The Later Heaven Bagua: The Dynamic Map of Your Life & Home
The Later Heaven Bagua (後天八卦, Hòutiān Bāguà), also known as the “Post-Celestial” or “King Wen” Bagua, is the single most important map used in practical Feng Shui. While the Early Heaven Bagua shows the “ideal” state of the universe, the Later Heaven Bagua shows the world as we experience it: a dynamic, cyclical, and ever-changing flow of energy.
This is the arrangement that connects the Eight Trigrams to the seasons, the compass directions, and the flow of time. When you analyze a home, apply cures, or use any practical Feng Shui calculator, you are using the logic of the Later Heaven Bagua.
In this guide, we’ll explore the origin of this powerful map and how it became the foundation for nearly all modern Feng Shui schools.
The creation of this Bagua is attributed to King Wen (Ji Chang) around 1150 BC. The legend states that a turtle emerged from the Luo River after a great flood, bearing a divine 3×3 grid pattern on its shell. This pattern, where every row, column, and diagonal added up to 15, is known as the Lo Shu (Luo River Writing).
King Wen arranged the Eight Trigrams around this Lo Shu square, creating a dynamic map that represented the flow of energy through time and the seasons. This arrangement is not one of ‘perfect opposites’ like the Early Heaven; it is a map of cyclical progression.

The Structure of Cyclical Change (The Lo Shu Map)
The Later Heaven Bagua is essentially the Lo Shu magic square brought to life. Each trigram is assigned to a number and a compass palace, representing the flow of the seasons on Earth.
This is the arrangement you must know for all practical Feng Shui:
- ☲ Li (Fire) is at the South (Lo Shu 9): The peak of summer and daylight. Represents fame and clarity.
- ☵ Kan (Water) is at the North (Lo Shu 1): The depth of winter and midnight. Represents career and life path.
- ☳ Zhen (Thunder) is at the East (Lo Shu 3): The start of Spring and sunrise. Represents family and new beginnings.
- ☱ Dui (Lake) is at the West (Lo Shu 7): The middle of Autumn and sunset. Represents joy and children.
- ☴ Xun (Wind) is at the Southeast (Lo Shu 4): Late spring/early summer. Represents wealth and growth.
- ☷ Kun (Earth) is at the Southwest (Lo Shu 2): Late summer/harvest. Represents marriage and motherhood.
- ☶ Gen (Mountain) is at the Northeast (Lo Shu 8): Late winter/early spring. Represents knowledge and stillness.
- ☰ Qian (Heaven) is at the Northwest (Lo Shu 6): Late autumn/early winter. Represents mentors and the patriarch.
Early Heaven vs. Later Heaven Bagua: The Critical Difference
To master Feng Shui, you must know when to use each map. They are not interchangeable, but work together as “Essence” and “Application.”
| Attribute | Early Heaven Bagua (Ideal) | Later Heaven Bagua (Practical) |
|---|---|---|
| Concept | “Pre-Manifestation,” “Essence,” “Why” | “Post-Manifestation,” “Application,” “How” |
| State | Static, balanced, unchanging. | Dynamic, cyclical, changing with time. |
| Primary Use | Philosophy, I Ching, understanding Trigram essence. | This is the map used for Yang Zhai (Home Feng Shui), Flying Stars, and 8 Mansions. |
The Foundation of All Practical Feng Shui
When you use any of the calculators on this site, you are using the Later Heaven Bagua. Its structure is the foundation for the most powerful Feng Shui systems used today:
- Flying Stars (Xuan Kong): The entire Flying Stars system is based on the 9 numbers of the Lo Shu square and their corresponding trigrams and elements. The Natal Chart maps how these time-based energies are “locked” into your home.
- Eight Mansions (Ba Zhai): This system uses the Later Heaven Bagua to divide a house into 8 sectors and determine the 4 “favorable” and 4 “unfavorable” directions based on a person’s Gua number.
- Practical Applications: When you overlay a Bagua map on your floor plan using the compass method, you are using the Later Heaven Bagua directions (South = Fire/Fame, North = Water/Career, etc.)
Conclusion: The Map of Your Life
Think of the Early Heaven Bagua as the “factory blueprint” for energy. The Later Heaven Bagua is the “owner’s manual” for the finished product—the world we live in.
It is the map of change, the seasons, and the cyclical nature of life. By understanding this map, you gain the power to read the energy of any space and, most importantly, you learn how to balance it using the Five Elements to create harmony, health, and prosperity.
Frequently Asked Questions
The Later Heaven (Post-Celestial/King Wen) Bagua connects the Eight Trigrams to compass directions, the seasons and the flow of time, so it reflects the dynamic world we actually live in. Because of this, it is the arrangement behind practical Feng Shui — reading a floor plan, placing cures, and running every major Feng Shui calculator.
King Wen arranged the Eight Trigrams around the Lo Shu (Luo River Writing) square, creating a dynamic map of cyclical progression rather than the perfect opposites of the Early Heaven. The Lo Shu numbers (1–9) sit behind the nine sectors, tying the trigrams to the seasonal flow of energy.
The Early Heaven (Fu Xi) shows the ideal, static universe of perfect balance — the “factory blueprint” of creation. The Later Heaven (King Wen) is the “owner’s manual” for the finished product: a dynamic map of change, seasons and cyclical energy. For anything practical — your home, your office, cures, calculators — you use the Later Heaven arrangement.
Most practical schools rest on the Later Heaven arrangement: the Flying Stars (Xuan Kong) system, the Eight Mansions (Ba Zhai), the Bagua Map, and the compass direction analysis of the 24 Mountains. If a method maps energy onto a floor plan by direction, it is almost certainly using the Later Heaven logic.
In the Later Heaven arrangement each trigram is fixed to a compass direction: Zhen (East), Xun (Southeast), Li (South, Fire – Fame), Kun (Southwest), Dui (West), Qian (Northwest), Kan (North, Water – Career), and Gen (Northeast). The Lo Shu numbers and Five Element seasons follow this same directional cycle.
