At UK MASTER ACADEMY, no hexagram is read in isolation. Classical Chu Yi analysis situates Corners of the Mouth within its Upper-Lower trigram dynamic alongside three structural counterparts: the Nuclear Hexagram (hidden internal progression), the Opposite Hexagram (complete Yin-Yang polarity inversion), and the Inverse Hexagram (180-degree perspective reversal):

📊 Line-by-Line Commentary: All 6 Moving Lines & Transformations

Counted from the bottom upward (Initial, Second, Third, Fourth, Fifth, and Top), the six lines trace the complete arc of an affair from inception to culmination. When casting with our Three-Coin I Ching Tool or Plum Blossom Divination Calculator, focus on the moving line(s) alongside the resulting Transformed Hexagram:

Line 1 · Nine at the Beginning Yang Line · Parents (Fu Mu) · Water · Response Line Changes to Hexagram 23: Bo
Line Text: You cast aside your own sacred tortoise and watch another's jaws at their chewing; inauspicious.
Lesser Image: To watch another's jaws at their chewing and to crave it is not worthy of esteem.

Master Ưng Khiêm's Commentary: You have talent and a character of your own, like the sacred tortoise that nourishes itself on its own pure breath, and yet you let that precious thing go in order to envy what another has on his plate. I have seen that this is a great pity: a person holds something of value in hand and does not know how to use it, and instead looks at another's enjoyment and falls into a low craving. To feed yourself by leaning on the sight of others is to lose yourself.

When Line 1 Moves in Divination: Wealth: do not compete with another's way of living and so forget your own capacity. Work: hold to what you are good at, and do not stand on this hill looking at that one. Love: do not measure yourself against others and lose your own worth. Health: eat according to your own needs and do not chase after fashions. Decisions: return to what is precious in yourself and stop running after what is outside.
Strategic Counsel: You hold the sacred tortoise in your hands and do not value it; keep staring at another's mouth and you will lose the worth that is your own.
Line 2 · Six in the Second Place Yin Line · Siblings (Xiong Di) · Wood Changes to Hexagram 41: Sun
Line Text: Nourishment sought upside down, against the normal order, seeking nourishment on the high hill; to advance is inauspicious.
Lesser Image: The Six in the Second Place line is inauspicious if it advances, because in acting it loses the companions of its own kind.

Master Ưng Khiêm's Commentary: You are in a place where you must depend on someone, but if you seek that support from the wrong person or in the wrong place, you will go against the normal order and lead yourself into a dead end. I have seen that this line gives a delicate reminder: you cannot nourish yourself by leaning on just anyone, you must choose the right person and the right Way. If you set your sights on the high and grand and beg where it does not fit, you will only bring isolation upon yourself.

When Line 2 Moves in Divination: Wealth: do not borrow from or ask favours of the wrong person, or you may lose both the money and the friendship. Work: choosing the wrong patron will only tangle matters further. Love: do not seek support where it does not match you, or you will find yourself alone. Health: the wrong method of treatment will make the illness worse. Decisions: stop, and review the direction you have chosen.
Strategic Counsel: Nourishment must follow the right Way and the right person; seeking support in the wrong place leaves you adrift in the world.
Line 3 · Six in the Third Place Yin Line · Wife and Wealth (Qi Cai) · Earth Changes to Hexagram 22: Bi
Line Text: Going against the Way of nourishment, inauspicious even if one holds to correctness; for ten years do not act; there is nothing to gain.
Lesser Image: For ten years do not act, because the great Way has been too gravely transgressed.

Master Ưng Khiêm's Commentary: You are neither centred nor correct here, and unchecked appetite has carried your way of nourishing yourself far from what is right; this is the worst line in Di. I advise you plainly that at such a time even keeping up an appearance of propriety will hardly avert a bad outcome, and you must look again at the very root of your way of living and your habits. Ten years stands for a long stretch of time in which a thorough correction is needed, not something to be patched over.

When Line 3 Moves in Divination: Wealth: your way of doing business has gone seriously astray and must be halted and mended from the root. Work: the present direction is unsound; do not force yourself to continue on it. Love: this relationship is drifting away from what is right and deserves a serious reconsideration. Health: your daily habits are harming your body and must be changed thoroughly. Decisions: stop altogether and do not try to patch things up.
Strategic Counsel: When the way of nourishment has strayed too far, what is needed is not a small repair but a halt and a fresh beginning from the root.
Line 4 · Six in the Fourth Place Yin Line · Wife and Wealth (Qi Cai) · Earth · World Line Changes to Hexagram 21: Shi He
Line Text: Nourishment sought upside down, yet auspicious; the tiger watches with an intent gaze, its desire pursuing without pause; no blame.
Lesser Image: Nourishment upside down is auspicious, because the light of virtue shines down from above.

Master Ưng Khiêm's Commentary: You are in a high place yet humble enough to seek out able people below you and lean on their wisdom; in form this looks inverted, but in substance it accords with the Way, because your wish for worthy helpers is sincere. I liken you to the tiger with its fixed gaze, pursuing a rightful aim with resolve rather than a common appetite. Such strong and steady concentration, when it is turned towards what is right, deserves no blame.

When Line 4 Moves in Divination: Wealth: seek out able partners boldly, even if they stand lower than you. Work: seek out the worthy and give real responsibility to those with true ability. Love: to pursue sincerely the one you love is entirely proper. Health: firm resolve in your treatment will bring good results. Decisions: pursue the aim you have set with confidence.
Strategic Counsel: To humble yourself and seek out able people is no weakness; it is the wise road to nourishing a great enterprise.
Line 5 · Six in the Fifth Place Yin Line · Parents (Fu Mu) · Water Changes to Hexagram 42: Yi
Line Text: Against the normal order, yet to stay still and hold to correctness is auspicious; one should not cross the great river.
Lesser Image: To stay still and hold to correctness is auspicious, because one knows how to yield and lean on the one above.

Master Ưng Khiêm's Commentary: You are in a high place but you know your own strength has its limits and that you cannot nourish the world by yourself, so you wisely lean on the worthy talent below you to carry the load together. I have seen nothing shameful in this; it is knowing others and knowing yourself, and what matters is to keep your integrity intact while you lean. But just now you must on no account risk a great undertaking alone, for your strength is not yet sufficient.

When Line 5 Moves in Divination: Wealth: work with someone more capable than you and do not risk a great venture on your own. Work: hold your position steady and do not launch a project beyond your reach. Love: rely on the counsel of those close to you and keep the relationship stable. Health: take care of yourself and avoid risky exertion. Decisions: stay where you are and hold firm; this is not the time for adventure.
Strategic Counsel: To know that you cannot yet carry a great task alone and to look for a worthy person to lean on is wisdom, not weakness.
Line 6 · Nine at the Top Yang Line · Siblings (Xiong Di) · Wood Changes to Hexagram 24: Fu
Line Text: Nourishment for others flows from you; to be watchful is auspicious; it is favourable to cross the great river.
Lesser Image: Nourishment flowing from oneself, watchful and therefore auspicious, this is a matter for great rejoicing.

Master Ưng Khiêm's Commentary: You have reached the summit of Di and become the one on whom the whole world depends for its nourishment; the responsibility is very heavy. I remind you that precisely because you carry so much, you must keep a careful heart at all times, thinking ahead to what is distant and mindful of what is near, if you are to be worthy of this place. When your virtue and ability are enough to make you a support for others, this is the favourable time to take on the great task, and even a difficulty like crossing a river can be crossed.

When Line 6 Moves in Divination: Wealth: you have the strength for a great undertaking and may invest on a large scale, but stay careful throughout. Work: take up the role of leading and nourishing the team beneath you. Love: become a firm support for your family. Health: your strength suffices for heavy responsibility, yet you must still take care. Decisions: you may undertake great things, but always keep a careful frame of mind.
Strategic Counsel: The more you stand as a support for many, the more you must keep a careful and far-sighted heart; that is how blessings are held for a long time.

🌟 Practical Divination Across Major Life Domains

Overall strategic trajectory of Hexagram 27 Corners of the Mouth · UK MASTER ACADEMY

1. Overall Trajectory & Strategic Timing

Mountain above and Thunder below, thunder beneath the mountain. This is the image of nourishment. Be careful with your words and with what you eat. Nourish yourself and nourish others in the right way. Because Gen (Mountain) (Earth) rides above Zhen (Thunder) (Wood), the hexagram asks you to align inner preparation (arousing movement, awakening, decisive action) with outward execution (keeping still, boundary-setting, calm stability).

Core Decision Principle: Below the mountain there is thunder; the noble one is careful with his words and temperate in eating and drinking. At the ruler's fifth position, classical guidance emphasizes: stay where you are and hold firm; this is not the time for adventure.

2. Career, Leadership & Financial Strategy

Career & Governance: In the opening phase (Line 1), the counsel for work is clear: hold to what you are good at, and do not stand on this hill looking at that one. As the hexagram matures to its fifth position (Line 5), leadership reaches its decisive test: hold your position steady and do not launch a project beyond your reach. Anchor your authority on the World Line (Line 4) while observing how counterparts respond at Line 1.

Wealth & Capital Allocation: Early financial posture requires discipline: do not compete with another's way of living and so forget your own capacity. When conditions ripen at the fifth line, capital movement shifts: work with someone more capable than you and do not risk a great venture on your own. In Six Lines casting, examine the Wife and Wealth (Qi Cai) line within the Xun Palace table above to judge liquidity and timing.

3. Relationships, Marriage & Family Harmony

Relational harmony depends on the resonance between the Inner Trigram (Zhen (Thunder), self/home) and Outer Trigram (Gen (Mountain), partner/environment). In the developing inner stage (Line 2), relationship dynamics indicate: do not seek support where it does not match you, or you will find yourself alone. At maturity (Line 5), the bond reflects: rely on the counsel of those close to you and keep the relationship stable.

Remember to cross-check the Nuclear Hexagram (Hexagram 02: The Receptive) when unspoken emotional expectations or family pressures sit beneath the surface.

4. Health, Constitutional Qi & Medical I Ching

In classical Medical Yi (Yi Yi), Gen (Mountain) corresponds to the hands, spine, joints, stomach, upper digestive tract, whereas Zhen (Thunder) governs the feet, liver, gallbladder, sinews, nervous reflexes. Early moving-line diagnostics note: eat according to your own needs and do not chase after fashions. At the uppermost extreme (Line 6), guard against overextension: your strength suffices for heavy responsibility, yet you must still take care.
