# The Qian 乾 mountain

> A house facing 315° is in the Qian 乾 mountain. Qian covers every bearing from 307.5° up to 322.5°, within the Qian 乾 trigram in the Northwest, element Metal. A house facing Qian sits Xun 巽 (127.5° – 142.5°) — described as sitting Xun, facing Qian. To be sure, measure the facing as an exact degree.

## When measuring and setting polarity

The closer a facing is to the 307.5° or 322.5° boundary, the more easily a measuring error pushes it into Xu 戌 or Hai 亥. 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 307.5° – 322.5° sector, seen from the center of the house, belongs to Qian.

## Questions about Qian

### Is a house facing 315° 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 315° is in Qian. Naming the mountain tells apart houses only a few degrees from each other.

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

It sits Xun 巽, 127.5° – 142.5°. Sitting and facing are always exactly 180° apart.
