Nu Wa witnessed such a strange disaster and felt very painful, so she decided to mend the sky to end it. She chose various colored stones, set them on fire and melted them into mud, filled the hole with this mud, and then cut off four feet of a chinemys reevesii as four pillars to support half the collapsed sky. Nu Wa also captured and killed the black dragon, which killed the people, and stopped the arrogance of the dragon and snake. Finally, in order to prevent flooding, Nuwa also collected a large number of reeds, burned them into ashes and buried them in the flood that spread everywhere.
After some efforts and rectification by Nu Wa, the sky was finally filled up, the land was filled up, the water stopped, the dragons, snakes and beasts disappeared, and the people lived a happy life again. But after all, this catastrophic disaster left its mark. Since then, the sky is still tilted to the northwest, so the sun, moon and stars naturally return to the west, and because the ground is tilted to the southeast, all the rivers gather there. When the rainbow appears in the sky, it is the colorful light of our great Nuwa.
