Sha Formations

Through-Hall Sha (穿堂煞)

The term is widely discussed in Chinese media; treat symbolic wealth claims as cultural framing, not financial advice.

Definition

Through-hall sha occurs when the front door and a rear window or balcony align on one straight line, so incoming air rushes out without circulating. Form School texts describe this as ‘leaking qi,’ symbolically linked to difficulty retaining wealth and stable rest.

How to Check

Stand inside the door and see whether you can sight straight through to the rear opening.
On the floor plan, draw a line from the door centre to the rear window centre; an unobstructed line confirms the pattern.
Note whether strong cross-drafts appear whenever the door opens.

Classical Basis

Yang-dwelling classics warn against ‘one arrow through the heart’ layouts where door and rear opening oppose. The remedy tradition favours bending airflow rather than blocking it entirely—screens, vestibules, or opaque curtains mid-path.

Application

·Common in compact apartments with balcony doors behind the living room.
·Evaluate before buying: retrofitting may be limited in rental units.

Common Effects

·Cross-ventilation can improve air exchange but may feel drafty at rest zones.
·Traditional readings associate straight leakage with unstable finances; modern readers often map this to poor thermal comfort.
·Sightlines through the home reduce privacy in the entry sequence.

Remedy Direction

Insert a visual and airflow break—entry screen, bookcase, or layered curtains—so qi ‘turns’ before exiting. Placement must follow the full house chart; blocking the wrong zone can create new pressure points.

Caveats & Debate

Architects may prize through-flow for daylight; feng shui prioritises curved retention. Compromise solutions often combine partial screens with mechanical ventilation.
