The difference between the orientations mentioned in Feng Shui books and the geophysical orientations and the orientations when looking at the map

In Feng Shui, it has always been "south and south, north and south, left, east and right". In terms of geography, it is "up to the north and down to the south, left to the west and right to the east". In Feng Shui, "Heaven, South and Earth" are used to calculate directions and draw nine-square diagrams.

So, in fact, Feng Shui and geography refer to the same direction, but they have different explanations. There is no contradiction. Therefore, the south is the south of "the sky is south and the earth is north", and it is also the south of "the north is up and the south is down". The compass will always point to the edge, it will not change.

Also, the Xiantian Gua mainly refers to the body part to which the Bagua belongs, regardless of the direction it refers to. The Houtian Gua refers to the five elements and directions. Generally when looking at Feng Shui, we use the acquired hexagram to calculate.
