Chinese skyscrapers often skip the 4th floor, while apartments numbered 8 sell at a premium. That's not superstition out of nowhere — behind it is a thousand-year-old system of correspondences between numbers and the five elements, Wu Xing (五行 (wǔ xíng — "five elements")). 🔢 But here's what 99% of people miss: there is no such thing as a universally "lucky" number. The number 8 really does carry the energy of Earth, and 4 the energy of Wood, but whether they work for you depends on which elements your personal BaZi chart needs.
In this article we'll cover where the link between numbers and elements even comes from (the Lo Shu magic square), how the digits are distributed across the five elements, how to work out your own numbers through the concept of Yong Shen (用神 (yòng shén — "Useful God")), which numbers work for money and which for career and health, what to avoid, and how to apply all of this to your phone, apartment number, PIN code and choice of dates. And why the myth "4 always means death" is a dangerous oversimplification.
1 Where the link between numbers and elements comes from — Lo Shu and He Tu
The roots of the number system lie in two ancient diagrams of Chinese metaphysics, together known as 河圖洛書 (hé tú luò shū — "the River Map [of the He] and the Writings [of the Lo]"). Legend says that on the back of a dragon-horse emerging from the Yellow River (河, hé — "the Yellow River"), Emperor Fu Xi saw a pattern of dots — this was the He Tu (河圖 (hé tú — "river map")). And on the shell of a divine turtle from the Luo River appeared a magic square — the Lo Shu (洛書 (luò shū — "writings of the Luo River")).
The Lo Shu is a 3×3 grid where the numbers 1 through 9 are arranged so that every row, column and diagonal adds up to 15. It's the oldest known magic square:
Every cell of the square is also a compass direction and an element. The center (number 5) is Earth, the fulcrum. North (1) is Water, south (9) is Fire, east (3) is Wood, west (7) is Metal. It's the Lo Shu that gave rise to both "flying star" feng shui (玄空飛星, xuán kōng fēi xīng — "mysterious void, flying stars") and the number numerology we use today.
2 The numbers of the five elements — the basic table
From the He Tu comes the most practical correspondence — how the ten digits (including 0) are distributed across the five elements. The digits come in pairs: one "yang," one "yin," and each pair belongs to one element.
There's a nuance worth spelling out here. In the classical He Tu the pairs are: 1·6 — Water 水 (shuǐ — "water"), 2·7 — Fire 火 (huǒ — "fire"), 3·8 — Wood 木 (mù — "wood"), 4·9 — Metal 金 (jīn — "metal"), 5·10(0) — Earth 土 (tǔ — "earth"). Odd numbers (1, 3, 5, 7, 9) are considered yang (陽, yáng — "bright"), even numbers (2, 4, 6, 8, 0) are yin (陰, yīn — "dark").
3 How to find YOUR numbers — through Yong Shen
Now for the most important part. For a number to bring luck to you, it needs to carry the element of your Yong Shen (用神 (yòng shén — "Useful God")) — the element that balances your chart and "heals" its imbalance. This is the central concept of the Ziping school (子平派, zǐ píng pài — "the Ziping school"), and without it any numerology turns into guesswork.
The logic is simple. First, the strength of the Day Master (日主 (rì zhǔ — "master of the day")) — the Heavenly Stem of your birth day — is determined from your chart. If it's too strong, it needs elements that drain it; if it's too weak, it needs elements that nourish it. That "healing" element is your Yong Shen. The numbers that carry it are your lucky numbers.
The algorithm in three moves:
- Calculate your BaZi chart and find your Yong Shen (say, Fire).
- Find the numbers of that element in the table above (Fire = 2 and 7).
- Add the numbers of the "nourishing" element (Xi Shen, 喜神 (xǐ shén — "happy god")): for Fire that's Wood (fuel) — 3 and 8.
That gives you your personal set. If your Yong Shen is Fire, your main lucky numbers are 2, 7, with 3, 8 as support. If your Yong Shen is Water, your numbers are 1, 6, plus the "mother" element Metal — 4, 9.
| Your Yong Shen | Main numbers | Support (Xi Shen) |
|---|---|---|
| Wood 木 | 3 · 8 | 1 · 6 (Water nourishes) |
| Fire 火 | 2 · 7 | 3 · 8 (Wood nourishes) |
| Earth 土 | 5 · 0 | 2 · 7 (Fire nourishes) |
| Metal 金 | 4 · 9 | 5 · 0 (Earth nourishes) |
| Water 水 | 1 · 6 | 4 · 9 (Metal nourishes) |

Yong Shen gives you "general" luck. But if you need to target a specific area, the system of ten gods (十神 (shí shén — "ten gods")) comes into play — the ten roles the elements play relative to your Day Master. Money, career and health are each governed by different "gods," and so by different elements and different numbers.
💰 Numbers for money
Wealth is governed by the Wealth element (財 (cái — "wealth")) — the element your Day Master controls. For a Wood Day Master, for instance, money is Earth (Wood holds Earth with its roots), so the "money" numbers are 5 and 0. For a Fire Day Master, money is Metal (Fire melts Metal), and the numbers are 4 and 9.
📈 Numbers for career and status
Career, position and authority come from the Officer element (官 (guān — "officer, authority")) — the element that controls your Day Master. For Wood that's Metal (Metal chops Wood) — numbers 4 and 9. For Water that's Earth (Earth contains Water) — numbers 5 and 0.
🌿 Numbers for health
Health depends on the balance of the Day Master itself. If it's weak, health is helped by the numbers of the Resource element (印 (yìn — "seal, resource")) — the "mother" element that nourishes you — plus the numbers of your own element. If the Day Master is strong, the opposite is true — numbers that gently drain it.
5 What to avoid — numbers of the "harmful" element
Just as every chart has a Yong Shen, it also has a Ji Shen (忌神 (jì shén — "forbidden god")) — the element that worsens the imbalance and does harm. The numbers of that element are your "unlucky" numbers, worth avoiding in important contexts.
The logic mirrors section 3. If your Yong Shen is Fire (numbers 2, 7), your Ji Shen is most often Water (numbers 1, 6), because Water puts out Fire. If your Yong Shen is Wood (3, 8), your Ji Shen is Metal (4, 9), which chops Wood.
| If Yong Shen is | Avoid these numbers | The harming element |
|---|---|---|
| Wood 木 | 4 · 9 | Metal (chops Wood) |
| Fire 火 | 1 · 6 | Water (puts out Fire) |
| Earth 土 | 3 · 8 | Wood (exhausts Earth) |
| Metal 金 | 2 · 7 | Fire (melts Metal) |
| Water 水 | 5 · 0 | Earth (absorbs Water) |
6 Putting it to use — phone, apartment, car, PIN, dates
Theory without practice is dead. Here's where numbers actually work in daily life. The principle is one and the same: in the places you use often and that are "yours," stack up Yong Shen numbers.
How to work out a multi-digit number. Take all the digits, add them down to a single digit (numerological reduction), and look at its element. Example: a phone ending in …3782 → 3+7+8+2 = 20 → 2+0 = 2 → element Fire. If your Yong Shen is Fire, that's a great number. A simpler, rougher method is to just look at which digit appears most often in the number.
7 The link to Heavenly Stems and Earthly Branches
There's a second, more "structural" layer of numbers — the ordinal numbers of the ten Heavenly Stems (天干 (tiān gān — "heavenly stems")) and the twelve Earthly Branches (地支 (dì zhī — "earthly branches")). These 22 signs are the alphabet of BaZi, and each has its own ordinal number, which also carries numeric energy.
| No. | Stem | Element | No. | Stem | Element |
|---|---|---|---|---|---|
| 1 | 甲 Jia (jiǎ) | Yang Wood | 6 | 己 Ji (jǐ) | Yin Earth |
| 2 | 乙 Yi (yǐ) | Yin Wood | 7 | 庚 Geng (gēng) | Yang Metal |
| 3 | 丙 Bing (bǐng) | Yang Fire | 8 | 辛 Xin (xīn) | Yin Metal |
| 4 | 丁 Ding (dīng) | Yin Fire | 9 | 壬 Ren (rén) | Yang Water |
| 5 | 戊 Wu (wù) | Yang Earth | 10 | 癸 Gui (guǐ) | Yin Water |
Likewise, the twelve Earthly Branches are numbered 1 through 12: 子 (zǐ — "Rat", No.1, Water), 丑 (chǒu — "Ox", No.2, Earth), 寅 (yín — "Tiger", No.3, Wood), and so on up to 亥 (hài — "Pig", No.12, Water). When a practitioner sees that your Yong Shen is Fire, they know: you resonate not only with the numbers 2 and 7 (via He Tu), but also with the ordinal numbers of the fire signs — stems No.3 (Bing) and No.4 (Ding).
For everyday use, the basic table in section 2 is enough. But the ordinal numbers of the stems and branches explain why practitioners sometimes name "non-standard" personal numbers — they're looking deeper, at the exact signs in your chart, not just at the general element.
8 Myths — "8 always means wealth, 4 always means death"
The most persistent myth in Chinese numerology was born from Cantonese phonetics, not metaphysics at all. The number 8 (八 (bā — "eight")) sounds in Cantonese like 發 (fā — "to prosper, to get rich"), hence "8 = money." And 4 (四 (sì — "four")) sounds like 死 (sǐ — "death"), hence "4 = death."
That's a linguistic association, not an elemental one. From a BaZi standpoint:
- 8 carries the element of Wood (via He Tu, the pair 3·8). If your Yong Shen is Metal, then 8 is more likely unfavorable for you, because Metal chops Wood, spending its strength. There's no "guaranteed money."
- 4 carries the element of Metal (the pair 4·9). If your Yong Shen is Metal or Water, then 4 is a lucky number for you — regardless of its "ominous" sound.
Another popular myth is "the more eights the better." Too much of one element is just as harmful as too little. The number 8888 for someone with Metal as their Yong Shen is an overdose of Wood, which Metal is then forced to endlessly chop away at. Balance matters more than quantity.
9 Your personal lucky date — how to pick a favorable day
Choosing dates is already 擇日 (zé rì — "date selection"), a separate art within Chinese metaphysics. But the basic principle, built on numbers and elements, is available to everyone.
Every day in the Chinese calendar has its own pillar — a Heavenly Stem plus an Earthly Branch, and so its own element. A good day for an important task is one whose element:
- Carries your Yong Shen — the main criterion. A Fire-element day for someone with Fire as their Yong Shen is a tailwind.
- Doesn't clash with your year/day sign — avoid days whose branch is in "clash" (冲, chōng — "clash") with yours.
- Fits the nature of the task — a Wealth-element day is good for money, and for a wedding, a day that's harmonious for both partners.
For truly important events (a wedding, a business launch, surgery), it's worth ordering a personal date selection — that takes into account not just numbers, but clashes, "day breakers," and the elemental compatibility of everyone involved. Numbers give you a first approximation; a practitioner gives you the exact date.
10 Practice — build your own set in 3 steps
Let's bring it all together. Here's a step-by-step recipe for getting your personal set of lucky numbers today. 🎯
Step 1. Find your Yong Shen
Calculate your BaZi chart (you'll need your date, time and place of birth). Find your Day Master's strength and your useful element — Yong Shen. This is the foundation: without it, any set of numbers is "generic," not "yours."
Step 2. Write down your main and support numbers
Using the table from section 3: the numbers of your Yong Shen (main) plus the numbers of Xi Shen, the "mother" element (support). For example, Yong Shen Water → main numbers 1, 6; Xi Shen Metal → support numbers 4, 9. Your base set: 1, 4, 6, 9.
Step 3. Add "targeted" numbers and drop the "harmful" ones
Want to boost money? Add the Wealth numbers (section 4). Career? Add the Officer numbers. And drop the Ji Shen numbers from your priorities (section 5). You'll end up with a final personal list of 3–5 digits that you deliberately choose in your phone, PIN, dates and plate numbers.
And remember the main thing: numbers are a fine adjustment, not a lever on your fate. They work like a tailwind — they don't replace effort, but they make the going a little easier. The real power comes from understanding your entire chart — your Day Master, Yong Shen, luck pillars and ten gods. Numbers are just one tool of applied BaZi. 🌟
