In ancient times, the world was still in chaos. So, the Supreme Master Pangu split the heaven and the earth with his axe, and from then on, there was a boundary in the world. The heavenly fairy Nuwa sprinkled her blood into the earth, and there were creatures in the world. The Supreme Lord Pangu transformed himself into the yang and sun, and the heavenly fairy Nuwa transformed herself into the yin and moon. Then day and night intertwined in the world, and the four seasons changed. In order to prevent the world from falling into chaos again, the Supreme Lord Pangu scattered his 12 spirit beads to the earth. When the spirit beads are reunited, the world can restart a new reincarnation.
