Kinh kham dư dương trạch: nhà ở là then chốt âm dương và khuôn mẫu nhân luân; người nhờ nhà mà an, nhà nhờ người mà tồn. Bàn hướng–vị, âm trạch/dương trạch, thiện ác họa phúc theo bố cục chỗ ở. Là nguồn quan trọng của thuật chọn nhà, khác hệ âm trạch (mộ địa) của Táng Thư.
Ứng dụng: Dương trạch phong thủy, chọn hướng lập cư, kham dư thực hành.
《黄帝宅经》（《宅经》）是现存最早专论阳宅（及旁通阴宅）的形法经典，假托黄帝而实出唐以前方技之流，收入《道藏》与《四库》。核心义理以阴阳为枢：宅者「阴阳之枢纽，人伦之轨模」；人以宅为本，宅安则家代昌吉，不安则门族衰微。术法分二十四路（十干、十二支、乾艮坤巽），配八卦九宫，定阴阳二宅：乾坎艮震及辰为阳，巽离坤兑及戌为阴；阳宅龙头在亥尾在巳，阴宅龙头在巳尾在亥。主旨「阴阳相得」——阳不独王以阴为得，阴不独王以阳为得；重阴重阳则凶。又立「五虚五实」：宅大人少、门大内小等为虚致贫，宅小人多、墙院完全等为实致富。修造须先修刑祸后修福德，依天德月德生气方位兴工，避四王神、死气。
⚡ Ứng dụng: 用于阳宅选址、布局与修造择日：辨阴阳二宅、福德刑祸方、五虚五实，指导门向、增拓与动土，以安人伦气运。

This text proves that a dwelling is a living yin-yang organism whose form channels qi to occupants; housing is therefore destiny infrastructure. It argues that human fortune is co-authored by residential polarity, proportions, and temporal use, not by personal virtue alone. Therefore correcting the house is a legitimate causal intervention in life outcomes.
1) In BaZi consultation, always couple chart reading with residence audit (light, damp, door-direction, bedroom yin). 2) Sequence: stabilize dwelling qi before expensive personal talismans. 3) Match house adjustments to chart deficiency (e.g., weak earth → ground/stability fixes). 4) Time renovations with luck pillars when possible. 5) Treat chronic family patterns as possibly house-mediated, not only natal.
Unlike葬书, which works through ancestral burial landscape,宅经 works through the living’s daily container. It differs from star-destiny scriptures by making architecture the medium of fate. Its logic is environmental rather than bureaucratic or purely ethical.
