Yang Zhai San Yao — Residential Spine

0) Positioning — what this page covers (and excludes)

Yang Zhai San Yao is the residential spine: site and arrange the Door (門/门), the Master (主), and the Stove (灶) after landform passes (Zang Shu) and before décor. You get selection sequence (lot → unit → interior), flow/use logic, evidence checks (noise, wind, drainage, smoke paths), and rules that survive modern utilities. Excludes décor “cures,” numerology cosplay, and time overlays used to excuse bad bowls. Form passes first.

1) What it actually asserts

• Door governs intake/exchange; it’s the house mouth. Bad doors bleed quiet, money, and privacy.
• Master anchors stability; master bedroom (the real decision-maker’s base) must be quiet, protected, and well-ventilated.
• Stove sets metabolic rhythm; manage heat/grease/exhaust; water and fire should cooperate, not clash.

If Door–Master–Stove are wrong, compass degrees won’t save you.

2) Origins & transmission — safe claims

• Yang Zhai = living dwellings (阳宅/陽宅), not graves (阴宅/陰宅).
• Three Essentials codified across Song–Ming–Qing: where people enter, sleep/decide, and cook inside sites that already pass landform tests.
• Relations: Zang Shu → storage physics; Qing Nang Jing → pattern inside form; Tianyu Jing → water–facing rules; this page trims to daily function.

3) Grammar — keep items separate

• Bowl: higher back, side embrace, bright hall, bounded mouth. No bowl = stop.
• Door: primary entry + approach geometry (stairs/drive/landing).
• Master: where the actual decision-maker sleeps.
• Stove: heat + grease + exhaust (cooktop/oven + hood + makeup air + drain).
• Water paths: streets/sidewalks/drains as micro-rivers; lift lobbies as eddies.
• Knives: T-junctions, corridors aimed at door/bed/stove, unbound mouths.

4) Field sequence — residential in five steps

1. Pick the bowl: calm back/side shields, usable bright hall, controllable mouth.
2. Choose building/unit by approach: prefer angled/offset entries; avoid head-on stairs/driveways.
3. Fix the Door first: if geometry/landscape can’t calm it, change unit.
4. Place the Master: quiet, protected volume; no corridor/road knives; clean ventilation.
5. Place the Stove: real exhaust + makeup air; avoid head-on sink clash; don’t aim flame at the main door.

5) The Door — intake without bleeding

What good looks like

• Approach slows before the door: landing/turn/alcove as micro bright hall.
• Offset sightlines from street/lift; no straight view into private zones.
• No wind tunnel: smoke/incense drifts gently, not straight through.

Red flags

• Head-on knife: corridor/road/stair aiming at the door.
• Flush geometry: door opens into a long fast corridor.
• Shared shaft blast: lifts/garbage vents near the door.

Fixes

• Angle the entry or add a screen/wing wall to break vectors.
• Widen landing with planters/bench for micro bright hall.
• Door seals & pressure balance for draft control.

6) The Master — stability where you actually sleep

What good looks like

• Two protected walls; no bed under big glass or on service shafts.
• No direct knives: corridor/doors pointing at the bed line.
• Ventilation & noise: openable window without fumes; low nighttime CO₂; tolerable ambient noise.

Red flags

• Shared wall with lifts/pumps.
• Window onto a knife road or exhaust alley.
• Room acting as hallway between spaces.

Fixes

• Swap rooms so the true master gets the protected volume.
• Add vestibule or turn the door to break bed knives.
• Acoustic sealing and filtered makeup air where needed.

7) The Stove — heat, grease, exhaust discipline

What good looks like

• Stable wall with ducted hood and makeup air (avoid negative pressure).
• Not facing sink head-on across a narrow aisle; prefer adjacent/offset.
• No direct sightline from main door to active flame/grease area.

Red flags

• Island cooktops with weak/shallow canopies.
• Hoods exhausting into shared shafts (blowback risk).
• Stove on a “knife” line sending heat/smell to bedrooms.

Fixes

• Wall the stove or upsize canopy depth/CFM; add makeup air.
• Offset sink (L-shape/jog) to stop clash.
• Partition/door closer so stove doesn’t “face” the main door.

8) Pattern refinement (after form passes)

• Use Qing Nang Jing to align door line with a generated sub-segment; avoid flushing the seat line.
• Touch 24 Mountains to avoid outflow through master/stove axes, not for decoration.
• Time schools (玄空/三元) are refinements—never rescues.

9) Apartments & urban realities

• Corridor = water: long straight corridors are flumes—favor offset entries.
• Elevator lobby = eddy: treat as micro bright hall; don’t face it directly.
• Mechanical stacks are wind/noise sources—keep master and stove off those walls.
• Parking ramps/loading bays are water mouths—don’t align your door with them.

10) Work, relationships, customers — why this matters

• Work: sane Door lowers stress; real Master room raises decision quality; stove discipline reduces maintenance.
• Relationships: offset sightlines, remove bedroom knives, and keep rooms from being hallways.
• Customers: home studios need door calm for steady client flow; kitchen discipline prevents complaints.

11) Micro-cases (abstracted)

A) Knife corridor entry

Door faces 20 m corridor. Remedy: flip swing, add wing wall + console to create an L; add inner screen. Result: quieter intake, fewer drafts.

B) Master on exhaust alley

Great view, bad fumes. Remedy: swap rooms; give master protected interior volume; view room becomes study. Result: sleep quality up.

C) Island stove smoke

Recirc hood spreads grease. Remedy: ducted canopy + makeup air; offset sink to stop clash. Result: cleaner air, fewer repairs.

12) Common traps — stop paying tuition

• Trying to “compass” out of a knifed door or noisy master.
• Placing stove where the architect left space, not where exhaust works.
• Rooms-as-hallways; beds crossed by traffic lines.
• Ignoring makeup air—strong hoods pull smells through bedrooms.
• One-season proof—inspect at night and during rain.

13) One-page checklist — Door • Master • Stove

• Door slows before entry (landing/turn)? Y/N
• Head-on knives at door removed/blocked? Y/N
• Master has two protected walls and low night noise? Y/N
• No corridor/door “knife” to the bed line? Y/N
• Stove has ducted hood + makeup air? Y/N
• Stove and sink not clashing head-on? Y/N
• No direct sightline from main door to stove flame? Y/N
• Bowl & mouth pass in wet + dry seasons? Y/N

Two “No” → change plan. Three “No” → change unit/site.

14) Ethics — proportion, records, safety

• Vent properly; seal gas lines; use GFCI where required; document changes.
• Don’t trade safety for symbolism.
• For people and money, custody of air, fire, and privacy beats ornament.

15) Closing

Yang Zhai San Yao is structural: Door decides how you meet the world, Master how you recover, Stove how you work and feed. Get these right inside a good bowl and most “mysteries” disappear.
