How about the rare book "Six Benevolence and Three Books" in the Forbidden City?

Six People and Three Books is a rare book in the Forbidden City and a well-known classic I Ching. The Book of Changes and Shu Shu includes eight characters and four pillars, Daoism, Liu Ren, Liu Yi, Wei Zi, geomantic omen, plum blossom and so on. There are too many books, so I'll just say a few good Shu Shu books on Taoism, Liu Ren, Feng Shui and four pillars and eight characters for your reference.
