How to Fix Old House Issues? Gu Hexagram First Yin Line: "干父之蛊，厉终吉" (Tackling Father’s Decayed Legacy: Danger Ends in Good Fortune) — Old Problems Need Early Fix, Delay Brings Bigger Trouble

What’s it like to live in an old house?

It might be an old home left by your parents, a second-hand apartment you bought, or an ancestral estate passed down through generations.

Once you move in, something always feels off—poor lighting, bad ventilation, an awkward layout, a general sense of unease. On top of that, small mishaps keep popping up at home, and you feel tired all the time.

You suspect there’s something wrong with the house, but you’re not sure—Is it a real issue, or am I just overthinking?

You want to get someone to check it out, but you’re afraid of running into unreliable people. You want to fix things, but you don’t know where to start. You want to move out, but you can’t afford to.

So you live there half-convinced, half-doubting, and the longer you stay, the more uncomfortable and unlucky you feel.

When an old house has problems, what on earth should you do?

The first line of the Gu Hexagram, the Six at the Beginning, has the answer: 「干父之蛊，有子，考无咎。厉，终吉。」 (Gān fù zhī gǔ, yǒu zǐ, kǎo wú jiù. Lì, zhōng jí. / Setting right what has been spoiled by the father. If there is a son, the father incurs no blame. Danger, but in the end good fortune.)

The Gu Hexagram is about: someone has to clean up the mess left by predecessors

What is the Gu Hexagram? It’s 山风蠱 (Shān Fēng Gǔ), Gen (Keeping Still) on top and Xun (The Gentle) below—wind beneath the mountain.

Wind blows at the foot of the mountain, but the mountain blocks it. When the air can’t circulate, problems arise over time: things rot, pests breed, decay sets in. That’s what “gu” means.

The Gu Hexagram is about accumulated ills, leftover problems, the mess left by those who came before—and how to clean it up, fix it, and turn things around.

The Six at the Beginning is the first line of the Gu Hexagram. A Yin Line at the very bottom, it holds the lowest position and has the weakest power. But what is it tasked with? “Setting right what has been spoiled by the father”—it must fix the problems left by the older generation, clean up the mess left by predecessors.

Is it easy for someone who’s just starting out, with little power, to take on such a tough challenge?

No, it’s not. That’s why the Line Text says “lì” (厉)—there’s danger, hardship, and pressure.

But what about the outcome? “Zhōng jí” (终吉)—in the end, it is auspicious.

Why? Because the earlier you deal with a problem, the better. It’s hard at first, but things get smoother as you go. If you put it off until the problem grows, it becomes a real headache.

What does “If there is a son, the father incurs no blame” mean?

It means when the son steps in to clean up, take responsibility for, and correct the problems left by his father, the father’s mistakes are made up for, and there is no blame.

How does this apply to the old house situation?

Your old house—maybe built by your parents, passed down from ancestors, or left by the previous owner—has all kinds of old issues: unreasonable layout, aging wiring, poor lighting, bad ventilation, even leftover bad habits or old customs.

These problems aren’t your fault; they were left by those who came before. But since you live there, you have to face them and deal with them.

Fixing them isn’t just good for you—it’s also tying up loose ends for your predecessors. That’s “the father incurs no blame”: when you solve the problems left by those before you, they have no more regrets or faults to answer for.

What do you call that? It’s called taking responsibility. It’s also called filial piety.

Why old house problems get worse the longer you wait

Many people living in old houses notice all kinds of problems, but they always say—

“Oh well, old houses are like that.”

“Just make do, we’ll deal with it later.”

“Fixing it is too much trouble, let’s leave it for now.”

What happens? The problems get bigger, worse, and harder to fix the longer you wait.

It might start as a small issue, but if you put it off, it becomes a big problem. The money, effort, and suffering all double.

Why do people put off fixing things? Three reasons.

First, they hate the hassle.

They think fixing old problems is too much work—costs money, takes time, and is a whole ordeal. So they just make do.

Second, they’re afraid to make changes.

They think old houses have rules and traditions from the older generation. They’re scared of messing things up, offending people, or causing trouble.

Third, they don’t know how to fix things.

They want to deal with it, but they don’t know where to start, how to make changes, or if the changes will even help.

At the end of the day, these three reasons boil down to one word—wait.

Wait until later, wait until conditions are better, wait until you’ve figured it all out.

While you’re waiting, small problems become big ones, big problems become headaches, and headaches become unsolvable messes.

The Six at the Beginning tells you—don’t be afraid, don’t wait, don’t delay.

“Danger, but in the end good fortune”—it’s hard at first, takes effort, and has risks, but the end result is always good.

Why am I so sure?

Because the problem is right there. It won’t go away on its own if you ignore it—it’ll only get bigger. Deal with it early, and the problem is small, the cost is low, and it’s easy to fix. Deal with it late, and the problem is big, the cost is high, and you might not even be able to fix it properly.

Deal with it early, and you’re in control. Deal with it late, and you’re at its mercy.

Taking initiative to fix the mess is called “dealing with gu.” Being pushed around by the mess is called “being tormented by gu.” They’re completely different.

How to actually deal with old house problems

So how do you specifically fix old house problems? Three principles, matching the wisdom of the Six at the Beginning.

First, figure out the problem clearly first.

“Setting right what has been spoiled by the father”—you have to first understand what the problem is, where it is, and how it started. Don’t just jump in and randomly change, demolish, or rearrange things.

Do a full inspection first. Are there structural issues? Hidden dangers with plumbing and wiring? Hard flaws in the layout? Is ventilation and lighting sufficient?

The worst thing you can do with an old house is mess around blindly. One day you decide you don’t like a wall and knock it down, the next you hate the floor and pry it up, the day after you think the kitchen is too small and remodel it. After all that back-and-forth, you’ve spent a ton of money, haven’t solved the problem, and might even have created safety hazards.

Figure it out first, then take action. Don’t act recklessly.

Second, start small.

The Six at the Beginning is the first line—it’s the starting point, not a full overhaul all at once. Start with the most urgent, most life-impacting fixes, and take it step by step.

For example, if there are wiring or plumbing hazards, fix those first—they’re a matter of safety. If lighting is bad, move things that block light, switch to thinner curtains, paint the walls white. If ventilation is poor, install an exhaust fan and open windows more often.

Solve the small problems first, then tackle the big ones slowly.

Don’t try to do everything at once, don’t start with massive demolition and construction—that’s how problems happen.

If you look at well-done old house renovations, none of them were finished in one go. People move in, fix what bothers them, adjust gradually, and the place gets more and more comfortable over time.

Houses have their own “personality” too—you have to get used to each other slowly.

Third, stick to your bottom line.

The premise of “danger, but in the end good fortune” is that you do things the right way, use correct methods, and don’t act foolishly.

Renovating a house requires science, safety, and rules. You can’t knock down load-bearing walls just for looks, use cheap materials to save money, or mess around with weird, unproven tricks.

Only proper, down-to-earth repairs and renovations lead to “good fortune in the end.”

One thing to especially note—don’t blame everything on mysticism.

If an old house feels uncomfortable to live in, it’s most likely a physical problem: bad lighting, poor ventilation, unreasonable layout, bad sound insulation, strange smells. All of these can be solved with scientific methods.

Don’t immediately assume it’s a feng shui issue, hanging mirrors and pasting talismans left and right. After all that fuss, not a single real problem gets solved.

Fix the physical problems you can solve first, then talk about anything else.

Final thoughts

The Xiang Commentary (象傳) says: “Setting right what has been spoiled by the father—his intention is to carry on the work of his father.”

Correcting the mistakes of the older generation comes from a desire to carry on the predecessors’ wishes, to finish what they didn’t do well.

When you fix the problems in your old house, you’re not just making it more comfortable for yourself—you’re also carrying forward the wishes of those who came before you, taking good care of the family property they left behind.

An old house isn’t a burden—it’s your roots.

Only when you fix the problems at the root can you live with peace of mind, stability, and越来越好 (better and better).

What’s the core principle of the Gu Hexagram? 元亨利貞 (Yuán Hēng Lì Zhēn / Originating, Penetrating, Advantageous, Correct). It furthers one to cross the great water. Three days before the Jia day, three days after the Jia day.

When accumulated ills reach a certain point, they must be rectified and renewed. Once rectified, there will be great success and development. But rectification can’t be done recklessly—you have to think things through from start to finish, be thorough, and not rush.

As the first line, the Six at the Beginning is the starting point of rectification—it’s the hardest and most dangerous at first, but as long as the direction and methods are right, the end result will always be auspicious.

It’s the same with your home: fixing old house problems is the most troublesome at the beginning. You have to inspect for issues, find the causes, think of solutions, and make changes—all kinds of hassle. But as long as you follow a plan and take it step by step, once the renovations are done, the house will feel right, living there will be comfortable, and the whole atmosphere of your home will improve.

So how do you deal with old house problems?

Don’t delay, don’t be afraid, take it slow. First figure out where the problem is, then start small, and clean up the mess left by predecessors step by step.

It’s a bit of work at first, but things get smoother as you go, and the end result is always good.

Putting off solving problems is the biggest problem of all.

Wen Laoshi once said—houses have their own temper. If you treat them well, they’ll treat you well. If you neglect them, they won’t let you be comfortable.

May you take good care of your home, make it cozy, and live there with peace and stability.
