Classical domain
Jǐng — the Well — opens the Vermilion Bird’s southern quadrant. Classically presides over fresh water, the village well, and communal resources that the household and city depend on. Tong Shu doctrine reads Jǐng days as favourable for the digging of wells (literal and metaphorical), the establishment of public utilities, and matters that depend on shared resource. The mansion’s classical domain encompasses the well, fresh water, communal resource.
Auspicious activity register (Tong Shu doctrine)
Classical Tong Shu commentary records Jǐng as broadly favourable for: digging of wells, establishment of public utilities, opening of public services, ancestor veneration, formal sharing of resource.
Cautious activity register
Classical commentary records caution for: hoarding, secretive negotiations, demolition of communal structures. 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. Jǐng is mansion 1 of the Vermilion Bird’s seven, sitting within the broader fire-element register of the southern quadrant.
Why the lunar mansion alone is not enough
The Jǐng (井) 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 Jǐng (井) 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 Jǐng’s classical register — the mansion is classically associated with the well, fresh water, communal resource and its activity register reflects this domain.
Read the mansion against the event you are planning. Classical Tong Shu doctrine records Jǐng as favourable for digging of wells, establishment of public utilities and cautious for hoarding, secretive negotiations.
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 井 (Jǐng) mansion mean in classical date selection?
Jǐng (井), the Well, is mansion 22 of 28 in the classical lunar-mansion cycle — one of the seven mansions of the Vermilion Bird (朱雀) quadrant of the night sky. Classical Tong Shu doctrine reads Jǐng as the well — fresh water and communal resource. favourable for public utilities and shared ventures.
What is the Jǐng mansion classically auspicious for?
Classical Tong Shu commentary records Jǐng as favourable for: digging of wells, establishment of public utilities, opening of public services, ancestor veneration, formal sharing of resource. The classical register reflects the mansion’s underlying domain — the well, fresh water, communal resource. 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 Jǐng mansion days?
Classical commentary records caution for hoarding, secretive negotiations, demolition of communal structures on Jǐng 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.
