Since ancient times, there has been a difference between immortals and mortals. Mortals, who eat grains and grains on the outside and have seven emotions and six desires on the inside, will suffer from birth, old age, sickness and death; immortals, drink the essence of nectar, control the soul of the emperor, and cultivate the body of heaven and qi. Although there is a world of difference between immortals and mortals, they are not intranslatable from each other. If a mortal devotes himself to cultivation and only thinks about the things of the world in his heart, and when he goes to the physical body, he will eventually attain the Tao. If the immortals are relaxed and slack, their hearts are full of mundane**, although they can still live forever, they have lost their spirituality.

At the beginning of Nuwa's creation, she imitated her own body and made it by herself, and the clay figurines she made were all spiritual. Among them, there is a clay figure that is beautiful and amazing, and the spiritual power is abundant, and it is quite similar to Nuwa, so Nuwa likes it very much. This clay figure is also often extraordinary, rarely in the company of others, but likes to accompany Nuwa. After a long time, Nuwa noticed that her temperament was very strong and she had a pure heart, so she gave the Tianchi Holy Palace as her cultivation place, and agreed with her that she would not leave the palace unless she could reach heaven and earth.

The Holy Palace is located on the bank of the Tianchi in Changbai Mountain, and it is the place where the purest qi gathers. It is made of palm-sized square white jade, which is angular, uniform and flawless, and closed with a fist-sized round red jade that is wrapped around a series of beams to form a roof, which is warm and transparent, equal in color and red as blood. The holy palace is separated from the inside by water as a door, and the water that is the door is the purest water in the world, and no one who is made of the door is allowed to enter unless it is the purest of the people. The body of the Holy Palace is protected by divine power, and even if the outside world collapses and cracks, the inside of the Holy Palace is as stable as a rock.

A group of southward geese lost their way and accidentally flew past the Changbai Pond. The head goose saw through the red jade that there was a woman in the holy palace who was abnormally beautiful, and for a moment she forgot to flapp her wings and lost her motivation and fell straight down. The geese behind him also fell with it and disappeared into the col, leaving only a series of wailing sounds. This scene happened to be bumped into by the clay man of the Holy Palace, and he couldn't help but laugh dumbly, and since then he has called himself a falling goose.
