In the south of Chu, there are those who are underworld, who consider five hundred years old as spring and five hundred years old as autumn; in ancient times, there were those who were called Dachun, who consider eight thousand years old as spring and eight thousand years old as autumn. At the beginning of the earth, everything was still as it was at the beginning, and we met in this rolling world of mortals. Who has become whose obsession, who has fallen into whose nightmare. Perhaps, when the sky was full of yellow sand, when our roots were still firmly rooted in the supreme world, I became accustomed to your existence. From the moment we met, I knew that you would be the fate that I could not escape in my life, so why not use my origin to name you and make this entanglement deeper?
