A long time ago, a huge flood hit ancient China. 

Emperor Yao was a leader during this time. He asked a man named Gun to stop the water. Gun tried to use magic soil called Xirang. He built dams and dikes to block the river. But the magic soil did not work. The water kept rising. 
Gun had a son named Yu. Yu tried a different way to help. Instead of blocking the water, he dug paths. These paths let the water flow away. Yu also had help from special beings. He worked with a dragon and a giant turtle.
The Great Flood of China is a famous story from ancient times. 

In the stories, the flood happened during the reign of Emperor Yao. The water filled the Yellow River and the Yangtze valleys. Yao wanted to find someone to stop the rising water. He asked his advisers, known as the Four Mountains, for help. They suggested a man named Gun to lead the work. Gun was a distant relative of the Emperor. He tried to stop the water by building dams and dikes. 
After Gun failed, a leader named Shun took over the work. Shun was also a relative of Emperor Yao. To prepare for the flood, Shun did many organized tasks. He changed the calendar so everyone could follow the same timing. He traveled to sacred mountains like Mount Tai to meet leaders. Shun also made sure everyone used the same weights and measures. This helped people work together on big engineering jobs. 
Some people believe this story comes from a real event. Scientists found evidence of a huge flood at Jishi Gorge. This happened on the Yellow River a long time ago. They date this event to about 1920 BCE. This is a few centuries after the traditional time of Emperor Yao. The real flood might have inspired the famous myth. It shows how a natural disaster can change a whole culture. 
Gun had a son named Yu who tried a new way.
The Great Flood of Gun-Yu is a foundational narrative in Chinese culture. 
Traditional accounts place the flood during the reign of Emperor Yao. The water flooded both the Yellow River and the Yangtze valleys. Yao sought a leader to manage the crisis and consulted the Four Mountains. This group of advisers recommended Gun, the Prince of Chong. Gun was a distant relative of Yao through the Yellow Emperor. Gun attempted to stop the water using a magical, self-expanding soil called Xirang. He stole this substance from the Supreme Divinity to build dams and dikes. 
Following Gun's failure, the leadership transitioned to Shun. Shun was another distant relative of Yao who lived in obscurity. Yao tested Shun through marriage and various environmental challenges before appointing him. Shun focused on organizational reforms to prepare for large-scale engineering. He reformed the calendar to synchronize timing across the empire. He also standardized weights and measures to facilitate coordinated labor. 

Gun's inability to control the flood led to political tension. He questioned the legitimacy of Shun's rule due to his modest background. Consequently, Shun banished Gun to Feather Mountain. The details of Gun's end vary in different accounts. Some sources say he died there, while others suggest he transformed into a dragon or a tortoise. This period of instability highlights the connection between natural disasters and social order. The struggle to manage the water became a struggle to manage a state.
Yu, the son of Gun, eventually took over the task of flood control.
Archaeological evidence suggests the myth may be rooted in a real event. Scientists identified an outburst flood at Jishi Gorge on the Yellow River. This event is dated to approximately 1920 BCE. This date is a few centuries after the traditional start of the Xia dynasty. The scale of this flood was comparable to other major global events in the last 10,000 years. This geological reality may have shaped the cultural response of the people living along the river. The disaster likely acted as a catalyst for complex social connections.
The legacy of the flood is found in the development of civilization. The efforts to control the water led to progress in land management and agriculture. It also improved beast control and societal well-being. The comprehensive approach to these problems helped establish the first dynastic state, the Xia dynasty.
