Ancient arts,
in plain words.
Yuen Chi Lab has spent years studying Qimen Dunjia and Zi Wei Dou Shu, writing the rules of the classical texts into software, one by one. Charts are checked against independent tools; readings list what is likely to happen, in plain language, with the reason behind each point.
One asks about a single matter. One looks at a whole life.
Qimen Dunjia
Pick what you want to ask. Yuen Chi Lab casts a Qimen chart for the moment you ask, finds the element that stands for your question, and tells you point by point what favours you, what works against you, and what is likely to happen.
- 20+ question types: work, marriage, investment, exams, renting, loans, lawsuits, illness…
- Three chart methods: Chai Bu, Zhi Run and Yin Pan
- True solar time, worked out from your location
- Life chart: cast from your birth time
Zi Wei Dou Shu
Enter your date and time of birth. We draw the twelve-palace chart and read it by topic — character, money, marriage, children, health and each ten-year period — every point in plain words.
- Your whole life, each decade and each year
- A free preview first; pay only if it fits
- The people around you too: spouse, children, parents
- The whole twelve-palace chart at a glance
Not just good or bad — what is likely to happen.
Most charting apps hand you a chart and leave you to it. A Yuen Chi Reading reads the chart for you: it lists the concrete things likely to happen, and states the chart reason after each one. If you want to dig deeper, the classical text and its source are attached too.
Your superior does not bear down on the job: the position is stable.
The job works against you: progress will not be smooth.
Friction with the people under you.
The people in this workplace: refined and courteous.
Many of life's ups and downs run along one line: work → children and partnerships → home and property.
In marriage, the wife carries an unusually heavy load of ability and responsibility — more than is good for her.
2035–2044: friendships are where this decade hurts most.
No major weak point in the natal chart.
Every line has a basis; anything the classics do not say is clearly marked as a modern reading.
A tool if you know the arts. Answers if you don't.
A tool that fits the hand
Fast charting, a dictionary of doors, stars and spirits, formations at a glance, the classical texts side by side — no more ten browser tabs.
Straight to the answer
Choose what you want to ask, tap once, and get a plain-language conclusion with its reasons. No need to learn the nine palaces first.
The arts can be written down clearly — with sources.
Rooted in the classics
Rules come from texts such as the Dunjia Yanyi, the Qimen Dunjia Tongzong and the Gujin Tushu Jicheng.
Every chart checked
Charts are compared with independent tools and worked examples from the books; what fails the check does not ship.
True solar time
Converted from the longitude of your birthplace or location, so hour boundaries come out right.
Old and new side by side
The classical line and its modern plain-language version, shown together.

a discipline with rules
and sources.
Yuen Chi Lab has spent years studying Qimen Dunjia and Zi Wei Dou Shu. We gather the rules scattered through the classical texts, write them into software one by one, and check them against a large number of real charts.
We want practitioners to find it a pleasure to use, and newcomers to understand what they read — every conclusion comes with its reason.
