How do I know the secret of Yijing Feng Shui?

First of all, the Book of Changes is the Book of Changes. From ancient times to now, it is divided into five techniques: mountain, medicine, life, physiognomy and divination. Feng shui belongs to the category of physiognomy. As for distinguishing authenticity, hehe is really not necessarily a fake book. Next, I suggest you look at the skill categories of SikuQuanShu. Relatively more reliable. As for many books of the Book of Changes now, it seems that there are also many translations.
