Reviewed definition
East-Four and West-Four Mansions (東四宅與西四宅) is a technical term within feng shui and Yijing-related knowledge systems. Specifically, The Eight-Mansions grouping of Kan, Li, Zhen and Xun as East-Four houses and Qian, Kun, Gen and Dui as West-Four houses. It is a symbolic classification within that method, not a building-quality grade. This library explains it within the schools and methods domain and distinguishes historical description, lineage rules, observable spatial data and later symbolic interpretation.
Historical context
The modern meaning of this term accumulated through classical texts, commentaries, regional practice and later systematization. Review used “Form School Approach to Feng Shui and Sustainable Design” for historical, textual or material context; that source does not establish that every later lineage uses the term identically.
Modern-use note
Today, East-Four and West-Four Mansions may be used in terminology teaching, source indexing, case annotation, compass or landform documentation and comparison of lineage rules. Professional records should state edition, directional reference, scale, date, observations and uncertainty so another reader can trace the reasoning.

Limitations and cross-cultural caution
This term records a cultural, historical or lineage-specific interpretive framework. It must not be presented as established scientific causation or a guarantee of health, wealth, relationships, examinations or investment outcomes. Building, structural, fire, environmental, medical, legal and financial matters require applicable rules, measurements and qualified advice.
Cross-cultural writing should retain 東四宅與西四宅 with a transliteration or conventional translation. Japanese “東四宅・西四宅”, Korean “동사택·서사택” and English “East-Four and West-Four Mansions” may have different local ranges; similar labels do not make methods, historical authority or practical conclusions identical.
