# The Yin 寅 mountain

> A house facing 60° is in the Yin 寅 mountain. Yin covers every bearing from 52.5° up to 67.5°, within the Gen 艮 trigram in the Northeast, element Wood. A house facing Yin sits Shen 申 (232.5° – 247.5°) — described as sitting Shen, facing Yin. To be sure, measure the facing as an exact degree.

## When measuring and setting polarity

The closer a facing is to the 52.5° or 67.5° boundary, the more easily a measuring error pushes it into Gen 艮 or Jia 甲. 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 52.5° – 67.5° sector, seen from the center of the house, belongs to Yin.

## Questions about Yin

### Is a house facing 60° a Northeast-facing house?

Yes, but that is not precise enough. The Northeast spans 45° (22.5° – 67.5°) and holds three mountains, Chou, Gen, Yin; a house facing 60° is in Yin. Naming the mountain tells apart houses only a few degrees from each other.

### What does a house facing Yin sit on?

It sits Shen 申, 232.5° – 247.5°. Sitting and facing are always exactly 180° apart.

### Whose birth-year mountain is Yin?

It belongs to people born in a Yin (Tiger) year, counted from the Start of Spring rather than Lunar New Year. When the main door or an active, heavy item falls exactly in Yin, say precisely whose Yin birth-year mountain it touches.
