The early Chinese civilization flourished along the Yellow River valley around 5000 years ago. Natural barriers isolated China, fostering a strong sense of national identity. The first dynasty was the Xia, established by Yu who implemented flood control projects. The subsequent Shang dynasty gained control of the region through organized bureaucracy and military might. They developed advanced agriculture, handicrafts like silk, and the first form of writing in China. Despite social stratification, family and respect for elders were core values. The Shang fell when nomadic groups like the Zhou allied and overthrew the corrupt rulers.
