How does Xuan Kongsanqiu like this book?

Kong Xuan's geomantic omen is very accurate, especially the geomantic omen of Yang Zhai. Although Kong Xuan's geomantic omen is famous, it is difficult to learn, because many books about Kong Xuan on the market are irrelevant and vague in theory, so we have to look for Kong Xuan's true classics from ancient books. In the field of geomantic omen in Kong Xuan, the most authoritative ancient books are White Subset, Xuan Ji Fu and Flying Fu. The contents of these three books are refined, which are interpreted by later generations. They are either ambiguous, off topic, or the language is difficult to understand. To this end, we invited Liang Weibin, a contemporary Feng Shui master, to personally write a vernacular interpretation, which not only combined these three books into one, but also explained them in vernacular as easily as possible, fearing that beginners could not understand them. Therefore, a chapter named "Feng Shui Theory" has been added in front, which aims to improve the readers' practical ability of Feng Shui and is also convenient. Therefore, this book can be divided into three parts: geomantic omen theory, ancient books theory and double star theory, and the ancient books theory focuses on three ancient books: Bai Zi's Tales, Xuan Ji's Fu and Fei Xing's Fu, so this book was named Three Essentials.
