Is it true that the tutorial "Tips for Geomantic Layout of Yijing" circulated on the Internet? Is it a scam? Why is the market not for sale? Why is it only sold online?

I suggest you not buy it. I feel that everything I'm looking for online has just been sorted out. Many do not conform to the five elements of feng shui. For example, what is the introduction? See red, see pictures, see. . . This statement is completely copied from another book circulated on the Internet by the Eight Academies. Moreover, it is conditional to have these three views. If divination is inconsistent, it is not suitable for entry.

I think this book is extremely misleading.

If you really want to learn Feng Shui, learn it solidly. If you really want to adjust Feng Shui at home, find someone who really understands Feng Shui.
