Doesn’t Mia light up when there’s something to look after?
Sample letterChapter one
Mia’sspringlight
Saju writes the moment a child was born as eight characters. Mia’s own character is 丙, the sun in the sky. The old books picture this sun as warm, generous with everyone, and quick to say what it thinks.
丙 (byeong): one of the ten “heavenly stems”. It stands for the child’s own nature.

What is Saju (사주)?
Saju is a Korean way of reading a person through the moment they were born: the year, month, day and hour.
Those four moments become eight characters, which show how Wood, Fire, Earth, Metal and Water are balanced in your child.
We read that balance as temperament, not fortune, and turn it into how your child might like to be spoken to.
The longer explanation
Saju (사주, Four Pillars of Destiny) is a Korean system of character analysis rooted in thousands of years of East Asian philosophy. It maps a person's birth year, month, day, and hour onto a framework of the Five Elements (오행: Wood, Fire, Earth, Metal, Water) and the 60-cycle Sexagenary calendar (만세력). The result is not a fortune — it is a temperament profile: a structured description of innate personality traits, learning styles, relational tendencies, and elemental balance. SoMyung applies this framework specifically to children, helping parents understand why each child is wired differently and how to communicate with them more effectively.

Excerpt from a real letter
What the letter actually looks like
One scene from chapter three of a letter to the parents of a fictional child, Ava. Only spelling and a few awkward phrases have been corrected.
Chapter three · Moments they get misread
When a question comes too fast
What it looks like
From the outside, Ava may seem slow to answer, or she may start and then revise what she meant to say.
What’s going on inside
One traditional way to read this is that her ideas do not always come out through a wide, easy opening; they may need a moment to take shape before she is ready to say them.
What we often say
“Why don’t you answer right away?” can land as pressure to produce a finished answer before she has found where it begins.
Try saying
“Take a minute, then tell me the first part only.”
What to watch for
Watch whether that makes her more able to begin, changes nothing, or makes her shut down more. Stop if the prompt itself becomes the new struggle.
Chapter three has three scenes like this. The other chapters: the light your child was born with, five ways your child meets the world, you and your child, this year and the next six months, and three things to try this week.
Having many questions about your child means you are watching them closely
We answer those questions with the record of the moment they were born.
Why so shy with strangers?
Who do they take after?
Is it okay that they love playing alone?
Why do they fixate on one thing?
Am I raising them well?
What will they grow to love?
Why are they so different from their sibling?

We don't just hand you a verdict. We show the work
Most personality apps give you a result and keep the reasoning to themselves. SoMyung shows you the calculation it was built from.
01
The eight characters, printed
All four pillars — year, month, day, hour — shown with their original Chinese characters. Check them against any other source you like.
02
The Five Elements, counted
How many of Wood, Fire, Earth, Metal and Water your child actually has. Not "an energetic kid" but "Fire 3, Water 0."
03
The method, stated
Traditional Manseryeok with true-solar-time correction for the birthplace. If the birth time is unknown, we say so and calculate from three pillars instead of four.
We would rather be checked than believed.
Creator of SoMyung · Parent of Three
I faced the same struggles
As a parent of three, I was always searching for better ways to understand and communicate with each of my children. After earning my Myeongri Psychology Counselor Level 1 certification and completing my Master of Science in Decision Analysis from Minerva University, I combined traditional Eastern wisdom with modern analytical thinking.
What worked for my first child didn't work for my second — because each has a different innate temperament. I built SoMyung so other parents could gain these same insights easily.

Frequently Asked Questions
Saju Myeongri is an Eastern philosophical system with thousands of years of history. SoMyung's analysis was designed by SungHa, a certified Myeongri Psychology Counselor (Level 1) who holds a Master of Science in Decision Making and Applied Analytics. The methodology combines traditional Myeongri studies with modern psychology — similar to how MBTI or the Enneagram provides a framework for understanding innate personality types, not predicting the future. SungHa developed SoMyung after applying this approach to raising three children and experiencing firsthand how understanding each child's temperament transformed family communication.
You can still get about 70% of the analysis without the birth time. Three pillars (year, month, day) are enough to identify core temperament and Five Elements balance. If you know the exact time, you'll get a more precise four-pillar analysis.
Use them as a reference for communication style, learning environment, and motivation. For example, a "Fire" temperament child benefits from short focus sessions and active learning. Remember, every child is unique — use this as a starting point, not an absolute guide.
Yes, results are generated within about 10 seconds after entering the birth date. The Manseryeok calculation and AI interpretation happen in real-time. You can view results on the web and share them with a link.
Absolutely. You can analyze siblings or other children anytime. Just click "Analyze Another Child" on the results page. Comparing different temperaments gives you even deeper insights.
We collect only the birth information needed to generate the analysis, plus — for paid reports — an email address and a name (or nickname) you choose to label the report. Free previews are not stored in our database. All data is encrypted in transit, and you can request deletion at any time. See our Privacy Policy for details.
The free first page shows the character that stands for your child and a first look at their temperament. The full letter (US$19.99) has six chapters: the light your child was born with (the eight characters and birth season), five ways your child meets the world, three everyday moments they get misread with a line to try in each, you and your child, this year and the next six months, and three small things to try this week with one sentence you can pass on to their teacher. It arrives by email with a PDF attached. Written to the standard of a certified Korean Saju practitioner, for a fraction of what one consultation costs.
