Birth date sourced. Birth time unknown.Moon sign undetermined. The Moon crossed from Leo into Virgo during that day. Everything below uses only what the complete civil day settles.
The day, read honestly
Tightest of all, Mars holds a trine to Uranus at 0.5° — close enough to weld drive to disruption. The scheme reads trines as water finding its level: effortless, and invisible to the person living it.
Positions at 12:00 civil time in Shanghai County—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.
Where the Sun actually stood
18.0° of Sagittarius is the Sun's exact seat — second decan, 10°–20°, sub-ruled by Mars in the old triplicity scheme. The degree is the address; the sign is only the street.
The personal registers
The personal planets sit Mercury at 8.5° Capricorn, Venus at 1.9° Scorpio, Mars at 26.6° Taurus. Mercury in a earth sign reads as thought with its feet on the ground; Venus in a water sign reads as attraction that works by atmosphere; Mars in a earth sign reads as effort banked steadily until it tells.
The angles that hold
The tightest geometry in the chart puts Mars a third of the circle apart from Uranus, 0.5° off exact. A third of the circle is the tradition’s friendliest distance — same element, shared assumptions, no translation required. Behind it, Jupiter sextile Uranus at 3.0°, and Mars sextile Neptune at 3.4° — both still well inside the orbs this site uses. All of it stands whatever the hour was: each angle was tested from midnight to midnight before it was written down.
Figures in the geometry
The Sun makes no major aspect that survives the day; the old reading gives such a planet autonomy — it acts alone, sometimes loudly.
The classical map
Read against the old dignities, three placements stand out. Venus in Scorpio at 1.9° is in detriment — the planet opposite its home, working against the grain; Mars in Taurus at 26.6° is in detriment; Jupiter in Sagittarius at 0.1° is in domicile — the planet in its own sign, running on home rules. None of this ranks anyone; dignity describes footing, and footing can be worked with.
The shape of the whole
Among the 9 placements whose signs hold for the whole day, the elements divide 4 earth, 2 fire, 2 water, 1 air; by modality, 3 mutable, 3 cardinal, 3 fixed. Earth counts what remains: the built, the kept, the finished. Promise weighs less than delivery. Mars, Saturn, Neptune and Pluto were retrograde — motion that reverses only from this vantage point, and which the old reading treats as delay used for revision.
The Moon is genuinely open
The Moon crossed from Leo into Virgo during that day at the birthplace, travelling 14.1° between one midnight and the next. A birth time would settle it in a second; there isn’t one. So the Moon stays unnamed here — the alternative is a guess wearing the clothes of a fact.
