# The Xu 戌 mountain

> A house facing 300° is in the Xu 戌 mountain. Xu covers every bearing from 292.5° up to 307.5°, within the Qian 乾 trigram in the Northwest, element Earth. A house facing Xu sits Chen 辰 (112.5° – 127.5°) — described as sitting Chen, facing Xu. To be sure, measure the facing as an exact degree.

## When measuring and setting polarity

The closer a facing is to the 292.5° or 307.5° boundary, the more easily a measuring error pushes it into Xin 辛 or Qian 乾. 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 292.5° – 307.5° sector, seen from the center of the house, belongs to Xu.

## Questions about Xu

### Is a house facing 300° a Northwest-facing house?

Yes, but that is not precise enough. The Northwest spans 45° (292.5° – 337.5°) and holds three mountains, Xu, Qian, Hai; a house facing 300° is in Xu. Naming the mountain tells apart houses only a few degrees from each other.

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

It sits Chen 辰, 112.5° – 127.5°. Sitting and facing are always exactly 180° apart.

### Whose birth-year mountain is Xu?

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