What is the basis of the first year of Daoli?

The Yellow Emperor was worried about his aging in his later years. Later, he learned from a conversation with Qiu Fu Palace: "Everything in the world has a cycle of life and death, and only immortals can live forever." So I had the idea of pursuing immortality. He heard that there lived a fairy Guangchengzi who was over 200 years old/kloc-0 in Kongtong Mountain, so he went to ask him. Hiroko told him to keep his heart calm, be quiet and keep practicing, so that he can shine with the sun and the moon and coexist with heaven and earth. The Yellow Emperor was greatly inspired by Guang Chengzi's words, and since then he has studied Taoism with Guang Chengzi. Later, an alchemist was needed to save the people. After the casting was completed, Huanglong descended from the sky and welcomed the Yellow Emperor to heaven.

I think this has something to do with it.
