Tai Sui Insertion Method: Another Way to Read Your Relationship With Someone

Tai Sui insertion places the other person's birth-year stem (Tai Sui) into your own chart and reads where its four transformations land in your palaces, judging where two people connect, who gives more and where the bond sticks. Used for intimacy, family and partnership, it complements ordinary synastry, focusing on how the other's energy moves inside your chart.

Zi Wei Dou Shu

Ordinary synastry compares two charts; Tai Sui insertion puts the other inside your chart to see which domains they land in—ideal for who pulls whom and along what.

What This Question Is Really Asking

Synastry that only compares main stars misses energy interaction; insertion shows concrete flows like their Lu into your Wealth versus Ji into your Spouse, finer than vague sign-style matching.

The Underlying Logic

Take the other's birth-year stem and derive its Lu/Quan/Ke/Ji—the energy they bring into your chart.

Using your chart as the body, see where their transformations land: Lu is bond and benefit, Quan drive or control, Ke reputation and gentleness, Ji attachment and sticking point.

Relation reading: their Lu into your Life/Wealth/Career/Travel tends to help and favor; Ji into your family or Spouse means attachment, entanglement or磨合 needed.

It complements synastry and must still combine both natal charts, Spouse palaces and real interaction—never conclude from one set of transformations alone.

A Step-by-Step Way to Read It

  1. Confirm the other's exact birth-year stem
  2. Using your chart as body, derive their stem's four transformations
  3. Mark which of your palaces their Lu/Quan/Ke/Ji enter
  4. Read Lu/Quan/Ke for bond and help, Ji for attachment and sticking points
  5. Combine both Spouse palaces and real interaction
  6. Treat insertion as supplement, not replacement for natal and standard synastry

Three Common Mistakes

Mistake 1: Comparing only main-star match, ignoring energy flows

Mistake 2: Judging a relationship solely from one transformation set

Mistake 3: Getting the other's birth-year stem wrong, invalidating the whole read

Back to Your Own Chart

Tai Sui insertion gives a unique view: where the other's energy flows inside your chart. It does not replace synastry but makes concrete which domain a relationship fulfills—or tests—you in.

Reading Order

  1. Cast the natal chart first and locate the palaces and major stars tied to Tai Sui insertion method before judging anything
  2. Open the triple-direction of those palaces and count the auspicious, malefic and assistant stars separately
  3. Check where the natal Four Transformations land to set the chart's baseline tone
  4. Read the decade-limit transformations to see whether the Tai Sui insertion method line is activated in this stage
  5. Then read the annual transformations and the year's palace to pin down this year's trigger and timing
  6. Layer natal, decade and year before concluding, then decide how to act rather than labeling good or bad
