# The Ding 丁 mountain

> A house facing 195° is in the Ding 丁 mountain. Ding covers every bearing from 187.5° up to 202.5°, within the Li 离 trigram in the South, element Fire. A house facing Ding sits Gui 癸 (7.5° – 22.5°) — described as sitting Gui, facing Ding. To be sure, measure the facing as an exact degree.

## When measuring and setting polarity

The closer a facing is to the 187.5° or 202.5° boundary, the more easily a measuring error pushes it into Wu 午 or Wei 未. 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 187.5° – 202.5° sector, seen from the center of the house, belongs to Ding.

## Questions about Ding

### Is a house facing 195° a South-facing house?

Yes, but that is not precise enough. The South spans 45° (157.5° – 202.5°) and holds three mountains, Bing, Wu, Ding; a house facing 195° is in Ding. Naming the mountain tells apart houses only a few degrees from each other.

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

It sits Gui 癸, 7.5° – 22.5°. Sitting and facing are always exactly 180° apart.
