Classical domain
Xīn — the Heart — sits at the centre of the dragon’s body and classically represents the seat of imperial authority and the heart of the celestial dragon. Tong Shu doctrine reads Xīn days as auspicious for the consolidation of authority, official appointments, and the formal recognition of leadership; cautious for inappropriate ascendancy or premature claims. The mansion’s classical domain encompasses the heart, the centre of authority, the emperor’s seat.
Auspicious activity register (Tong Shu doctrine)
Classical Tong Shu commentary records Xīn as broadly favourable for: official appointments, formal recognition, scholarly examinations, ancestor veneration, return from journey.
Cautious activity register
Classical commentary records caution for: marriage (classical commentary records caution), funerals, beginning of construction. 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. Xīn is mansion 5 of the Azure Dragon’s seven, sitting within the broader wood-element register of the eastern quadrant.
Why the lunar mansion alone is not enough
The Xīn (心) 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 Xīn (心) 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 Xīn’s classical register — the mansion is classically associated with the heart, the centre of authority, the emperor’s seat and its activity register reflects this domain.
Read the mansion against the event you are planning. Classical Tong Shu doctrine records Xīn as favourable for official appointments, formal recognition and cautious for marriage (classical commentary records caution), funerals.
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.

Classical Tong Shu commentary records Xīn as favourable for: official appointments, formal recognition, scholarly examinations, ancestor veneration, return from journey. The classical register reflects the mansion’s underlying domain — the heart, the centre of authority, the emperor’s seat. 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 Xīn mansion days?
Classical commentary records caution for marriage (classical commentary records caution), funerals, beginning of construction on Xīn 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.
