When measuring and setting polarity
The closer a facing is to the 142.5° or 157.5° boundary, the more easily a measuring error pushes it into Xun 巽 or Bing 丙. 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 142.5° – 157.5° sector, seen from the center of the house, belongs to Si.

Questions about Si
Is a house facing 150° a Southeast-facing house?
Yes, but that is not precise enough. The Southeast spans 45° (112.5° – 157.5°) and holds three mountains, Chen, Xun, Si; a house facing 150° is in Si. Naming the mountain tells apart houses only a few degrees from each other.
What does a house facing Si sit on?
It sits Hai 亥, 322.5° – 337.5°. Sitting and facing are always exactly 180° apart.
Whose birth-year mountain is Si?
It belongs to people born in a Si (Snake) year, counted from the Start of Spring rather than Lunar New Year. When the main door or an active, heavy item falls exactly in Si, say precisely whose Si birth-year mountain it touches.
