periods of reign of royal houses. There were no royal houses or state-level societies in Yangshao.

The Longshan culture developed after the Yangshao culture in China during the late Neolithic period, around 3000 to 2000 BCE. The Longshan culture is known for its advanced pottery techniques, including the use of potter's wheels and black pottery. They are also recognized for their highly stratified society and walled settlements.
