Definition: Flow and Obstruction tests whether a route works

Bazi (Eight Characters; also BaZi or Four Pillars) reads a chart through qi (seasonal and relational conditions), tian gan (Heavenly Stems), di zhi (Earthly Branches), and the Five Phases. This article uses liu tong (Flow) and zu zhi (Obstruction) as a paired method. Flow asks whether a named relationship can move from source through transitions to a receiver or expression. Obstruction asks where that route is weakened, diverted, cut off, overextended, or left without a usable endpoint. The method is about chart evidence, not about counting elements or predicting a fixed event.

A flow claim must identify an object. It might concern a Day Master route, a Pattern, a climate function, a source-to-output chain, or a temporary timing layer. “The chart flows” is too vague to review. A more useful statement names the starting evidence, each transition, the receiver, and the condition that interrupts it. Flow is not the same as balance: a chart can contain all five phases and still have a blocked route, while a chart dominated by two phases can show continuity under a stated school rule.

Textual and historical context

The concern with continuity, interruption, generation, control, and appropriate function appears across received readings of Di Tian Sui (The Marrow of Heaven), Zi Ping Zhen Quan (The True Principles of Zi Ping), Qiong Tong Bao Jian (a seasonal Bazi manual), Yuan Hai Zi Ping (The Deep Sea of Zi Ping), San Ming Tong Hui (Comprehensive Collection of the Three Fates), and Shen Feng Tong Kao (a Bazi compendium). These works are not one modern textbook. Their editions, commentaries, attributions, and priorities differ, so this article treats their shared vocabulary as a comparison field rather than assigning one universal formula to all of them.

The Chinese Text Project is useful for checking received wording and locating scans or metadata, but its own introduction explains that transmission can involve variant copies, later corrections, and difficult questions about what counts as an accurate text. Its guidance on the collaborative Wiki also warns that some entries may not be proofread. That is why this article does not build its method on a long quotation or an unverified author-date claim. A classical image of continuity can prompt a question; later commentary, a school rule, modern teaching synthesis, and Mystic Atlas editorial guidance must still be labeled separately.

Prerequisites and a repeatable reading sequence

Read bazi-source-and-flow first, because it maps where a route begins and what it is meant to reach. Then review bazi-structure-and-function, bazi-roots-and-rooted-qi, bazi-stem-exposure, bazi-seasonal-command, bazi-climate-regulation, bazi-support-and-restraint, and bazi-illness-and-remedy. Use bazi-reading-order to verify the chart before drawing a route. Keep one charting convention visible, especially for solar-term boundaries and Hidden Heavenly Stems.

  • 1. Verify the birth date, clock time, location, historical time zone, solar-term boundary, four pillars, and the selected branch-content table.
  • 2. Name the object of the test: Day Master support, a Pattern line, a source-to-expression route, climate regulation, or a timing layer. Do not test an undefined “whole life.”
  • 3. Mark the source and receiver. A source may be seasonal qi, a root, a visible stem, a generating phase, or a newly arriving time layer
  • a receiver may be the Day Master, an exposed function, or an intended output.
  • 4. Draw each transition in words: generates, supports, controls, drains, releases, combines, or redirects. Do not call every generation sequence helpful.
  • 5. Test continuity at each step. Check season, root, exposure, position, distance, source quality, and whether another relation changes access.
  • 6. Locate the obstruction precisely. Record whether it is missing support, excessive control, a broken bridge, competing mixture, environmental mismatch, or a route that reaches no receiver.
  • 7. Compare Flow and Obstruction with Pattern, Support and Restraint, Climate Regulation, or Illness-and-Remedy. State which method leads instead of silently changing frameworks.
  • 8. Write a conditional result: continuous, partial, diverted, obstructed, or unresolved, and state what evidence could change it in a luck pillar, annual layer, or alternate chart.

How to tell a real obstruction from a missing symbol

Absence is not automatically obstruction. A phase can be absent from the visible stems yet represented through branch contents or a seasonal route. Conversely, a phase can be present and still be functionally unavailable because it is unrooted, combined away, out of season, exhausted, or unable to reach the object. The key question is not “Which element is missing?” but “Which transition does the missing or unusable evidence prevent?” This keeps Flow and Obstruction distinct from a missing-element checklist.

  • Source failure: the proposed route has no credible beginning or its source is too weak for the selected rule.
  • Transmission failure: a phase is present but cannot pass to the next step because of distance, control, combination, or competing structure.
  • Receiver failure: a route arrives at an object that cannot receive, express, or contain it under the chosen method.
  • Overload: flow exists but becomes excessive, drains the receiver, or creates a second obstruction.
  • Timing obstruction: a luck or annual pillar exposes a limitation or changes access temporarily
  • it does not rewrite the natal chart.

Fictional teaching example

This is a fictional teaching example, not a real person or a prediction. Assume a jia (Yang Wood) Day Master born in a Shen (Monkey) Month Command, with an Yin (Tiger) Day Branch, a visible ren (Yang Water), and a visible geng (Yang Metal). A source-first reading proposes a Metal-to-Water-to-Wood route: geng may supply Water, ren may nourish Wood, and Yin may provide a direct Wood root. The route is only a hypothesis. Shen and Yin may contest the root, autumn conditions may privilege Metal, and another Earth relationship could interrupt or redirect Water.

The worksheet therefore records three different findings: Metal-to-Water is a possible source transition; Water-to-Wood is a possible receiving transition; and Wood’s root is present but contested. A Bridging reader may ask whether Water connects Metal and Wood. A Support and Restraint reader may ask whether jia can receive the pressure. A Climate Regulation reader may ask whether the seasonal environment changes Water’s usefulness. The responsible conclusion is limited: the chart shows a partly continuous route with a contested receiver, not a guaranteed career, relationship, health, or wealth result.

Commentator and school differences

Some teachers use Flow broadly for any productive sequence among the Five Phases. Others require a visible chain, a recognized Pattern, or a route that reaches a useful endpoint. A Month Command approach begins with seasonal authority; a whole-chart approach may rank roots, exposed stems, and party support across all four pillars; a Pattern approach may reject an attractive flow if it breaks the governing structure. Climate-oriented readers may interrupt a neat generation chain by asking whether cold, heat, dryness, or moisture prevents the expected function.

Schools also disagree about obstruction. One reader may treat a clash as opening or redirecting a route, while another gives it priority as a break in continuity. Some allow a luck pillar to supply a temporary bridge; others treat timing as activation of natal potential only. These are not details to hide after the fact. State the rule, apply it consistently, and preserve an alternative when the rank of the same evidence changes the route.

Common errors

  • Counting repeated phases and calling the result flow without naming a source, receiver, or transition.
  • Treating every generation relationship as beneficial and every controlling relationship as harmful.
  • Equating a missing visible stem with total absence, or a present sign with usable function.
  • Using a later pillar to erase natal obstruction rather than describing a temporary change in access.
  • Confusing Flow and Obstruction with Source and Flow, Bridging, Support and Restraint, or Illness-and-Remedy.
  • Turning a structural blockage into a diagnosis, a fixed personality claim, or a prediction about wealth, marriage, death, crime, disaster, or another person’s private intentions.

Terminology translation note

This article adopts Flow and Obstruction for the paired working terms liu tong and zu zhi. English variants include circulation and blockage, continuity and interruption, passage and impediment, and movement and obstruction; they are not stable synonyms across schools. I retain liu tong when discussing the curriculum method and use Flow in ordinary explanation. Zu zhi is treated as a descriptive obstruction, not a claim that a person is blocked. Qi remains a traditional model of seasonal and relational conditions, not a scientifically measured energy. Rootedness is the adopted rendering for tong gen, Stem Exposure for tou gan, and Pattern for ge ju.

Bazi is presented as a traditional interpretive system, not scientifically validated prediction. Flow and Obstruction can make a reading auditable by exposing its route and failure points, but they cannot diagnose illness, decide medical, legal, or financial action, determine marriage or wealth, infer crime or disaster, read a third party’s mind, or replace professional advice.
