Mountain behind, water in front

The classic arrangement: high ground supporting the house from behind, water running before it. It is the plainest form of storing wind and gaining water — sheltered at the back, open in front so qi gathers. MYEONG actually tests for it and adds a bonus to the form score when a mountain is found opposite the facing direction and water on the facing side. It is not a residence-only rule — public buildings and shops sit by it too — so the bonus is the same for every space use. Without fine elevation data the test approximates by bearing rather than relative height, so a confidence level is reported alongside.
