The 8 Bagua Sectors of Feng Shui (八卦)

The Bagua (八卦 Bā Guà, 'Eight Trigrams') is the eight-sector diagram that underpins Compass School (理氣 Lǐ Qì) and BTB Feng Shui. Each sector corresponds to one life area (wealth, fame, love, family, children, knowledge, career, helpful people) and one trigram from the I-Ching. The classical sources, particularly Joey Yap and Lillian Too, describe the Bagua as the foundational map used to design any space.

Compass School (理氣) is the classical Chinese tradition that uses a compass or luopan (羅盤) to determine sectors by physical direction. BTB Feng Shui (Black Hat Sect) is a Westernized adaptation popularized by Lin Yun and Lillian Too that maps sectors by entry direction, the front door is always the career sector. Both schools use the same eight trigrams and life-area assignments; they disagree on directional mapping.

Choose one school and stay with it, they don't combine. Joey Yap recommends Compass School for anyone willing to use a compass; BTB is easier for renters or those without compass access. The classical sources frame both as legitimate, but mixing them creates contradictions because their starting points differ.

The classical sources don't rank sectors as universally most important, they describe each sector as governing a different life area, and the most-impactful sector for any individual depends on what they're cultivating. That said, the family sector (east) is often described as foundational because everything else depends on the wellbeing of the people who live in the space.

For Compass School practice, a standard compass works, the luopan (羅盤) adds many concentric rings for advanced calculations, but for sector identification a basic compass is sufficient. Joey Yap's Feng Shui for Homebuyers walks through the standard 24-direction method using only a regular compass.

Yes, but classical practice usually focuses on 2-3 sectors at a time aligned with what you're cultivating that year. Lillian Too recommends a yearly refresh aligned with the Lunar New Year, choose 2-3 sectors, tend them attentively for 60-90 days, and observe what shifts. Activating all eight sectors simultaneously usually dilutes attention rather than amplifying qi.
