What is the specific meaning of the "fold" of the nine planets in Feng Shui?

That's because of the number of yin and yang in Luo Shu. Luo Shu's law is: wearing nine shoes, one on the left, three on the right, seven on two shoulders, six on eight is enough. That is, the sum of the number of yin and yang corresponding to each divination position is ten. The river map is the mother of gossip, and Luo Shu is the source of qi. Therefore, academically, it is believed that the nine planets can be folded according to the Luo Shu to correspond to the nine planets.
