How to get started in separating water from air? What e-books or materials can I learn online?

First of all, you should have some basic knowledge. Ke Sheng's five elements, heavenly stems and earthly branches, gossip and their positions and representatives are things, as well as the book of Hutuluo, knowing the compass, these are the most basic. Then I read a book. In fact, Kong Xuan Feng Shui is a combination of Liu 'antou and Li Qi, and I mainly study Li Qi, so I need to know something about Liu 'antou. My first contact with geomantic omen was from Jinsuo Yuguan, then Bazhai, and then Kong Xuan. Kong Xuan is mainly used by nine planets. Through the entry of Yuanjiu, Yunxing, Nianxing and Yuexing in different periods, the nine planets were spread according to the difference of mountains and stars. It is not static, so the verification rate is high. If you don't have a master belt, you can also read the introduction of the book. When you accumulate more, you can naturally communicate with other feng shui masters. I recommend several books to you, including The First Book of Feng Shui, Illustrated Feng Shui of Song Dynasty, Feng Shui of Hu, and Impermanent Feng Shui Lecture, Illustration of residential feng shui, Feng Shui of Folk Houses, Full Notebook Edition of Yang Zhai Lecture, Introduction to Yang Zhai Inference, and Feng Shui Correspondence Textbook. A complete collection of home feng shui, research and application of feng shui, etc. And the compass are completely understood. These online books include e-books, such as the first book on Feng Shui, which explains the metaphysics of Song and Hu. It's best to buy a physical book, because the pictures in the e-book are incomplete or not. When you understand these books, you will get started, and then you will have to buy a genuine collection of Song Metaphysics as a classic and teaching material to read. I don't have to tell you what to read for another promotion, because you already know. I hope it helps you.
