BaZi vs MBTI: An Ordinary Person Tries Both Systems

At a friend's dinner, someone suddenly asked, "What's your MBTI?"

The whole table started calling out answers. INFP, ENTJ, ISFJ... like reciting a new kind of code. I was the only one who didn't know mine. They made me take a test, and the result came back — INTP. Someone nodded and said "that makes sense," another said "really? I wouldn't have guessed."

I thought, so in other people's eyes, I can be summed up by four letters.

Walking home that night, I kept thinking about it. Not that I was upset — more that I found it fascinating. We want so badly to know "what kind of person am I?" Humanity has invented so many ways to answer this one question.

Ancient Greece had four temperaments: sanguine, choleric, melancholic, phlegmatic. Modern times gave us MBTI, the Big Five, the Enneagram. And my ancestors had their own system — it's called BaZi.

My mom used to say, "You were born in the Year of the Ox, of course you're stubborn"

Honestly, my first encounter with "fortune-telling" wasn't at a temple. It was at the dinner table.

Growing up, every Lunar New Year when visiting relatives, some aunt or uncle would say, "This kid was born in the Year of the Ox — definitely stubborn." Or "Year of the Monkey, clever one." I thought the adults were just saying things, like how you'd coax a child. Only later did I learn there was an entire system behind it — zodiac animals, five elements, heavenly stems and earthly branches. Combined together, that's BaZi.

What is BaZi? Simply put, it's your year, month, day, and hour of birth expressed in the language of stems and branches — eight characters in total. For example, if you were born on May 15, 1990 at 3 PM, it might translate to something like "Geng-Wu, Xin-Si, Jia-Zi, Ren-Shen." These eight characters contain the distribution of metal, wood, water, fire, and earth, along with the balance of yin and yang. And supposedly, from this, you can read a person's temperament, fortune, and health.

I used to think it was superstition.

Then I actually read a few books on BaZi

About two years ago, I was going through a rough patch. Work wasn't going well, my relationship was a mess, and I couldn't quite articulate what was wrong — just that everything felt blocked. A friend recommended a BaZi reader, so I went.

He wasn't wearing a Daoist robe. Just an ordinary man in his fifties, with a cup of tea on his desk. He looked at my birth information, laid out a chart, and said a few things. Some of them were so accurate — I felt a chill down my spine. Others I didn't quite agree with. The whole thing lasted about forty minutes. He never said "you are destined to..." Instead, he talked about "tendencies in your temperament, and how they'll play out differently in different years."

I went home and bought two books — one was Yuanhai Ziping, a Song dynasty classic, the other a modern introduction to BaZi. I read them on and off for a year. I wouldn't claim to understand it, but at least I got the gist of what BaZi is trying to say.

It's not saying "this is what you're doomed to be." It's saying "these are the qualities you were born with."

And that's exactly what MBTI is doing too.

One uses letters, the other uses elements

MBTI describes a person along four dimensions: introvert or extrovert (I/E), sensing or intuition (S/N), thinking or feeling (T/F), judging or perceiving (J/P). Then it sorts you into one of sixteen types.

BaZi? It uses heavenly stems, earthly branches, yin-yang, and the five elements. If your chart has a lot of Wood, it suggests you're kind-hearted and principled but possibly stubborn. A lot of Fire means courteous and passionate but prone to impatience. Metal — resolute and loyal but sometimes too blunt. Water — clever and adaptable but sometimes fickle. Earth — trustworthy and steady but sometimes overly conservative.

Notice something? Both are using symbols to summarize personality.

MBTI divides people into 16 types. BaZi, theoretically, has over a million combinations (60 years × 12 months × 60 days × 12 hours, multiplied by different "life phases" for men and women) — far more nuanced than 16 categories.

But they're addressing the same question: Who am I? Why am I the way I am?

Is it accurate?

That's what everyone wants to know.

MBTI has a known issue — many people get different results when they take the test twice. I'm in a good mood today and score as an E; I'm feeling down next week and score as an I. That's why the academic psychology community doesn't fully endorse MBTI — they say the reliability isn't there. But MBTI's popularity proves that people don't care about reliability. What they care about is being understood. When you read the description of your type and feel that "aha" moment — that feeling itself is healing.

BaZi? Its biggest problem is that you can't verify its accuracy, because it doesn't lend itself to double-blind experiments. The same chart can be interpreted differently by different practitioners. One says you have strong wealth luck; another says your wealth element overwhelms your personal element and you can't hold onto it. Who's right?

But I think that question itself is missing the point.

Whether it's MBTI or BaZi, neither is performing precise scientific measurement. They're mirrors. You can't ask a mirror "are you accurate?" A mirror just shows you one angle of yourself.

The interesting thing is, some angles are ones you can't see on your own.

Two systems, two different flavors

They're solving the same problem, but MBTI and BaZi feel completely different.

MBTI is static. You take the test, get a type, and that's you. Many people carry this label for years, even turning it into an identity — "I'm an INTJ, so I'm not good at socializing." Sometimes this label is an explanation; sometimes it becomes a limitation.

BaZi is dynamic. It doesn't just look at your "birth chart" — it also looks at your "major life phases" (Da Yun). Every ten years, you enter a new phase, and different phases bring different circumstances. The same person at twenty and at forty can be completely different. BaZi keeps emphasizing timing — it's not that you're not capable, it's that the right moment hasn't arrived yet.

I love this about it.

Western personality tests tell you "this is who you are," as if your personality is fixed at twenty. BaZi tells you "this is the season of life you're in." It acknowledges change. It acknowledges flow. This year, everything feels like it's going wrong — maybe it's not you. Maybe you're just in a transitional period.

This reminds me of something.

The last thing the BaZi reader said

When I was leaving that session, I asked him, "So do you think I should change jobs?"

He smiled and said, "With your chart, nothing goes very smoothly before thirty. Thirty to forty, things will be much better. But what exactly you should do — that's not for me to decide. A chart can only tell you the weather. Walking the road is still up to you."

And indeed, after I turned thirty, many things did get better. Maybe it was luck. Maybe it was years of accumulation finally paying off. Maybe it was just psychological suggestion. But that sentence stayed with me — a chart can only tell you the weather. Walking the road is still up to you.

I think that's good advice for anyone who just got their MBTI results too.

Your type can't make decisions for you. Knowing you're an INFP doesn't mean you should give up on logical thinking. Knowing you were born in the Year of the Ox doesn't mean you have to be stubborn forever. These systems are tools, not verdicts. Their purpose isn't to stick a label on you — it's to give you a mirror, a chance to see your own blind spots.

How I see it now

I did the MBTI, and I found it interesting. I also looked into BaZi, and I found that interesting too. But I don't plan on locking myself into either system.

Sometimes I think the reason we're all so drawn to personality tests, horoscopes, BaZi, tarot... is fundamentally because humans share a common confusion — we don't understand ourselves.

You've lived with yourself your whole life, yet some things remain invisible to you. It's like how your eyes can see the whole world but can never see your own face. That's why we need mirrors — MBTI is one mirror, BaZi is another, and a friend's honest words are a mirror too.

You can look in a mirror. Just don't mistake the mirror for yourself.

What about you? Have you ever taken a personality test? Was there one that made you feel "seen"?

Do you believe in BaZi or horoscopes? Or do you think it's all the Barnum effect?

If there were a mirror that could tell you, with 100% certainty, who you are — would you really want to look?
