I think the mysterious geomantic omen is the inherent law that geomantic omen can cross geomantic omen, which is very scientific. Shen Xuan's "Hong Kong Studies" is the source of metaphysical Feng Shui, so it is better to read Shen's "Metaphysical Feng Shui". Although this is a school of geomantic omen, it can be seen everywhere, but it is almost the same in the end.
QQ, a geomantic e-book from Shenkong and other places, was sent to your mailbox, please check it.
