A long time ago, the Yellow River flooded and brought great disaster. Emperor Yao ordered Gun to cure the flood.
Nine years passed, but the flood is not receded yet. Gun failed. His son named Da Yu succeeded his father.
Da Yu was very smart, he figured out a way to divert the flood water into the sea. He took the people and personally went over the mountains to measure the terrain. Da Yu worked so hard that he did not even return home.
After thirteen years of treating the water, Da Yu finally made the Yellow River flow smoothly into the sea. From then on, the land on both sides of the Yellow River was fertile and people lived happily.
This spirit is a precious treasure of China.
