Story goes that long long ago, the sky and earth were integrated into one body that like an egg. The whole universe was inside a shell so it was dark and quiet. Then Pengu, who was born to set about the task of creating the world, finally woke up after his long nap. When he found the universe was too small for him, he picked up an axe and broke the shell. The sky and earth were separated from each other after his swing of axe. Afraid that the two get together again, Pangu stood between them and pushed up the sky.

However, the whole task took 18,000 years. During all these days, Pangu grew ten feet a day and the distance between the sky and earth increased each day. After 18,000 years, Pangu exhausted and went back to sleep but never wake up again.

It is said that his left eye became the sun and his right eye became the moon; his trunk became high mountains and his blood became rivers; his muscle became the soil field; his hair and beard became the stars and grasses; his teeth and bones turned out to be precious stones and minerals; his breath became the wind and cloud; his shout became the thunderbolt; his sweat turned out to be the rain. The parasites on his body then became the divers races of humankind.
