Classical domain

Yì — the Wings — classically the bird’s expressive instrument, presiding over music, dance, theatre, and the arts of expression. Tong Shu doctrine reads Yì days as favourable for performances, the formal opening of artistic ventures, ceremonies of celebration, and matters that depend on aesthetic expression. The mansion’s classical domain encompasses the wings, music, the arts of expression.

Auspicious activity register (Tong Shu doctrine)

Classical Tong Shu commentary records Yì as broadly favourable for: performances, the opening of artistic ventures, ceremonies of celebration, marriages with artistic register, scholarly examinations in the literary arts.

Cautious activity register

Classical commentary records caution for: severance, demolition, the closing of artistic ventures. The cautious register is descriptive of the mansion’s classical reading, not prescriptive of a fixed prohibition — chart-specific reading determines whether the caution applies in a given case.

Vermilion Bird context

The Vermilion Bird governs the southern quadrant — the summer constellations, the fire element, and the register of warmth, illumination, and ceremonial public life. Its 7 mansions describe the bird’s body and its environment of festival and celebration. Yì is mansion 6 of the Vermilion Bird’s seven, sitting within the broader fire-element register of the southern quadrant.

The Yì (翼) mansion is one signal in a complete date-selection reading — not the whole answer. Classical Tong Shu (通書) doctrine layers four inputs into any date selection.

1. The lunar mansion governing the date. The 28 Mansions cycle through the calendar in a fixed seven-day weekday-coupled rhythm, so each candidate date carries one mansion as its presiding register. This is the input these reference pages describe.
2. The day’s stem-branch pillar. Every calendar date is also a 60-jiazi day pillar — one of the 60 stem-branch combinations that cycle every 60 days. The day pillar carries its own register, classical activity associations, and clash-or-combination relationships with the chart of whoever the date is for.
3. The year and month context. The current Tai Sui (太歲, the year god), the month branch, and the running shen sha for the year all modulate the date’s register. A mansion classically auspicious for marriage may be partially neutralised if the date falls in a month that clashes with the bride’s zodiac.
4. The chart-specific question. The date is being selected for a specific person and a specific event. The combination of mansion + day pillar + year/month context + the person’s own BaZi chart determines whether the date is genuinely auspicious for them. The same date can be excellent for one person and contradicted for another.

This page describes the first input — the Yì (翼) mansion's register. The reading is a useful starting reference. It is not a substitute for a chart-aware date selection that layers in the other three. Master Sean Chan’s auspicious date selection reads all four layers against your specific event question.

• Note Yì’s classical register — the mansion is classically associated with the wings, music, the arts of expression and its activity register reflects this domain.
• Read the mansion against the event you are planning. Classical Tong Shu doctrine records Yì as favourable for performances, the opening of artistic ventures and cautious for severance, demolition.
• The mansion is one of four inputs. See the “Why the lunar mansion alone is not enough” section above for the full date-selection calculus that includes the day’s stem-branch pillar, year/month context, and your specific BaZi chart.
• Book a chart-aware date selection via the auspicious date selection consultation to layer all four inputs together for your specific event.
