Does Xinxing County Xinhua Bookstore have Tianxin Zhengyun Selected Day books to buy?

Yes.

Although the ancient Feng Shui books explain the theory more thoroughly and are a must-read for in-depth study of Feng Shui, the ancient and modern methods of Feng Shui have changed greatly. Without a certain foundation, it will lead to confusion. Shape method is an important part of Feng Shui, and any school attaches great importance to it. But it is a pity that good books on form and method are rare nowadays, at least I haven't seen them yet. In terms of regulating qi, Sanhe, Xuankong, Bazhai, etc. are more common. If you are just getting started, you can start with a few books on Xuan Kong Feng Shui. Although there are still some contents in the book that can be discussed, the good news is that the language is plain and the entries are clear.
