How To Read A Qi Men Dun Jia (QMDJ) Chart?

Posted On Last updated Nov 9, 2021 | Published on Oct 2, 2021

I’ve been getting a lot of requests for my input on how a Qi Men Dun Jia chart should be broken down and deciphered. I did briefly write about it a long time ago via this post but it was nothing too technical or in-depth. I was too distracted by the fact that I was having fun with it rather than giving a proper introduction on Qi Men Dun Jia. I decided to write a technical post on this that focuses on, well, the technical aspect of things.

This post does not aim to teach you everything you need to know about deciphering a chart but it lays down some of the basics and hopefully sets some standards in the field and stands out from all the other primers you can find elsewhere on the internet.

More importantly, this post is to bring everyone back onto the ground and remind everyone that Qi Men Dun Jia is not something you can easily pick up in a few weeks or months unless you’re telling me you’re proficient in BaZi, or you know the concepts of Yin Yang, 5 Elements, and the Stems and Branches like the back of your hand. There are a lot of courses out there right now given by practitioners who appeared out of nowhere, and to be honest, I’m concerned and appalled at the same time.

To put it simply, on top of serving as an introduction, this post is also to remind you that thinking you read from the internet or learned the self-declared master who appeared out of nowhere, is not enough.

Breaking Down The Qi Men Dun Jia Chart

Like any other Chinese astrological technique, most people get overwhelmed when they first lay their eyes on a Qi Men Dun Jia chart and the immediate thing they ask is “Where do I start?”.

First and foremost, you need to understand what makes up a Qi Men Dun Jia chart and the building blocks that form one. You’d always be looking at a 2D image when a chart is generated, but try to imagine several charts stacked on top of each other but confined within the 9 Sectors represented by the 8 Trigrams and a central sector (中宫)。The image below describes this very aptly:


A Qi Men Dun Chart consists of the following parts:

  • 神盘 or ‘Gods’ chart: This is part of the chart where you find the 8 ‘gods’ (八神) we use in Qi Men Dun Jia. Qi Men Dun Jia has a saying called 神助 in Qi Men Dun Jia and it refers to the influence of these 8 ‘gods’ it has in the chart.

  • 天盘 or ‘Heavens’ chart: This is where you find your 9 stars (九星) and they are the very same stars we use in feng shui and Zi Wei Dou Shu. These are the stars you find in the Big Dipper.

  • 人盘 or ‘Gates’ chart: Also called Doors by some practitioners but I prefer the word Gates. There are 8 in total and the Gates are used to represent humans.

  • 地盘 or ‘Earth’ chart: This is represented by your 8 Trigrams (八卦), within the 8 Trigrams are also your 12 Earthly Branches (十二地支) which will come in useful when analyzing a Qi Men Dun Jia chart.

  • 格局 or Sector Structure: Each sector in the Qi Men Dun Jia chart has s structure and this is formed by the Heavens chart Earth’s chart coming together. You will see two Heavenly Stems (十天干) in every sector, with one resting on top of another. All Heavenly Stems are used with the exception of Yang Wood (甲木) and it can be paired in any way but note that if the Stems in the Heavens Chart and Earth chart are flipped, it’s considered a different structure. For example, 辛 sitting on 乙 has a different meaning from 乙 sitting on 辛。

  • 盘外格局 or External Structure: This is actually just referring to the BaZi chart or Four Pillars that were used to generate the Qi Men Dun Jia chart. BaZi or Four Pillars is a forecasting technique on its own, but please do not forget that it’s still a time-keeping system at its core which is why you’ll always see it in other Chinese astrology techniques. We can use the BaZi chart that’s reflecting the time on the Qi Men chart to derive useful information.

Now, imagine the different parts of the charts stacked on top of each other and this is what you get:

What you’re looking at is supposed to be 3D but is presented in a 2D format which is actually fine. There’s no need for the chart to be a 3D chart to do what it’s supposed to do if you understand its building blocks of it.

How Is Qi Men Dun Jia Used?

Newcomers to Qi Men Dun Jia don’t actually know what this technique does because how it is applied is very different from BaZi and Qi Men Dun Jia.

As confounding as it sounds, Qi Men Dun Jia is no different from going to a temple to cast a divination lot (求签) or getting a tarot card reading. If you have a question in your mind, ask it, and the universe gives you a response. Qi Men Dun Jia is basically the Chinese version of divination, with tarot cards and horary astrology of Western astrology as some of its counterparts. Note that Qi Men Dun Jia is not the only Chinese divination method available – there is also 六壬 and 太乙。

One core concept in Qi Men Dun Jia is what we call 万物相干论, which is basically the interconnection of everything. In modern-day science, we give it a different name, like the Theory of Everything or the Superstring Theory. The Chinese sages explored the same concept, but could only express it in a way relevant to that era. Speaking of which, I’ve always found it perplexing how sceptics dismiss Chinese metaphysics so easily but do not do the same for modern-day physics.

The Qi Men Dun Jia chart is a snapshot in time and what most people forget is that we and our lives are also part of this snapshot of time while sharing an interconnection with everything else, which is why whenever you generate a Qi Men Dun Jia chart with a sincere question in mind, it tends to really speak to you provided you know how to interpret the charts.

Divination techniques required a great amount of focus, with the heart and mind in the right place because if you’re casting a divination or asking a question that you have no intention of acting on, then it’s not meant to happen and the chart will not speak to you.

To put it simply, using Qi Men Dun Jia is really just about:

  • Asking a question
  • Interpreting the chart
  • Decide what’s the next action to take

I used to go to the temple to cast a divination lot in the past because that was the only divination method that laypeople have access to, but Qi Men Dun Jia can be done anywhere.

Different Types Of Qi Men Dun Jia

When I say different “types” of Qi Men Dun Jia, it’s not referring to a different technique of interpretation. It refers to a different method of plotting the chart. There are different types:

  • 刻家奇门
  • 时家奇门
  • 月家奇门
  • 年家奇门
  • 金涵奇门

The core difference between the various methods of plotting the chart is that the possible number of chart permutations are different and the timeframe we use to interpret the charts are also different which is why you’ll see 年,月,日,时 which refers to Year, Month, Day, and Hour.

People usually use is 时家奇门 as it has the most number of chart permutations, with 4320 different charts but each chart will repeat itself four times, so there are actually 1080 unique charts in the Hour-Version of Qi Men Dun Jia (时家奇门)。金涵奇门 is unique due to its history, and it is the version of Qi Men Dun Jia used by Zhang Liang (张良) and Zhu Ge Lian (诸葛亮)。

There are a few other technical aspects that are important to understand that involve the plotting of the Qi Men Dun Jia chart although most hobbyists and even new ‘practitioners’ would not bother with it. Any form of divination or astrological technique requires precise calculations of the planets and where Earth is and it’s no different for Qi Men Dun Jia.

You would hear of terms like 置润,拆补, and 茅山 that some newly-minted practitioners would label “different techniques” of Qi Men Dun Jia but it is not. These are terms used to adjust for the marginal errors that are intrinsic during the process of plotting a Qi Men Dun Jia chart. Qi Men Dun Jia uses the Solar Terms (节气) just like how BaZi does, and the Solar Terms change approximately every 15 days the keyword here is “approximate” because the actual time it takes is 15.2184 on average so there is bound to be some errors the longer time stretches. 置润,拆补,茅山 are just terms used by different schools to make adjustments, it does not change the way a chart is interpreted but the way they are plotted.

Lastly, let’s also not forget that Qi Men Dun Jia also differentiates between Rotating Charts (转盘) and Flying Charts (飞盘). Almost all Qi Men Dun Jia charts are interpreted using Rotating Charts these days and Flying Charts aren’t used except for during special situations. Rotating Charts are used to assess the macro-environment in relation to the people involved in the divination whereas Flying Charts are focused more on human issues and dynamics and less on the environment.

Where To Begin In Interpreting A Qi Men Dun Jia Chart?

You will always hear the term ‘Yong Shen’ (用神) in Chinese metaphysics. It will mean different things in different Chinese astrological techniques. In BaZi, it refers to the critical element the chart needs for it to be balanced. In Zi Wei Dou Shu, it refers to the Four Transformer stars (四化).

In Qi Men Dun Jia, ‘Yong Shen’ basically refers to the part of the chart where you find your answer and there can be more than one ‘Yong Shen’ in this case. Where you find your answer, of course, depends on what kind of question you’re asking. For example:

  • If someone comes to me for a Qi Men Dun Jia divination regarding relationships, the ‘Yong Shen’ in this would be Yang Metal (庚) representing the male, and Yin Wood (乙) representing the female. Their Year Stems can also be used.

  • If it’s about money, we look at Yang Earth (戊) and Gate Of Life (生门) as these symbolize these aspects of life.

Everything we experience in the physical world can be symbolized by something you see in the Qi Men Dun Jia chart. One might ask why is it that a mere 5 Elements, 10 Heavenly Stems, and 12 Earthly Branches possibly represent every single thing in the world. This is where one really needs to go back in history and understand Yin Yang and Chinese cosmology, and the notion of 取象。

The common practice when looking for the answer is to look at the Hour Stem when the chart is generated, but it’s not always the case. Once we know where to look in the Qi Men Dun Jia chart, that’s when we can start going in-depth and find out what will happen because merely knowing where the symbols representing your answer lie is not enough.

What Can Qi Men Dun Jia Predict And What It Is Used For?

A lot of people shy away from Qi Men Dun Jia because they don’t understand what Qi Men Dun Jia can be applied for. To keep things simple, we can just say Qi Men Dun Jia can be applied to “everything” because its principles and laws are based on 万物相干论 where everything is interconnected. Of course, you don’t apply it for trivial matters like what should you eat for dinner although it’s still possible.

The point is that the bigger and more important the event, the stronger and more salient the manifestation it has on Earth. The chart will speak to you more if it is something important to you, which is why casting a divination was a very important ritual in feudal China.

Some of the common uses of Qi Men Dun Jia and what it can be used for are:

  • Predicting the weather
  • Marriage and relationships
  • Health, Pregnancy
  • Outcome of exams
  • Career changes
  • Finding a lost item
  • Hunting for a culprit
  • Business and investment decisions
  • Assessing feng shui
  • Travel and safety

For every different event, the ‘Yong Shen’ (用神) and what you need to look out for will be different. You will need to where to look for in the chart and then proceed to analyze the combined meaning behind the Gods, Gates, Sectors, and Stars.

The ‘Story’ Behind The Qi Men Dun Jia Chart

I am not going to attempt to explain how a Qi Men Dun Jia is interpreted because this is a complex technique that is being misconstrued as something that anyone can do. I can understand why people might feel that this is an easy technique to pick up, but the lack of fundamental knowledge in Chinese metaphysics does lead to a lot of wrong interpretations. I’ll just use this segment to talk about what the Qi Men Dun Jia chart is trying to convey.

The Qi Men Dun Jia chart is like a snapshot in time and to be fair, any astrological chart you read is a snapshot in time. The point is to know what this snapshot in time is telling you and what will happen on Earth based on the information you get from it.

Every part of the chart comes together to paint a story of the current situation and how it will unfold. The ‘Gods’, Stars, Gates, and Heavenly Stem structure are all symbols of something, and different symbols coming together will mean different things. The position of these symbols also alters their meaning, and even seasons also alter the meaning. If you wanted to, you can even bring in BaZi techniques into Qi Men Dun Jia.

What you see might be a static 2D image of the chart, but when you should really be seeing is how different parts of the chart are interacting with each other and the flow within the chart.

As you can tell, interpreting a Qi Men Dun Jia chart might look simple on the surface, but it is not and there is a lot of depth to it.

Advanced Theories Of Qi Men Dun Jia

I am very insulated from what is being taught out there by the commercial world, but from what I know, it’s been dumbed down in order to sell it to the masses. Most people only apply this logic when interpreting a Qi Men Dun Jia chart:

“If the sector representing the answer gives birth to the sector representing me, it’s favourable to take action.”

If that were the case, there’s really no need to look at anything else but the Earth chart and we can just make our deductions using the 8 Trigrams. Qi Men Dun Jia just because about looking at 8 different boxes and seeing whether the two relevant ones happen to be in favour of each other.

The requirements needed to be proficient at Qi Men Dun Jia are no different from BaZi. You need to understand the Heavenly Stems, Earthly Branches, and the technicalities of it. As mentioned in the previous section, where the Gods, Gates, Stems land in the chart will change its meaning. The seasons and Four Pillars generated will also change their meaning.

There are a few advanced theories that you really need to understand before you can even begin interpreting a Qi Men Dun Jia chart, and I would not encourage anyone to try interpreting charts until they fully understand these concepts:

  • 击刑
  • 空亡
  • 入墓
  • 入库
  • 旺衰

Please do not forget that the above are all related to the ‘Gods’, Stars, Gates, and Stems.

Should You Learn Qi Men Dun Jia?

Well, that’s up to you and I will refrain from commenting too much here because my blog would have already addressed topics like this.

The only thing I wish to say is that not everyone is meant to study this and most people can’t differentiate being curious about something and truly having an affinity with it and this applies to everyone – prospective students and prospective practitioners alike.

One more issue I wish to point out is that we’re in an era where anyone can just appear out of nowhere, declare themselves as a practitioner or master, and start giving BaZi or Qi Men Dun Jia consultations.

Please just be careful with who you approach to get a reading from, and more importantly who you learn from. If you believe in Chinese metaphysics and how it’s still relevant, and you believe in what Qi Men Dun Jia can do and how it can forecast outcomes and describe how phenomenon manifests, then it makes sense to believe that many people end up approaching the wrong kind of ‘practitioner’ simply because it’s written in the stars.
