Tai Wu of Shang vs Yu the Great

Tai Wu appointed the virtuous minister Wu Xian, who helped restore moral governance. This appointment is credited with reviving the dynasty's fortunes after a period of decline, emphasizing meritocratic appointments.

Under Tai Wu's direction, the Shang court reinstituted proper ancestral rituals and moral codes. This reform reversed perceived decadence, restored divine favor, and led to a period of prosperity and stability lasting decades.

Tai Wu reigned for approximately 75 years, the longest of any Shang king. This extended period of stable rule allowed for the consolidation of Shang institutions and the peaceful transmission of power to his successors.

According to legend, Yu the Great devised a system of dredging and channeling to control the catastrophic flooding of the Yellow River. His success in flood control earned him the favor of the sage-king Shun, who later abdicated in his favor.

Yu the Great established the Xia dynasty, traditionally considered the first dynasty in Chinese history. He divided the realm into nine provinces and instituted a hereditary succession, breaking the previous system of abdication to the most capable.

Yu the Great ordered the casting of nine bronze tripod cauldrons, each symbolizing one of the nine provinces of China. These cauldrons became symbols of imperial authority and were passed down through successive dynasties.
