Hexagram Identification
- Number: 18
- Chinese Name (Pinyin): 蛊 (Gǔ)
- English Name: Decay
- Symbol & Structure: ䷑ (Xùn 巽 below, Gèn 艮 above). The lower trigram Xùn represents Wind (风 fēng, subtle penetration, adaptability), and the upper trigram Gèn represents Mountain (山 shān, stability, boundaries). Together, they form “Mountain over Wind” (山风蛊 shān fēng gǔ), symbolizing the process of addressing decay—wind eroding a mountain’s cracks, revealing hidden rot, and prompting renewal. The structure features a Yang line at the top (Gèn’s firmness) and Yin lines below (Xùn’s flexibility), embodying the balance between decisive action and adaptive strategy in overcoming stagnation.
Keywords
- Decay (蛊): Addressing corruption or stagnation
- Renewal (革新): Restoring vitality through systemic change
- Rectification (整治): Correcting issues at their root
- Inherited Challenges (承弊): Resolving problems passed down through time
- Wise Leadership (贤能): Guiding renewal with vision and empathy
- Patient Reform (渐进改革): Transforming decay through steady effort
- Responsible Inheritance (克绍箕裘): Honoring roots while adapting to change
- Structural Healing (系统修复): Rebuilding from foundational cracks
Historical Context
Gǔ appears as the 18th I Ching hexagram, following Suí (Following, 17th) and preceding Lín (Approach, 19th). Its name “蛊” originally referred to “worms in grain” (蛊 gǔ), evolving to mean “decay,” “corruption,” or “accumulated stagnation.” The judgment “Gǔ: 元亨，利涉大川；先甲三日，后甲三日” (“Decay: Great prosperity. Beneficial to cross a great river. Three days before Jia, three days after Jia”) emphasizes that resolving decay requires both courage (crossing rough waters) and timing (preparing before/after key moments).
Classic interpretations include:
- Wang Bi (3rd century): In Commentary on the I Ching (《周易注》), he stressed “rectifying decay through virtue” (以德治蛊 yǐ dé zhì gǔ), arguing that moral leadership dissolves corruption.
- Kong Yingda (7th century): In Zhouyi 正义 (《周易正义》), he linked Gǔ to “renewing outdated systems” (革故鼎新 gé gù dǐng xīn), using the example of kings reforming laws to restore order.
- Zhu Xi (12th century): In The Meaning of the I Ching (《周易本义》), he emphasized “firmness above, flexibility below” (刚上柔下 gāng shàng róu xià), advising leaders to balance strength with adaptability during renewal.
Historically, Gǔ guided discussions on political reform, family ethics, and personal discipline, highlighting the necessity of confronting decay to achieve renewal.
Core Interpretation
Gǔ embodies the principle of “transforming decay through wise intervention”. Xùn’s Wind (Yin, penetrating subtly) below symbolizes the ability to uncover hidden issues, while Gèn’s Mountain (Yang, stable action) above represents the resolve to rebuild. The hexagram’s structure—with four Yin lines (receptive, problematic) and two Yang lines (active, corrective)—reflects the tension between stagnation (Yin) and renewal (Yang).
- Yin-Yang Dynamics: The 2nd Yang line (九二) and 5th Yang line (九五) act as anchors of “central correctness” (中正 zhōng zhèng), advising that effective rectification requires both ethical clarity (Yang) and nuanced strategy (Yin).
- Five Elements: Xùn (Wind) belongs to Wood (木 mù), Gèn (Mountain) to Earth (土 tǔ). Wood erodes Earth (木克土 mù kè tǔ), symbolizing how persistent effort (Wood) can break down rigid decay (Earth), but must be applied with precision to avoid chaos.
Symbolic Representation
Natural Symbolism
- Mountain over Wind (山风): Wind wearing down a mountain’s surface, exposing cracks and clearing debris—nature’s way of renewing landscapes by removing decay, like a forest regenerating after a controlled burn.
- Tree Roots and Rocks: Roots (Wind’s subtlety) growing into rocky soil (Mountain’s rigidity), symbolizing how small, persistent actions can transform stagnant environments.
Social Symbolism
In human affairs, Gǔ applies to:
- Organizational Reform: A company restructuring after years of mismanagement, using data analysis (Wind’s insight) and decisive leadership (Mountain’s firmness) to restore health.
- Family Healing: Addressing generational conflicts by acknowledging past wounds (Wind uncovering issues) and fostering dialogue (Mountain’s stable communication).
Cultural Symbolism
- Confucian Rectification: Aligns with Confucius’ “correcting names” (正名 zhèng míng) to restore social order, such as a leader redefining team values to combat toxicity.
- Taoist Renewal: Echoes Laozi’s “return to the root” (复归其根 fù guī qí gēn), where addressing foundational decay (e.g., personal habits) leads to lasting change.
- Ritual Purification: Ancient ceremonies clearing impurities from temples or villages, embodying Gǔ’s theme of symbolic and practical renewal.
Qualities and Attributes
Gǔ celebrates virtues that transform decay into renewal:
- Courageous Vision (果敢远见): Like a leader identifying systemic issues, having the bravery to initiate reform.
- Subtle Insight (敏锐洞察): Detecting hidden problems, as a doctor diagnoses underlying health issues from minor symptoms.
- Patient Persistence (坚韧坚持): Staying committed to long-term solutions, such as a teacher mentoring a struggling student over months.
- Responsible Inheritance (担当传承): Honoring past legacy while adapting to present needs, like a family business modernizing without losing its values.

Essence Summary
Gǔ, the I Ching’s Hexagram of Decay, reveals a profound truth: decay is not an end, but a call to renewal—a chance to transform stagnation into strength through wisdom, courage, and patience. Its image of Mountain over Wind teaches us that like wind eroding a mountain to reveal new paths, life’s greatest renewals begin with acknowledging hidden issues and embracing the discomfort of change.
In a world where systems, relationships, and habits inevitably accumulate decay, Gǔ offers a blueprint for revival: look beneath the surface, honor the past while adapting to the present, and lead with both firmness and empathy. Whether revitalizing an organization, healing a family rift, or transforming personal habits, the hexagram reminds us that renewal is not a single act, but a journey—one that requires seeing decay as a catalyst, not a curse.
Ultimately, Gǔ celebrates the beauty of “responsible renewal”—a process that respects the roots of what came before while having the courage to plant new seeds for the future. It invites us to view decay not with despair, but with the vision to see beyond it, trusting that even the most stagnant landscapes can bloom again when met with patience, wisdom, and the courage to begin.
