Besides, you turned the gossip upside down. Ancient divination and numerology, such as Luo Shu, Qimen, Liu Yi, Da Liu Ren and Yijing, have always used acquired gossip. So gossip comes first, and innate gossip comes last. As for the eight characters formed after the Song Dynasty, there is no need to gossip at all. Innate gossip was introduced by later generations around the Song Dynasty according to the Book of Changes, in which "heaven and earth are positioned, thunder and wind are thin, mountains and rivers are ventilated, and water and fire are incompatible". Therefore, it has not been fully recognized in academic circles (mainly because of the position dispute). It first appeared in Mei Hua Yi Shu in the Song Dynasty, but in Huang's Ji Jing's, only the hexagram sequence was used. In other words, you only need to exchange 1, 2, 3, 4, 5, 6, 7 and 8 for earthquake-stricken areas respectively. All fortune tellers use gossip. I want to know why you study this. If you want to learn fortune telling, you don't need to read the Book of Changes. Learning heavenly stems and earthly branches, Five Elements, Eight Diagrams and Orthodox Fortune Telling is basically enough.
