# The Mao 卯 mountain

> A house facing 90° is in the Mao 卯 mountain. Mao covers every bearing from 82.5° up to 97.5°, within the Zhen 震 trigram in the East, element Wood. A house facing Mao sits You 酉 (262.5° – 277.5°) — described as sitting You, facing Mao. To be sure, measure the facing as an exact degree.

## When measuring and setting polarity

The closer a facing is to the 82.5° or 97.5° boundary, the more easily a measuring error pushes it into Jia 甲 or Yi 乙. 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 82.5° – 97.5° sector, seen from the center of the house, belongs to Mao.

## Questions about Mao

### Is a house facing 90° a East-facing house?

Yes, but that is not precise enough. The East spans 45° (67.5° – 112.5°) and holds three mountains, Jia, Mao, Yi; a house facing 90° is in Mao. Naming the mountain tells apart houses only a few degrees from each other.

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

It sits You 酉, 262.5° – 277.5°. Sitting and facing are always exactly 180° apart.

### Whose birth-year mountain is Mao?

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