Eight-Line Guicang
The house system
A conventional chart stops at six lines. This one begins at eight, in the Guicang lineage. Primary, changed and postnatal charts are cast together; each line carries nine columns of parameters.

Know your fate. Don't bow to it.
Forty-five calculation systems, 189 lectures on the Yi and medicine, eleven learning games. An entire tradition in your pocket — with one rule printed on every page: a reading is counsel, not a verdict.
Three things you won't find elsewhere
Beyond six lines,
there is an eighth
Plenty of apps can cast a BaZi or Liu Yao chart. What makes this one worth installing is three systems we compiled ourselves — the source material exists nowhere else.
Eight-Line Xinyi
Plum Blossom meets Guicang
Two four-line trigram stacks form an eight-line pyramid, yielding primary, nuclear, reversed and changed hexagrams. Five phases follow the dual scheme of the sixteen Guicang hexagrams.
Read the systemSix Hexagrams of a Name
Name analysis, recast
Five-grid numerology on an 84-number Guicang scale, strokes counted as actually written — simplified as simplified, traditional as traditional. Then six hexagrams: primary, nuclear, reversed, changed, and both derivatives.

The Yi–medicine curriculum
189 lectures.
Say it clearly first.
The largest part of the app. Five stages, from the foundations of Yi learning to close readings of the medical classics. Every lecture carries seven layers and a note on provenance, the nature of the source, and where scholars disagree.
This is study, not practice: no diagnosis, no constitution judgements, no treatment advice. If you are unwell, see a doctor.
“Observe the patterns of heaven
to understand the turning of time;
observe the patterns of culture
to complete the world.”
Fifty lectures are complete; the rest have full tables of contents and are marked “in preparation”. We don't pass off half-finished work as finished.
Eleven learning games
Win a hand,
learn a hexagram
Two kinds: one costs a silver coin per day for unlimited play, the other pays coins for skill. No skins, no loot boxes, no designs to keep you hooked.
Past the cap you can still play — just without rewards.

FAQ
The questions we get first
Most charts, tools and games run offline. Only three things need the network: account sign-in, the first download of core computation data, and community sync. Face reading is always local — it produces a full report in aeroplane mode.
Charts, settings and profiles stay on your device by default and export as JSON. Only a device fingerprint (no birth data), core data downloads and community posts touch the network. No third-party analytics SDK.
Membership sets the unlock range; coins pay per use. Check-ins, games and posting earn coins, and a single premium reading can be unlocked without upgrading. Earning needs a connection; spending doesn't.
Windows is in closed beta; macOS is planned. Leave your email on the download page and we'll work through the list in order. Desktop and mobile share the same algorithms and profile format.
No. AI output is a cross-reference, and the page says so: your own judgement comes first. There are no “certain divorce” or “blood disaster” pronouncements here. Anyone who tells you that is frightening you.
We don't recommend it. These results are cultural study and entertainment, not labels to put on a child. Face reading, wellness and cycle tracking are cultural reference and self-recording, not medical advice.
