Classical domain

Kàng — the Neck — classically associated with disease, plague, and the throat’s inability to voice what is wrong. Tong Shu doctrine reads Kàng days as broadly cautious for major undertakings; classical commentary specifically warns against beginning long-cycle work, marriages, or burials on Kàng days. The mansion’s classical domain encompasses disease, plague, hidden grievances, the throat and what it cannot voice.

Auspicious activity register (Tong Shu doctrine)

Classical Tong Shu commentary records Kàng as broadly favourable for: hunting, repair of fishing nets, daily routine maintenance.

Cautious activity register

Classical commentary records caution for: marriage, burials, beginning new construction, contracts, journeys, formal ceremonies. 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.

Azure Dragon context

The Azure Dragon governs the eastern quadrant of the night sky — the spring constellations, the wood element, and the register of growth, ascension, and scholarly emergence. Its 7 mansions describe the dragon’s anatomy from horn to winnowing basket. Kàng is mansion 2 of the Azure Dragon’s seven, sitting within the broader wood-element register of the eastern quadrant.

The Kàng (亢) 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 Kàng (亢) 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 Kàng’s classical register — the mansion is classically associated with disease, plague, hidden grievances, the throat and what it cannot voice and its activity register reflects this domain.
• Read the mansion against the event you are planning. Classical Tong Shu doctrine records Kàng as favourable for hunting, repair of fishing nets and cautious for marriage, burials.
• 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.
