When measuring and setting polarity

The closer a facing is to the 277.5° or 292.5° boundary, the more easily a measuring error pushes it into You 酉 or Xu 戌. When a reading falls within 1° of either boundary, measure again at several points before setting polarity.

Once polarity is set, every room, door or item lying within the 277.5° – 292.5° sector, seen from the center of the house, belongs to Xin.

Questions about Xin

Is a house facing 285° a West-facing house?

Yes, but that is not precise enough. The West spans 45° (247.5° – 292.5°) and holds three mountains, Geng, You, Xin; a house facing 285° is in Xin. Naming the mountain tells apart houses only a few degrees from each other.

What does a house facing Xin sit on?

It sits Yi 乙, 97.5° – 112.5°. Sitting and facing are always exactly 180° apart.
