The Ancient Chinese Dynasty was composed of four dynasties: the CHI, HAN, QIN, and CHOU. The CHI dynasty was the first dynasty in Chinese history, lasting from 2205 to 1766 BC. The HAN dynasty followed, lasting from 206 BC to 220 AD. The QIN dynasty was the shortest of the four, lasting from 221 to 207 BC. Finally, the CHOU dynasty lasted from 1027 to 256 BC. These four dynasties are considered the most influential in Chinese history, as they laid the foundation for many aspects of Chinese culture.
