Najia six-line chart

Review stem/branch assignments, host/response, Six Relations, Six Spirits, ten-day-cycle void, trines, fanyin and fuyin.

Current scope

Assign stems and branches, five phases, six relations, and host and counterpart roles to the six lines. Results from coin or yarrow casting also show changing and changed lines. This tool checks chart structures; it does not issue auspicious or inauspicious predictions.

The chart includes eight palaces, Najia, six relations, host and counterpart roles, changing-line changes, month and day branches, and ten-day-cycle void branches. Optional layers show six spirits, hidden lines, seasonal status, branch relations, fanyin and fuyin, and Yongshen candidates. Advanced relations are reproducible structural records, not judgments of fortune.

Conventions and sources

  1. Six relations compare each line’s branch phase with the phase of the original hexagram’s palace. The same trigram may therefore have different six relations in hexagrams belonging to different palaces.
  2. The date is first determined in the selected time zone. The calendar engine then calculates the solar-term month and day stems and branches. Month and day references use their branches; void branches derive from the ten-day cycle of the day pillar.
  3. The day stem determines the first line’s spirit; subsequent lines follow a fixed order upward. The site shows this arrangement, not automatic judgments of fortune from spirit names.
  4. Hidden lines use the missing-relation search: only when a six-relation category is entirely absent from the original hexagram is its matching line in the palace’s pure hexagram placed beneath the current visible line.
  5. Seasonal status uses the month branch’s phase as the ruling phase and marks each line as prosperous, supported, resting, confined or dead (phase status). Month and day clashes use opposite branches; voids use the day pillar’s ten-day cycle. These are displayed separately, not converted into fortune scores.
  6. Changed-line stems and branches use the matching Najia positions in the resulting hexagram. Six relations remain anchored to the original palace phase, not the resulting hexagram’s palace or host/counterpart roles.
  7. The branch-relation layer checks only fixed six-combination and six-clash pairs between original lines, the month and day branches, and other original lines. A month-branch clash is called month break. This layer does not infer fortune, phase transformation, activated trines or changed-line return relationships.
  8. Return generation/control compares the changed line’s phase acting on the original line’s phase. Advancing and retreating branches use only the seven advancing and seven retreating pairs explicitly listed in Zengshan Buyi. Labels do not automatically apply the original book’s predictions.
  9. First check completeness of 申子辰, 巳酉丑, 寅午戌 and 亥卯未. Activation is checked separately for all three moving, two moving and one static, inner lines one and three changing, or outer lines four and six changing. Complete static branches mean completeness only; month/day supplements are recorded only as supplements.
  10. Fanyin/fuyin checks require original changing lines and a resulting hexagram. Trigram fanyin uses opposite Later Heaven palaces; branch fanyin uses same-position clashes; fuyin requires three unchanged branches at matching positions in the inner or outer trigram undergoing change. The three layers are separate and do not automatically judge fortune.
  11. The Yongshen layer accepts only an explicitly selected self/host line or six-relation category. All matching candidates are listed without one ranking selecting for the user. Changed-line and missing-relation hidden candidates are separately marked. Yuanshen, Jishen and Choushen follow fixed phase relationships, not direct judgments of fortune.
