Classical domain

Dǒu — the Dipper — opens the Black Tortoise’s northern quadrant. The mansion classically presides over the measurement and storage of fortune, the granary, and the formal weighing of resources. Tong Shu doctrine reads Dǒu days as auspicious for harvests, the opening of granaries, and the formal accounting of wealth; particularly favourable for businesses that handle stored value. The mansion’s classical domain encompasses the dipper, the granary, the measurement of fortune.

Auspicious activity register (Tong Shu doctrine)

Classical Tong Shu commentary records Dǒu as broadly favourable for: opening a business, harvests, the storage of wealth, formal accounting, signing of contracts that involve measured exchange.

Cautious activity register

Classical commentary records caution for: speculative ventures, gambling, matters that depend on chance. 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.

Black Tortoise context

The Black Tortoise (a tortoise entwined with a serpent) governs the northern quadrant — the winter constellations, the water element, and the register of stillness, longevity, and the deep waters. Its 7 mansions span the structures of the household and storehouse. Dǒu is mansion 1 of the Black Tortoise’s seven, sitting within the broader water-element register of the northern quadrant.

The Dǒu (斗) 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 Dǒu (斗) 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 Dǒu’s classical register — the mansion is classically associated with the dipper, the granary, the measurement of fortune and its activity register reflects this domain.
• Read the mansion against the event you are planning. Classical Tong Shu doctrine records Dǒu as favourable for opening a business, harvests and cautious for speculative ventures, gambling.
• 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.
