Classical domain
Bì — the Net — classically the hunting net, the apparatus by which fortune is caught and held. Tong Shu doctrine reads Bì days as favourable for the capture of opportunity, the formal commitment to a course, the binding of agreements, and hunting (in the literal classical sense). The mansion’s classical domain encompasses the hunting net, the catching of fortune, formal capture.
Auspicious activity register (Tong Shu doctrine)
Classical Tong Shu commentary records Bì as broadly favourable for: hunting, capture, formal commitment, signing of binding agreements, marriages with strong commitment register.
Cautious activity register
Classical commentary records caution for: releases, the freeing of obligations, severance. 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.
White Tiger context
The White Tiger governs the western quadrant — the autumn constellations, the metal element, and the register of judgment, harvest, and martial strength. Its 7 mansions describe the tiger’s anatomy and the regalia of authority. Bì is mansion 5 of the White Tiger’s seven, sitting within the broader metal-element register of the western quadrant.
Why the lunar mansion alone is not enough
The Bì (畢) 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.
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.
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.
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.
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 Bì (畢) 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.
Practical priorities
Note Bì’s classical register — the mansion is classically associated with the hunting net, the catching of fortune, formal capture and its activity register reflects this domain.
Read the mansion against the event you are planning. Classical Tong Shu doctrine records Bì as favourable for hunting, capture and cautious for releases, the freeing of obligations.
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.
What does the 畢 (Bì) mansion mean in classical date selection?
Bì (畢), the Net, is mansion 19 of 28 in the classical lunar-mansion cycle — one of the seven mansions of the White Tiger (白虎) quadrant of the night sky. Classical Tong Shu doctrine reads Bì as the net — the hunting register and capture of fortune. favourable for binding commitments.
What is the Bì mansion classically auspicious for?
Classical Tong Shu commentary records Bì as favourable for: hunting, capture, formal commitment, signing of binding agreements, marriages with strong commitment register. The classical register reflects the mansion’s underlying domain — the hunting net, the catching of fortune, formal capture. Note that the lunar mansion is one of four inputs into any complete date-selection reading; chart-specific application requires layering in the day’s stem-branch pillar, the year and month context, and your own BaZi chart.
Should I avoid events on Bì mansion days?
Classical commentary records caution for releases, the freeing of obligations, severance on Bì days, but the caution is descriptive rather than prescriptive. Whether the cautious register actually applies to your specific event depends on the day’s stem-branch pillar, the year/month context, and your own chart. A chart-aware date selection consultation reads all four layers together to determine whether a candidate date is genuinely contraindicated for you.
