Compare mantic systems

Read systems against shared questions to identify common language, procedural differences and distinct limits.

Read differences by dimension; historical evidence labels do not imply predictive validity.

InputsOriginal character, script form, decomposition convention and contextCasting source, number selection, time and body/use convention
Procedural structureThe graph is split or recombined, interpreted through component meaning, homophones, stroke position, writing gesture and the situation; some schools add phases, trigrams or calendrical signs.Numbers are reduced by eight or six to obtain upper-lower trigrams and a moving line. The body and function trigrams are distinguished, then compared through phase production-control, seasonal strength, nuclear and changed figures, and situational signs.
FormationEarly graph-pun stories; rich Song records; Ming-Qing manualsInfluenced by Shao Yong's Song thought; received method chiefly visible in Ming-Qing texts
Evidence labelsTextually documented · Traditional attributionTraditional attribution · Contested lineage or date
TextsSong anecdotes of Xie Shi / Zichu / Ming-Qing character-divination manualsXinyi Guashu attributed to Shao Kangjie / Ming text on character reading and Plum Blossom numbers / Later editions titled Meihua Yishu
LimitsCharacter divination depends on graph structure, puns and improvisation, limiting repeatability. Retrospective ingenuity should not be presented as a fixed algorithm.Attribution to Shao Yong does not establish his authorship. Famous stories such as the plum-blossom omen belong to lineage narratives; their historical status requires independent evidence.
