ZI WEI DOU SHU ・ DouShu.App
More than a chart. Flying stars, Lu–Ji paths and timing in your chart
can now be searched and traced.
Source layer × Source palace × Transformation × Landing × Reference layer × Reference palace
Transformations weave across palaces and time layers. Doushu turns that tangle into data you can search and trace: start from one condition, find the connections, then find when they happen.
The engine is checking 10 candidate years across layers
Search in depth.Set a source layer and palace, a transformation and how it lands, plus a reference layer and palace. The engine checks every layer in turn and lists the periods that match, with evidence.
The Doushu ecosystem
Doushu’s AI, your own AI, or you: all work from the same chart, search and trace results.
Doushu AI
Reading a screenshot easily garbles palaces, stars and transformations. Doushu AI receives the structured chart, search and trace results straight from the engine, then builds its interpretation on them. Visitors can ask a few questions free each day; signing in raises the limit.
Knowledge & Skills・In progress
With the help of large models, Doushu is turning generations of accumulated wisdom and experience into structured knowledge and analysis methods. The AI learns not only what things are, but what to search, what to trace, and which theory and cases to consult for each kind of question.
MCP
Through MCP, any AI agent that supports tool calls can use Doushu’s charting, search, Lu–Ji tracing and timing directly, with no need to read a chart image.Technical details

with methods you can check today.
