Does the geomantic "orientation" of Sanhe Yin House refer to the headrest orientation or pedal orientation of the buried person?

Pedal direction

The orientation of the cemetery does not depend on the zodiac, nor is it suitable for any zodiac.

That is, when you choose the geomantic omen of the Yin House, you can decide whether you can stand upright according to the layout of the environment.

What direction to set depends on the compass. This direction must be prosperous for future generations.

Of course, this needs to be combined with daily burial, and it can't be explained clearly at once.
