You Were Written Five Thousand Years Ago
Now Decoded in Plain Language

We offer Four Pillars (Bazi), Plum Blossom, Liu Yao divination, Qimen Dunjia and more. Bazi reveals your life pattern and decade-long fortune cycles. Plum Blossom answers one specific question at a time. Liu Yao excels at judging how events unfold and their final outcomes. Qimen Dunjia reads timing, direction, and strategic choices. Each system draws from classical texts and can be used complementarily.

Four Pillars and Qimen Dunjia require an accurate birth date, time, and location for precise charting. Plum Blossom and Liu Yao do not require birth data — just focus on your question. We recommend saving your birth profile first so it auto-fills during readings, eliminating repetitive entry and reducing input errors.

All charts are computed locally using deterministic algorithms: Bazi follows standard stem-branch and solar term rules; Plum Blossom adheres to the original classical text; Liu Yao uses the three-coin casting method from traditional texts; Qimen Dunjia follows classical palace arrangement methods. Interpretations are based on chart structure from multiple angles. Core chart data (stems, branches, stars, hexagrams, palaces) is fixed and unchanging.

Four Pillars requires an accurate birth hour to determine the Hour Pillar. If unknown, you can still view partial information using year, month, and day only, or try Plum Blossom or Liu Yao — these tools don't depend on birth data. For Qimen Dunjia asking about current matters, you can also use the present time to cast a chart.

Bazi is destiny analysis — it reveals your innate pattern and fortune cycles from birth time, answering 'What kind of person am I and how is my fortune?' Liu Yao is divination — it answers specific questions through coin casting, such as 'Will this succeed and what is the outcome?' They complement each other: Bazi sees long-term trends and personality; Liu Yao judges specific matters and timing.

All profile data is stored only in your browser's localStorage and never uploaded to any server. Chart calculations happen entirely on your device. During interpretation, only structured chart data (e.g., stems, branches, hexagram patterns, palace information) is transmitted — no personally identifiable information like your name. You can delete all data anytime in Settings.
