This is the course’s terminology contract.

The working interface is English. Pinyin and Chinese characters are precision labels for cross-checking sources, not the thing a reader has to decode first. When a module introduces a technical term, use this order:

English working label → pinyin if useful → source notation → plain-English job.

Example: World line (Shi, 世) = the querent’s position in the cast.

Position Markers

English working labelPinyinSource notationPlain-English job
World lineShiThe querent’s position in the cast.
Response lineYingThe answering position, counterpart, or external mirror.
Target lineYong Shen用神The line that represents the question being asked.
Support lineYuan Shen原神The line that generates or supports the target line.
Opposing lineJi Shen忌神The line that controls or obstructs the target line.
Drain lineChou Shen仇神The line that drains the support line or indirectly weakens the target.

Use World line, Response line, Target line, Support line, Opposing line, and Drain line in body prose. Use pinyin only when naming the source term or when a later module needs the exact classical label.


The Five Line Roles

These are traditionally called the Six Relatives even though the working set contains five visible relationship labels. Use the English role first.

English working labelPinyinSource notationPlain-English job
Parent lineFu Mu父母Parents, documents, shelter, protection, support structures.
Officer lineGuan Gui官鬼Illness, pressure, authority, official matters, danger, employment.
Sibling lineXiong Di兄弟Siblings, peers, rivals, competitors, equals, resource drain.
Wealth lineQi Cai妻財Money, assets, spouse in traditional male-centered case categories, tangible goods.
Child lineZi Sun子孫Children, medicine, relief, output, creativity, release from pressure.

The source term Six Relatives (六親) can appear in headings and tables, but explanatory prose should say line roles or five line roles unless the source label itself matters.

Style Rules For Course Pages

  1. Use the English label in headings and first explanations.
  2. Add pinyin and source notation on first mention when they help the reader cross-check source material.
  3. Do not rely on Chinese characters alone to carry meaning.
  4. Do not stack several Chinese terms without an English paraphrase.
  5. Treat source notation as a precision layer, not as decoration.
