If you grew up with BaZi (八字) in Singapore, Malaysia, Hong Kong or Taiwan, Korean saju will look familiar the moment you see the chart: the same ten stems, twelve branches, five elements, ten gods. The calculation is essentially identical. The differences are in emphasis, interpretation and use, and they are large enough that a saju reading of your chart can feel like a different reading. Here is what changes.
What is the same
- The four pillars from year, month, day and hour, using the solar-term calendar.
- The day master as the self.
- The ten gods (십성 / 十神): officer, wealth, resource, output, companion, in their yin and yang forms.
- Ten-year luck pillars and annual pillars.
- Stem combinations, branch harmonies, clashes and punishments.
What Korean saju emphasises
- The day master’s strength above all. Korean readings spend most of their effort on whether the self is strong or weak in its season, and derive the “useful god” (용신) from that. Many BaZi schools do too, but Korean practice makes it the spine of the reading.
- Practical life-stage advice. Korean saju grew up as counsel for ordinary decisions: marriage, moving, changing jobs, naming a child. Readings are written as advice for the next few years rather than as a description of a fixed fate.
- Compatibility (궁합) as a standard product. Gunghap is a routine pre-marriage reading in Korea in a way that BaZi compatibility is not everywhere.
- Date selection (택일). Choosing a wedding, moving or opening date from the couple’s charts is a normal service.
- Less emphasis on symbolic stars. The many “shen sha” (神殺) stars common in some BaZi traditions are used sparingly in orthodox Korean readings; a few (peach blossom, travelling horse, nobleman) survive.
What Chinese BaZi emphasises
Depending on school: structure types (格局), the balance of ten gods, wealth and career analysis in more detail, Feng Shui integration, and in some lineages the symbolic stars. Hong Kong and Taiwanese readers often go deeper into structure classification than Korean readers do.
Why readings of the same chart feel different
A BaZi master may tell you your structure is “Direct Officer” and discuss it at length; a Korean reader will tell you your day master is weak in a metal month, that water is your useful god, and that the next three years favour study over launching. Both are reading the same eight characters; they answer different questions.
Which is right
Neither. They are dialects. If you have a BaZi reading you trust, a saju reading is a second opinion in a plainer, more decision-oriented register. Many readers in Singapore keep both.
Trying a Korean reading
