- Reading focus
- Association alone cannot attribute surviving passages to Shao Yong.
Definition and details
Tieban, also written Iron Plate, links birth information and numerical indices with collections of interpretive passages. Lookup differs from reading hexagram lines, but a large passage count does not supply the complete procedure. Edition descriptions note limited algorithmic explanations, so examine inputs, index generation and lookup rules together rather than assuming one follows from the others.
Structure and history
Traditional claims associate it with Shao Yong or Huang Ji Jing Shi, but association does not establish his authorship of surviving passages. Compare the actual cycle text with later lookup collections. A modern edition description documents its presentation without independently identifying the first author or date; missing evidence should not be filled with a Song legend.
A concrete example
A concrete edition issue is whether a witness contains passages alone or also initialization rules and tables. Separate its procedural contents from indexed readings and test whether the index follows from stated inputs. If personal family information enters a verification step, record that additional input instead of describing the procedure as a blind reading.
Context and limits
Verification can document consultation interaction without validating forecasts, especially when known answers guide index selection. State the limits of uncertain textual history instead of claiming a sole secret lineage. This entry uses no real birthdays or family records and makes no lifespan, wealth or character judgments; its focus is witness structure, input dependence and unresolved provenance.
References & further reading
Historical sources document ideas and rules of their time, not empirical proof of predictive accuracy. Source notes identify the nature and scope of each reference.
