The sky and earth are dark and yellow, and the five elements open the way, turning cocoons into butterflies. There has been a legend among the people for thousands of years that when Xuanhuang comes out, his fortune will be reversed. Xuanhuang has been hiding in the market anonymously for generations, and no one knows who they are. I only know that Xuanhuang can turn cocoons into butterflies, and the stars will change in time.
