Luantou Four Qi Explained: On-Site Identification of Sheng Qi, Si Qi, Yang Qi, and Yin Qi — Judge Qi Quality With Your Eyes, Nose, and Skin When Buying a Home

The Luantou School reads qi before anything else. Four types of qi: Sheng Qi (vegetation glossy, soil lustrous, air sweet — livable), Si Qi (vegetation withered, soil dark, air fishy-rotten — inauspicious, uninhabitable), Yang Qi (dry and hot, sparse vegetation, restless energy field — needs yin supplementation), Yin Qi (cold and damp, moss-covered, oppressive energy field — needs yang supplementation). On-site characteristics, identification formulas, and practical house-buying operations for all four qi types. Learn to read vegetation with your eyes, smell the air with your nose, and sense temperature with your skin — three lines of defense to filter out inauspicious properties.

The Luantou School Doesn't Look at Direction First. It Looks at Qi First. If the Qi Is Wrong, the Most Precise Compass Is Useless.

You go to view a house. The agent talks about the floor plan, the orientation, the floor-area ratio. The first thing a Luantou School feng shui master does upon entering — feel the qi of the place. Whether the qi is right, you know in three minutes. Everything else is detail.

One of the most core theories of the Luantou School: the land has Sheng Qi and Si Qi. Where Sheng Qi gathers, vegetation is lush, soil color is lustrous — living there, your spirit thrives. Where Si Qi gathers, vegetation is withered, soil color is dark — living there, you wither and fall ill. The Four Qi theory comes from the Zang Jing — Guo Pu wrote: "Qi resonates and responds. The fortune of the dead reaches the living." Qi is alive. Sheng Qi nourishes people. Si Qi harms people. Yin and Yang Qi sit in between — too much yang and it's parched. Too much yin and it's damp. The on-site judgment methods for the four qi types: ancient feng shui masters relied on their feet, eyes, nose, and hands. Today, you view a house exactly the same way — no compass, no Bazi. Just bring your eyes, nose, and skin. This article paints a picture of the four qi types for you. What Sheng Qi looks like. What Si Qi smells like. How to harmonize Yang Qi and Yin Qi. After reading, you can screen houses yourself.

Four Qi rapid assessment formula: ① Sheng Qi — grass green, soil moist. The air carries a sweet scent. You walk in and breathe smoothly. You don't want to leave. ② Si Qi — grass yellow, soil black. The air smells fishy, rotten, or moldy. You walk in and your chest tightens. You want to leave. ③ Excessive Yang Qi — dry and parched. Grass sparse, leaves scorched. You walk in and feel restless. Can't sit still. ④ Excessive Yin Qi — damp and cold. Moss climbs the walls. You walk in and your shoulders tighten. Your body wants to curl up. When house hunting — first walk around the compound. Look at the greenery. Smell the air. Feel your body temperature. All three pass, then go inside and check the floor plan. If one feels off, don't sign — no matter how good the floor plan.

1. Sheng Qi — Vegetation Glossy, Soil Lustrous, Air Sweet. Walk In and Breathe Smoothly. You Don't Want to Leave.

Sheng Qi is the only auspicious qi among the four. The literal meaning of Sheng Qi — qi that can "generate" all things. A place with ample Sheng Qi — vegetation is lush, soil is moist, air is fresh. People living here — healthy body, full spirit, smooth endeavors. Three hard indicators of Sheng Qi. First: look at the grass. Grassland with ample Sheng Qi — the grass color is "green with an oily sheen." Like grass washed clean by rain just fallen. Not dry green. Not yellow-green. It's glossy, vivid emerald. Touch the leaf surface — there's a thin layer of "moisture." Tree bark too — bark isn't dry and cracked. It has a lustrous feel. Second: look at the soil. Soil with ample Sheng Qi — color is deep brown or black-brown. Dig a little — the soil is moist but not sticky. Grab a handful and squeeze into a ball. When you release, the ball doesn't immediately crumble — the moisture level is just right. There are earthworms and small insects in the soil. Dead soil has none of these. Third: smell the air. A place with ample Sheng Qi — the air has a "sweetness." Not floral scent. Not grass scent. It's a "fresh sweetness of soil and plants blended together." Take a deep breath — the air reaches the bottom of your lungs. Exhaling feels crisp and clean. Not every well-landscaped compound has Sheng Qi. Some compounds have dense greenery, but the qi is "stuffy." Trees too dense, no ventilation — qi doesn't circulate. That's called "stagnant qi," not Sheng Qi. The core characteristic of Sheng Qi is "flowing without scattering." Qi moves (there's a gentle breeze) but isn't blown away (the terrain holds it). How to judge whether you're standing in Sheng Qi: close your eyes. Take three deep breaths. Feel how the airflow responds in your body. Breathing gets deeper — Sheng Qi. Breathing gets shallower, chest tightens — Si Qi or Yin Qi. Your body is more accurate than any instrument. Your body doesn't lie. A place you walk into and don't want to leave — you tell the agent "let me look a bit more" and unconsciously sit there for twenty minutes. That's Sheng Qi keeping you. Conversely, walk in and want to leave immediately — no matter how well the agent talks, you don't want to stay. The qi is wrong. Trust your first reaction.

2. Si Qi — Vegetation Withered, Soil Dark, Air Fishy-Rotten. Walk In and Your Chest Tightens. After Five Minutes You Want to Leave.

Si Qi is the opposite of Sheng Qi. Where Si Qi gathers — vegetation dies, soil is dead, the air is toxic. Not instantly deadly. It drains you slowly. A person living on Si Qi — three to five years, overall health comprehensively declines. Immunity drops. Chronic conditions flare. Spirit withers. Three hard indicators of Si Qi. First: look at the grass and trees. The lawn has large patches of withered yellow — not seasonal normal dieback. It's "dead yellow" — the kind that won't green up no matter how much you water. Tree trunks have large areas of bark peeling, tree hollows, or rotting from the core outward — the tree is already dying. On Si Qi trees, leaves fall a month earlier than surrounding trees. Spring budding also comes later. Standing under such a tree — you don't feel "sheltered." You just feel a chill. Second: look at the soil. Si Qi soil — the color is black. Not deep brown fertile black. It's "gray-tinged black." Like mixed with ash. The soil is dry — cracked dry. Or the exact opposite — it's sludge. Black, thick, sticky. Bubbles rising from it. A stench wafting up from the earth. No insects in the soil. Not even earthworms come. Third: smell the air. A Si Qi place — the air has a fishy smell, a rotten smell, a moldy smell. Often all three mixed together. Fishy — like the smell of a stagnant pond. Rotten — like the smell of leaves piled up rotting for three months. Moldy — like the smell of a basement that hasn't been ventilated all year. Take a deep breath — the air catches in your throat. You don't want a second breath. Causes of Si Qi: underneath is a landfill, an ancient burial ground, industrial waste fill zone, a long-term waterlogged underground pond, or abnormal groundwater causing soil hypoxia. All connected to "something buried underneath." High-risk Si Qi zones in urban planning: residential developments built on old industrial zones (decades of chemical waste leached into the soil), parks and compounds built on landfills (decomposing garbage below continuously generates Si Qi), sites of large former hospitals (I won't elaborate — you understand). Before buying, check what this land used to be. Government websites publish land-use history notices. Spend ten minutes checking. Save ten years of regret.

3. Yang Qi — Dry, Parched, Sparse Vegetation, Restless Energy Field. Stand Too Long and You Feel Agitated. Can't Sit Still.

Yang Qi itself isn't bad. All things need yang qi. But excessive Yang Qi is a problem. A place with excessive Yang Qi — dry, parched, sparse vegetation, lots of exposed soil and rock. People living here — temper worsens, sleep quality drops, skin dries, prone to inflammation. Three hard indicators of Yang Qi. First: look at the ground. Excessive Yang Qi ground — large areas of hardscape. Concrete, asphalt, stone slabs. At a glance, very little green. The soil is exposed and bare. Walking on it in summer — heat rises from the ground and steams upward. The soles of your feet burn. Second: look at the vegetation. Yang Qi-strong places — plants grow "hard." Small leaves, thorny branches, grayish-green color. Like cacti, agave, sisal. Or large patches of grass simply won't grow — only sparse, scattered strands. Trees too — thin trunks with tiny canopies. The trees are desperately shooting upward seeking shade. Third: feel your body temperature. An excessively yang place — walk in for ten minutes. Body temperature rises. Palms heat up. Face flushes. Throat dries. You want water. Can't calm your mind — inexplicably restless. Want to scroll your phone. Don't want to view the house anymore. Want to leave. This isn't your personality being impatient. It's the qi making you impatient. Common excessive Yang Qi scenarios in modern cities: ① compounds next to large plazas (the plaza absorbs heat all day and releases it at night — 24-hour yang energy baking); ② low-rise residences amid glass-curtain-wall building clusters (glass reflects sunlight onto your home — like being lit by three mirrors); ③ hilltop villas or high-rise penthouses (no taller buildings around to provide shade — sun beats down from morning to night with nothing to receive the yang energy). Remedy direction for excessive Yang Qi — "supplement yin." Plant more large-leaf greenery indoors. Place a fish tank or water feature. Change curtains to cool tones (blue, gray, white). Choose stone and tile for finish materials (cool nature) over wood (warm nature). But the fundamental solution is to pay attention to shading during house selection — a tall building in front that blocks the midday sun prevents excessive Yang Qi. Getting morning sun but escaping midday sun — optimal.

4. Yin Qi — Cold, Damp, Moss-Covered, Oppressive Energy Field. Stand Too Long and Your Shoulders Tighten. Your Body Wants to Curl Up.

Excessive Yin Qi, like excessive Yang Qi, is an imbalance. Yin Qi itself nourishes people. Sleeping at night relies on Yin Qi to contract Yang Qi. But too much Yin Qi — and a person withers. A place with excessive Yin Qi — damp, cold, sunlight never reaches, moss climbs the walls. People living here — joint pain, skin eczema, depressed mood, no drive to act. Three hard indicators of Yin Qi. First: look at walls and floors. A Yin Qi-heavy place — wall surfaces have water stains. Not a leak — it's moisture in the air condensing on the walls year-round, forming water marks. Floor corners have moss. Or walls have mold — black mold spots in patches. Bathrooms and kitchens are more obvious — black mold lines in the tile grout. Second: look at natural light. A Yin Qi-heavy place — you need lights on even during the day. Small windows, or windows blocked by neighboring buildings. Very brief direct sunlight each day — or none at all. Low floor + close building spacing = yin qi combo. Third: feel your body temperature. Walk in for five minutes — ankles feel cold. Then knees. Then shoulders. The body unconsciously curls inward — like standing in a cold storage. Walking in during summer and thinking "wow, so cool" — not a good thing. Normal coolness comes from ventilation. Yin Qi coolness is "yin cold" — unventilated cold. Pores close. Breathing becomes shallow. Mood sinks — inexplicably feel down. Don't want to talk. High-risk excessive Yin Qi zones in modern cities: ① ground floor or basement (closest to the earth — underground Yin Qi seeps directly up); ② low-rise residences boxed in by three high-rises (sunlight completely blocked — less than two hours of sun per day); ③ low-rise residences beside rivers, lakes, or the sea (heavy water vapor + sunlight scattered and weakened by water vapor); ④ narrow alleyways in old urban districts (building spacing under three meters — perpetually dark and damp). Remedy direction for excessive Yin Qi — "supplement yang." Open windows for ventilation more often. Pull all curtains fully open during the day. Keep lights on — especially in corridors and entryways (warm-toned light). Add more red and orange decorations indoors. Lay carpets — feet don't touch cold flooring directly. Place desiccants in wardrobes. But the fundamental solution is to avoid the four architectural environments above during house selection. A ground-floor unit's cheap price isn't free. The price difference gets reclaimed later at the hospital.

5. Harmonizing the Four Qi — No Place Has Only One Type of Qi. Learn to Read the Proportions.

In reality, no plot of land is pure Sheng Qi or pure Si Qi. Everything is a mix. A good plot — Sheng Qi dominates (about seventy percent), with a slight touch of Yang Qi (twenty percent) and a trace of Yin Qi (ten percent). People living here — good spirits, drive to act (Yang Qi's gentle boost), sleep soundly at night (Yin Qi's contraction). The proportions of the four qi determine "what kind of person this land nurtures." More Sheng Qi, less Yang Qi — suitable for convalescence, retirement, creative work (writers, painters, designers). Quiet. Not restless. But insufficient drive. Sheng Qi abundant with just the right Yang Qi — suitable for entrepreneurship, business, anyone needing daily motivation. Good spirits + drive. Salespeople living here — performance goes up. More Sheng Qi, more Yin Qi — suitable for meditation, spiritual practice, anyone needing deep thinking. But not suitable for ordinary people long-term. Yin Qi pulls a person's "action drive" downward. Over time, you don't want to move. More Yang Qi, less Yin Qi — suitable for young people. Abundant energy. Not afraid of dryness. Older people living here get insomnia and high blood pressure. Si Qi appearing in any combination — best to stay away. Si Qi isn't like Yin and Yang Qi, which can be harmonized. Si Qi is "qi that has already died." You can't "supplement" Si Qi with anything. The only option is to leave. Seasonal variation of the Four Qi: the same plot of land — spring brings rising Sheng Qi, summer brings rising Yang Qi, autumn balances yin and yang, winter lets Yin Qi dominate. A good plot maintains Sheng Qi as the dominant base throughout all four seasons. A bad plot — in certain seasons, Si Qi surges up. For example, spring and summer look fine, but as soon as autumn arrives, mold and stench emerge. When buying, ideally view the same plot in different seasons. If that's impossible — at least view during the "worst qi" season. Winter is the most honest for house viewing. Because winter has the weakest Yang Qi, the strongest Yin Qi, and Si Qi is easiest to expose. If the qi checks out in winter — no problem in other seasons. If winter already shows Si Qi and moldy smells — the green grass of spring and summer will deceive you.

Multi-Dimensional Breakdown

Career & Wealth

Good qi where you live — earning money isn't exhausting. Bad qi — exhausting but no money. A Sheng Qi-strong place — things go smoothly. Opportunities find you. No need to push desperately. A Si Qi place — you push desperately and get nowhere. Effort and reward don't match. Excessive Yang Qi — you have strong drive but no endurance. Start strong, finish weak. Earn fast money but can't keep it. Excessive Yin Qi — you have zero drive. Ideas exist but never become action. Enough money but never more. A Four Qi harmonized home — when you need to charge, Yang Qi lifts you. When you need to be steady, Yin Qi helps you contract. When you need to earn, Sheng Qi opens the path. All three in place — wealth follows your rhythm instead of you chasing wealth's rhythm.

Love & Relationship

A Sheng Qi-strong household — relationships are nurtured. Couples have things to talk about. Children are cheerful. Elders are spirited. The whole home is like "moist soil" — relationships grow naturally within it. Excessive Yang Qi — the household argues easily. Not major things. Just short tempers. Two sentences and it explodes. Excessive Yin Qi — the household is cold. People don't fight. But there's no warmth. Each on their own phone. Together but not really together. Si Qi — either frequent illness in the household (relationships consumed by sickness) or someone doesn't want to come home (the body instinctively avoids that environment). The Four Qi and relationships — your home is where you spend the most time daily. Its qi steeps you every day. Whatever qi you're steeped in — that's the qi you bring to face your partner.

Personality

Long-term residence in a Sheng Qi-strong place — confident but not arrogant. Gentle but not weak. Patient in action. Excessive Yang Qi place — irritable, competitive, conflict-prone. Classic "road rage" living environment. Excessive Yin Qi place — introverted, hesitant, prone to anxiety and depression. Voice gets softer. Afraid to express loudly. Si Qi place — a person goes numb. Nothing interests them. Not laziness — qi has been drained away. These personality traits start to surface about six months after moving in. Solidify after a year. After three years, you think "I've always been like this." Not true. The place raised you into this. Move to a different place for three months — you'll discover you're a different person.

Health

Sheng Qi nourishes the entire body. A Sheng Qi-strong home — after moving in, sleep deepens. Wake naturally in the morning. Good energy during the day. No need for coffee to stay alert. Excessive Yang Qi — inflammation. Mouth ulcers. Acne. Insomnia. Migraines. Dry skin. Wear fewer layers than others in winter but don't feel cold — it's dryness. Dryness without sweating. Excessive Yin Qi — cold-damp constitution. Joint pain. Eczema. Cold hands and feet. Especially for women — worsened menstrual pain. Uterine cold. Si Qi — chronically low immunity. Repeated colds. Allergies. Chronic inflammation. Medical checkups show nothing major but you always feel unwell somewhere. The Four Qi and health have the most direct connection. The body doesn't lie. If your health noticeably declines within a month of moving into a house — it's not coincidence. The qi is telling you: this place is uninhabitable.

Practical Steps

  • Three-Step House Viewing — Screen Once Each With Eyes, Nose, and Skin: Step one: walk around the compound. Don't listen to the agent. Put on headphones, play music. Walk alone. ① Check the greenery — is the grass glossy green? Any large patches of withered yellow? Any tree trunks with large areas of peeling bark or hollows? ② Smell the air — take three deep breaths. Any fishy, rotten, or moldy smell? Any "sweetness" in the air? ③ Feel your skin — after ten minutes, is your face flushed hot (excessive Yang Qi) or are your ankles cold (excessive Yin Qi)? Step two: enter the building. Not the unit yet. First, stand in the ground-floor elevator lobby for one minute. Smell the corridor air. Does the old corridor smell moldy? Are the lights on? Step three: enter the unit. First thing — turn off all the lights. Look at the house under natural light. If you need lights on during the day for normal activity — Yin Qi is heavy. Then open the windows — how does the outside air feel flowing in? Fresh, or the neighbor's cooking fumes? Three steps complete — you now have a bodily judgment of this place's qi. Now listen to the agent talk about the floor plan. If the qi is wrong — don't sign, no matter how good the floor plan.
  • View the Same Property Across Four Seasons — Winter Is Most Honest. If You Can't, View During the Worst Qi Weather.: If you can't view across all four seasons — choose winter for viewing. Winter has heavy Yin Qi, weak Yang Qi, and Si Qi exposes easily. Or choose a rainy day. A rainy day doubles a house's "dampness" — if walking in on a rainy day doesn't feel cold and clammy, sunny days are definitely fine. Conversely — a house viewed on a bright, sunny afternoon — all qi is "covered" by the sun. Si Qi baked by the sun — you can't see it. Yin Qi blocked by the sun — you can't feel it. Once the sun sets and you're living there — Si Qi and Yin Qi slowly float up. The worst trap is "a house viewed at 2 PM on a sunny day." That time of day, sunlight beautifies everything. The most honest times for qi reading: half an hour after sunrise (sun just rising, Yang Qi just starting, ground qi not yet baked away by the sun — you can smell the original scent), half an hour before sunset (sun about to set, Yin Qi beginning to rise — Yin Qi-heavy houses start smelling moldy at this time). View once at each of these two times. If the qi passes both — the house truly passes.

Frequently Asked Questions

Q:I'm renting and can't choose the compound — moved in and discovered the qi is wrong. How do I remedy?

A:

Rental with wrong qi discovered — first determine which type of qi problem. Excessive Yin Qi: open windows and doors for two hours of ventilation daily. Change all room lights to warm-toned, high-wattage. Place bamboo charcoal packs in corners to absorb moisture. Use an electric blanket on the bed (turn on for one hour before sleep to dry bedding moisture). Excessive Yang Qi: apply heat-insulating film to windows. Draw thin gauze curtains during the day. Place a fish tank or humidifier indoors. Lay light-colored carpets to reduce floor heat. Si Qi: seriously consider moving. Si Qi cannot be resolved. If it's mild Si Qi (only a certain corner smells moldy) — clear that corner completely. Place a snake plant + a salt lamp + ventilate frequently. But if it's overall Si Qi (the entire house feels uncomfortable) — don't tough it out. The deposit is minor. Your body is major. Your health is worth far more than two months' rent.

Q:Same building — does the qi differ much between low floors and high floors?

A:

It differs significantly. Low floors (1st–3rd) — receive the most ground qi. Yin Qi is heavy. Humidity is high. But Sheng Qi also comes directly (ground-level vegetation's Sheng Qi steams upward; low floors receive it first). The upside is receiving ground qi. The downside is receiving Yin Qi and also ground-level Si Qi. High floors (15th and above) — far from the ground. No ground qi received. Yin Qi is minimal. But Yang Qi is fierce — especially the top floor. Wind is strong. Qi is too dispersed. Can't hide from wind, can't gather qi. Middle floors (5th–12th) — most often the most balanced. Some ground-connecting Sheng Qi without excessive Yin Qi. Wind not strong enough to disperse qi. Which specific floor to pick — depends on your body constitution. Cold-prone people (cold hands and feet, afraid of cold) — don't pick too low. Pick middle-high. Poor sleep quality (insomnia, shallow sleep) — don't pick too high. Wind disperses qi; sleep gets worse. Pick middle-low. Healthy people — pick freely. The body's environmental adaptability is strong enough — any floor can be adjusted to.
