Work on What Has Been Spoiled
蛊
Upper: 艮/山 | Lower: 巽/风
Overview
Gu (Work on What Has Been Spoiled / Decay) is the eighteenth hexagram of the I Ching, composed of Wind (Xun) below and Mountain (Gen) above. Wind beneath the mountain symbolizes wind blocked and stagnating, extended to mean corruption and accumulated problems. The character 'Gu' originally refers to worms breeding in a vessel left unused for three days, metaphorically describing the decay that results from prolonged complacency. Gu is the inverse hexagram of Sui (Following)—prolonged following inevitably breeds accumulated problems requiring reform. The Sequence of Hexagrams states: 'He who follows others with joy will surely have affairs to deal with, hence Gu follows.' The core wisdom of Gu lies in understanding that corruption itself is not fearsome—what is fearsome is the refusal to confront and remedy it. Though Gu speaks of decay, it carries the judgment of 'supreme success,' because rectifying corruption is itself a great undertaking.

The judgment of Gu—'Supreme success. It furthers one to cross the great water. Before the starting point, three days. After the starting point, three days'—is filled with the spirit of positive reform. 'Supreme success' declares that rectifying corruption leads to great prosperity—giving reformers tremendous confidence. 'It furthers one to cross the great water' encourages bravely facing difficulties and overcoming obstacles. Most ingenious is 'before the starting point, three days; after the starting point, three days.' 'Jia' (the starting point) is the first Heavenly Stem, representing a new beginning. 'Three days before' is the Xin day, meaning one must thoroughly reflect on past lessons before reform; 'three days after' is the Ding day, meaning one must continue monitoring and consolidating results after reform. This reveals a complete methodology for reform: reflection → action → consolidation—none can be omitted.

The wind blows low on the mountain: the image of Decay. Thus the superior man stirs up the people and strengthens their spirit.
Image Commentary
The Image text—'The wind blows low on the mountain: the image of Decay. Thus the superior man stirs up the people and strengthens their spirit'—unites natural phenomena with governance. 'Wind blowing low on the mountain' depicts wind swirling at the mountain's base, unable to flow freely—wind that should move unobstructed is blocked by the mountain's mass and stagnates, just as righteous energy in society is obstructed by accumulated corruption. The superior man emulates this pattern with two measures: 'stirring up the people' means reviving public spirit and eliminating corrupt practices, restoring society's vitality; 'strengthening their spirit' means cultivating virtue and educating the populace, fundamentally preventing corruption from recurring. 'Stirring the people' treats symptoms; 'strengthening spirit' treats root causes—addressing both is the proper way to remedy decay.
Interpretation
Gu symbolizes decay and the work of reform. Wind at the foot of the mountain is stagnant. After corruption, renovation and correction are needed.
Line Texts
Six at the beginning: Setting right what has been spoiled by the father. If there is a son, no blame rests upon the departed father. Danger. In the end, good fortune.
Correcting the father's decay. A capable son removes blame from the departed. Danger, but good fortune in the end.
The first six, a yin line at the beginning of Gu, symbolizes a young person confronting the accumulated problems left by the previous generation. 'Setting right what the father has spoiled'—'setting right' means to rectify and correct. The son must bravely correct the father's mistakes. 'If there is a son, the father is without blame' means that with such a capable heir, the father's faults will not be held against him. 'Danger, but good fortune in the end' warns that though the process is perilous, the final outcome is auspicious. The first six encourages the younger generation not to turn a blind eye to predecessors' errors out of deference to hierarchy—courageous reform is the truest form of filial piety.
Nine in the second place: Setting right what has been spoiled by the mother. One must not be too persevering.
Correcting the mother's decay. Do not be too forceful; gentleness is needed.
The second nine, a yang line achieving centrality, corresponds with the fifth six. 'Setting right what the mother has spoiled' refers to rectifying problems caused by the mother (yin, yielding)—requiring more finesse than correcting the father's mistakes. The mother symbolizes the soft, emotional dimension; correcting such problems cannot employ forceful methods but must 'not be too persevering'—not excessively rigid or unyielding. The second nine, in the central position, deeply understands the way of the mean, knowing that reform requires both determination and flexibility. This resembles handling interpersonal relationships during corporate reform—one must advance institutional change while not completely disregarding human feelings, combining firmness with gentleness.
Nine in the third place: Setting right what has been spoiled by the father. There will be a little remorse. No great blame.
Correcting the father's decay. Some regret, but no great blame.
The third nine, a yang line atop the lower trigram, is excessively firm without centrality. 'Setting right what the father has spoiled' echoes the first line, but the third nine's approach is more forceful and radical. 'There will be a little remorse, but no great blame' indicates that though the overly aggressive methods will cause minor regrets, they won't lead to major fault. The third nine's reform style resembles 'overcorrection'—going to the opposite extreme in order to correct an error. Though imperfect, it is still better than no reform at all. Sometimes reform requires precisely this kind of boldness—'better to go too far than not far enough.'
Six in the fourth place: Tolerating what has been spoiled by the father. In continuing one sees humiliation.
Tolerating the father's decay without correction. Continuing this way leads to humiliation.
The fourth six, a yin line at the base of the upper trigram, has no correspondence with the first six. 'Tolerating what the father has spoiled'—'tolerating' means being lenient and permissive, taking an accommodating attitude toward inherited problems without rectifying them. 'Going on brings humiliation' warns that continuing such permissiveness will inevitably lead to disgrace. The fourth six's error lies in a 'nice person' style of inaction—knowing problems exist but not daring to address them, using tolerance to mask cowardice. This is the most dangerous attitude in reform, because corruption does not disappear through tolerance—it only accumulates and deepens.
Six in the fifth place: Setting right what has been spoiled by the father. One meets with praise.
Correcting the father's decay brings praise and honor.
The fifth six, a yin line in the ruler's position, corresponds with the second nine. 'Setting right what the father has spoiled, one meets with praise' indicates that rectifying inherited problems earns a fine reputation. Though inherently yielding, the fifth six occupies the central position with the virtue of the mean and can leverage the second nine's yang strength to implement reform. 'Meeting with praise' shows that the fifth six's reform approach wins people through virtue and rallies support through reputation—not through coercive power but through moral inspiration. This represents the ideal reform model: the ruler possesses the vision and determination for reform, the minister possesses the capability and courage, and sovereign and minister cooperate with unified purpose.
Nine at the top: He does not serve kings and princes, sets himself higher goals.
Not serving kings and princes. One sets higher goals and transcends worldly affairs.
The top nine, a yang line at the extreme of Gu, transcends the specific work of rectification. 'Not serving kings and princes, setting one's aims high' means no longer serving rulers but pursuing a nobler calling. The top nine has completed the mission of combating corruption and now chooses withdrawal, focusing on spiritual cultivation and scholarly legacy. This is not shirking responsibility but the wisdom of retiring after success. Historical figures like Fan Li and Zhang Liang both withdrew at the height of their achievements, preserving themselves while securing lasting renown. The top nine teaches us: knowing when to withdraw is equally as important as knowing when to advance.
Modern Application
Gu is the quintessential 'reform hexagram,' ideal for corporate restructuring, process optimization, and team reorganization. 'Three days before, three days after' reminds us to thoroughly research before reform and continuously follow up afterward. The first line's 'setting right what the father has spoiled' encourages young people to bravely correct problems left by predecessors. The second line's 'setting right what the mother has spoiled' reminds us that reform should be gentle and gradual, never rushed
Gu symbolizes accumulated grievances and problems in a relationship. When cracks appear, don't avoid them—face them bravely and actively repair them, as Gu teaches. The fourth line's 'tolerating the father's decay' warns that excessive tolerance of problems only worsens the situation
Gu reminds us to clean up bad assets and optimize investment portfolios. Cut losses decisively on failing projects ('setting right the father's decay') rather than continuing to invest due to sunk costs. The top line's 'not serving kings and princes' suggests that sometimes withdrawing from the market and preserving oneself is the wisest move
Gu symbolizes accumulated toxins in the body, making it ideal for detoxification and dietary adjustment. Chronic illness sufferers should especially heed 'three days before'—identifying root causes matters more than treating symptoms

Get AI Reading →Historical Story
The most celebrated historical story associated with Gu is Shang Yang's reforms in the state of Qin. When Duke Xiao of Qin ascended the throne, Qin was deeply corrupted—aristocrats monopolized power, laws had fallen into disuse, and the army was demoralized. Shang Yang was tasked with reform. He first established public trust through the famous 'moving the wooden pole' demonstration (three days before), then implemented a series of reforms including abolishing the well-field system, rewarding military merit, and standardizing weights and measures (the starting point), ultimately transforming Qin from a weak state into a fearsome military power. Another famous story is Wang Anshi's reforms during the Northern Song dynasty. By mid-Song, the empire suffered from accumulated poverty and weakness. Wang Anshi implemented new policies including the Green Sprouts Law, the Hired Service Law, and the Baojia mutual security system. Though ultimately defeated by conservative opposition, his reformist spirit—'Heaven's changes need not be feared, ancestral ways need not be followed, people's words need not be heeded'—vividly embodies Gu's judgment of 'supreme success, it furthers one to cross the great water.'
