Why is the prevailing Yin-Yang Feng Shui and Xuan-Kong Feng Shui opposite?

1, it is too common for different schools to have opposite views on the same page.

2, the same genre, the same layout, the opposite view is also common, this should be related to personal level.

The advantage of crossing Yin and Yang is that you can't hold the compass and your mouth is straight. They have a relatively simple and broken formula, which is relatively rough, but most of them are in line with mainstream schools.

Of course, there are many other reasons, and different levels are the main problem.
