Recently, I am more interested in architectural geomantic omen. Who can tell me what introductory materials I should read?

Architectural geomantic omen can be said to be a science without superstition, but it does have a certain cultural heritage. So I suggest reading some ancient books, such as Zhouyi and Laozi. If you want to see modern works directly, you can look at Feng Shui and some works by the famous Feng Shui expert Dong Bin. Introduce an electronic Feng Shui book, which is worth reading/forum/details 3712271_1.html.
