The classical Water Formula (Dragon Gate Eight Directions, 龍門八局) was developed for landscapes with literal rivers, streams, and ponds. Modern cities replace nearly all of those with engineered analogues — streets, freeways, drainage culverts, traffic circles, even underground subway lines. San He practitioners since the 1960s have extended the formula to treat these urban features as water proxies, with the same direction-and-flow logic governing wealth and energy outcomes. The extension is widely accepted in the modern Singapore, Hong Kong, and Taiwan schools, and the case-study pattern is by now well-developed.
Streets as water: the proxy mapping
Energetically, water and traffic share the same key behaviours: directional flow, varying speed, accumulation in pools (intersections, plazas, parking lots), and exits via drainage paths. The proxy mapping is direct. A QUIET RESIDENTIAL STREET = a slow stream (gentle, sustainable energy). A BUSY MAJOR ARTERY = a river (strong directional energy that can support or drain depending on flow direction relative to the property). A FREEWAY = a high-volume river (the strongest urban water proxy; properties near freeways are deeply affected). A T-INTERSECTION = water rushing toward a point (the classic feng shui 'sha' configuration if the intersection points at the front door). A TRAFFIC CIRCLE = a swirling pool (concentrating energy that can be auspicious if positioned correctly or chaotic if not). The Water Formula's auspiciousness lookups apply unchanged once the urban feature has been classified by its proxy type.
Case study: a south-facing apartment overlooking a busy avenue
A typical urban audit case: a Li-trigram-facing apartment on the third floor of a building, overlooking a wide six-lane avenue with traffic flowing roughly east-to-west during morning peak and reversing west-to-east in the evening. Water Formula analysis: (1) the avenue is a strong river-class water proxy. (2) The morning east-to-west flow brings energy into the property from the auspicious east position, then exits through the west — this is a favourable approach pattern for a Li-facing structure. (3) The evening reversal is energetically negligible because residents are typically inside and not exposed to the inflow direction. (4) The traffic intensity is significant but not 'crashing' (no T-junction at the property line). Conclusion: the configuration is mildly favourable for the property, particularly for the financial and visibility-related life domains. Classical water-feature rules also apply — adding a small interior fountain pointed AWAY from the avenue (toward the apartment's back rooms) further activates the inflow capture.
When the urban configuration is hostile
Some urban configurations are unambiguously hostile and hard to remediate. Properties at the END of a T-junction with traffic flowing directly toward the door experience accelerated energetic friction — the auditing pattern is consistent across the case-study literature: tenants report higher illness rates, financial volatility, sleep disturbance, and accident frequency. Practical urban remediations: (1) tall hedge or solid fence between the road and the property (most effective); (2) a curved walkway from the property line to the door, breaking the line; (3) a heavy water feature placed in the direct flow path to absorb and diffuse the rushing energy; (4) at last resort, a Ba Gua mirror placed externally facing the road (legally controversial in many jurisdictions and aesthetically intrusive — practitioners typically advise the owner to consider relocating before resorting to this). The freeway-adjacent variant (property within ~50m of a freeway with no visual or sound barrier) is held by many practitioners to be unredeemable for residential use; commercial use can sometimes work because the high-energy flow supports certain types of business but is not compatible with rest.
