CAST ONCE · READ THE REASONS · LEARN
Coins, time and numbers are different inputs. All three lead to one Mei Hua first judgment and I Ching learning from the same cast. Choose the input you prefer; you do not need to cast twice.
Each throw forms a line, from the bottom up. Values 6 and 9 move; 7 and 8 stay still. Coins can produce zero to six moving lines. Every moving line reverses in the relating hexagram; no movement means no relating hexagram.
Open the three-coin studio →Time uses the captured local lunar date and two-hour period. The two-number method uses the first number for the upper trigram, the second for the lower, and their sum for a moving line. This edition adds no hour number to the number method. Both inputs have one moving line.
Start with time or numbers →The browser calculates body and use from the selected rule, then compares their Five Phases: harmony, support, active effort, depletion or constraint. Where applicable it compares use after change while body stays fixed. No AI chooses or changes the cast.
For coins with zero or multiple moving lines, YiPhase follows its stated Guanbian edition convention. Read the role labels and numbered explanation in your result rather than assuming all traditional schools make the same selection.

Open the primary hexagram’s judgment, the selected classical passages and the relating hexagram when one exists. Body/use selection and classical passage selection are explained separately. The text gives you a way to examine stages, conditions and choices; it is not a second cast or a numerical probability.

Ask what you should understand before following up. Whichever input you choose, first inspect the calculated relationship: does the situation support the subject, demand resources or impose a constraint? Then study the same cast’s lines and text to consider timing and how conditions might develop.
Check the interpretation against actual deadlines, resources and responses. A favourable judgment does not establish approval, market demand or future facts.
铜钱、此时此刻、两个数字是不同的成卦输入。三种都先给体用五行关系初判，再沿用同一卦展开《易经》学习。时间与数字各有一动；铜钱可有零至六动，按观变本版规则选择体用。变卦翻转所有实际动爻；无动不造之卦。初判与经文取辞分别说明，不把两层机械相加，也不重新起一卦。
Traditional references: Mei Hua Yi Shu, volume 1 (numbers and calendar examples) and volume 2 (body/use). YiPhase’s wording, project example and edition choices are modern educational material.
