The red phoenix is one of the stars in the purple bucket. Fu's disciple turned out to be a disciple of Nuwa. Because Nu Wa was soaring, there was no way to cultivate Hongluan, so Nu Wa entrusted Hongluan to the government and became his big disciple.
"Red Luan moves the stars" is calculated by some ancient magicians according to astrology and numerology, and it is a kind of divination in astrology.
Classical numerology insists that the wedding date can be counted, which is inferred from two modes. First, when Hongluan, Tianxi or Tianyao and Xianchi meet the limit of time or life, they are commonly known as Hongluan stars; Second, Lu Guangyao's entry into the husband-and-wife palace will enhance his strength and there must be an incentive to get married.
Hongluan is only a small part of the eight characters, and it can't fully represent people's fate.
