What you said seems to be three yards.

Yin and Yang Feng Shui: Yin House Feng Shui (the villa where the dead live) and Yang House Feng Shui (the place where the living live).

Fortune-telling: the application content of Yijing

Master of Yin and Yang: a mage or a man of God, who is in contact with the underworld (ghosts, gods, spirits, buddhas and Taoists) and communicates with the world (human beings).
