ZI WEI DOU SHU · CHART & READING LOOKUP
Enter a birth date and time. Get a chart that names every star in all twelve palaces.
Zi Wei Dou Shu (Purple Star Astrology) is a traditional Chinese chart method. This site builds the chart deterministically, corrects clock time to true solar time using birth longitude, the equation of time and Chinese daylight-saving history, then lets you read 13 sections of pre-edited traditional commentary for that exact chart.
The chart interface itself is in Chinese — the palace and star names are Chinese terms, so an English translation layer would only add noise. This page explains the service in English before you pay.
WHAT THIS DOES
- Deterministic star placement, transformation stars, major-decade and annual luck — the full classical rule set
- True solar time correction, including the 23:00 late-Zi day rollover
- A lookup library keyed by 674,976 exact birth-parameter combinations × 13 reading sections (514,733 distinct reading sets)
- Full-text search across public-domain classical texts
WHAT THIS IS NOT
- Not generated at request time and not a chatbot: the text is pre-edited reference material retrieved by chart key
- Not a consultation — no practitioner reviews your chart
- No rituals, cures, luck-altering products or amulets are sold here
- Not medical, psychological, legal, investment or life advice
Positioning and eligibility
Everything on this site is presented as cultural heritage and self-reflective reading material, for entertainment and study only. We make no claim that any passage predicts future events or produces a verifiable outcome, and we sell no service that promises to change fortune. Same birth chart, same text — the library is a fixed corpus, not a reading tailored to change your choices. Content is intended for users aged 18 and over.
How it works
1
Enter birth data
Date, time as exact as you know it, and birth city. The form shows the corrected solar time live, and whether the chart rolls to the next day.
2
Read the free chart
All twelve palaces, major and minor stars, transformation stars, current decade and year. This step costs nothing and needs no email.
3
Unlock the 13 sections
Chart overview and personality each open with about 380 characters free; unlocking covers the full text of all 13 — relationships, career, wealth, health, family, relocation, property and more.
Pricing
Priced in US dollars. Payment is handled end-to-end by a third-party Merchant of Record, which is the seller of record for tax purposes — sales tax / VAT is calculated and remitted by them, and they issue the receipt. We never see or store card numbers.
Free
$0
The chart itself, plus the first 380 characters of each of two reading sections — chart overview and personality. The other eleven sections stay locked.

$6.9
Full text of all 13 reading sections for that one chart, yours to re-read for as long as the site exists. Best if you only want your own chart.
PRO monthly
$12.9/mo
Full text for every chart, so you can look up family and friends too. Cancel any time; access runs to the end of the paid period.
PRO yearly
$99/yr
Same full text as monthly, about $8.25 a month — $56 less than twelve months billed monthly.
Questions before you pay
There are no accounts — what if I switch devices?
Your entitlement is tied to the email address you typed at checkout. Nothing else identifies you. On a new device, unlock the same chart and choose "restore", then enter that email. That is why the checkout form insists on a mailbox you can actually receive mail in — there is no password reset.
I do not know my birth hour.
You can still build a chart, but the hour decides how all twelve palaces are laid out, so a reading only holds for the hour you picked. Build a chart for free first; do not buy a chart you are guessing at.
My birthday falls near 23:00, or in a daylight-saving year.
Both are handled before the chart is built: mainland China observed DST from 1986 to 1991, and the late-Zi hour convention shifts the chart day. The corrected date and the chart key used for the lookup are shown above the reading, so you can check them.
Is it accurate?
It is traditional literature, organised and rephrased for reading. Accuracy is not guaranteed and not claimed. If you are dealing with a mental or physical health concern, see a qualified professional instead.
Refunds?
Within 7 days of purchase, if you opened no more than 2 unlocked sections, write to
support@xinliai.vip and we refund in full through the original payment channel. Substantial prior reading counts as consumed. See section 4 of the Terms.
