Wind over lake, with a hollow at the centre of the figure. Zhong Fu is trust that goes all the way down, and the character behind it is the one used for a bird brooding an egg.
Sixty-first in the King Wen order. The Sequence places it after Limitation: once a measure has been set and holds, people come to trust it, and Zhong Fu is the name the book gives that trust.
The Judgement runs roughly: Zhong Fu. Pigs and fishes. Good fortune. It is worth crossing the great water. It pays to hold to this.
The pigs and fishes are the point and they are usually explained away. They are the least tractable creatures in the Zhou farmyard, the ones with no obvious response to persuasion. The claim is that this quality reaches even them, which is a way of saying it does not work by argument. The word at the centre, fu, is written with a claw above a young bird, and it means both trust and the brooding of an egg. What is being described is something incubated rather than agreed.
The Image: wind over the lake. The noble person deliberates criminal cases and delays executions.
Wind moving over water moves the surface without touching the bottom, which is the image of something reaching all the way through. The conduct drawn from it is startlingly specific: judicial procedure, and the postponement of death sentences. Of everything the Wings could have recommended, they chose the one activity where being wrong is irreversible. The reasoning is that inner truth means holding a judgement open long enough to be sure of it, and the Image trusts that principle far enough to attach it to capital cases.
The name is two characters: centre, and fu. The second is the interesting one. It is written as a claw or hand over a young bird, and it carries the sense of hatching, brooding, and by extension of something reliable enough to be trusted. Trust in this hexagram is therefore not a decision. It is a thing kept warm until it comes out.
The figure supports the reading. Four solid lines, two at the bottom and two at the top, with a pair of broken lines in the middle: the hexagram has a hollow centre. Commentators from the Han onward read that emptiness as an unprejudiced heart, a middle with nothing already in it. The shape is also, plainly, an egg.
What the hexagram describes is influence that works because it is not being applied. The second line is its clearest statement: a crane calls in the shade and its young answers, without either bird being visible to the other. What changes with the question: asked whether someone can be persuaded, the hexagram says that persuasion is the wrong instrument. Asked whether something is trustworthy, it points at whether the thing goes all the way through or stops at the surface.
In a relationship question Zhong Fu is the good one, and it is worth saying so plainly. It describes trust that is mutual and unforced, and the second line gives the image: two birds calling to each other out of sight, one answering because it recognises the other.
The fourth line is the caution. The moon is nearly full, the team horse goes astray, and there is no blame. Nearly full is deliberate; the text avoids the completed moon throughout the book, because full is where decline starts. Something has to be given up here, and the loss of the paired horse is read as separating from a companion in order to keep the connection that matters. The hexagram makes no claim about what anyone else feels.
At work this is credibility rather than authority: being believed because your account of things has held up before. The Image's recommendation of careful deliberation and delayed sentence is close to a procedural instruction, and it applies to anything irreversible.
The third line is the honest counterweight. Someone finds a counterpart, and then beats a drum, stops, weeps, sings. It is a picture of a person whose state depends entirely on another party, and the text attaches no verdict at all. Trust and dependence share a border in this hexagram. Nothing here forecasts anything about your job, and the hexagram has no view on whether the people you rely on deserve it.
In a money question Zhong Fu is about credit in the older sense: whether your word is good, and whether the other party's is. It fits arrangements that run on trust rather than enforcement, which is a large share of ordinary financial life and almost none of the paperwork.
The hexagram has no view on amounts and gives no signal about any transaction. What it contributes is the sixth line, which describes a sound carrying up to heaven and calls persistence in it unfortunate. A reputation that has climbed higher than the substance underneath it is the failure named, and checking which of those you have is a matter for records rather than for the book.
Sit with the decision one more day before making it irreversible. The Image's instruction is to deliberate and to delay the sentence, and it attaches that to capital cases specifically, where being wrong cannot be undone. Apply it to whichever of your current decisions has that shape. If a day changes nothing, you have lost a day and gained certainty.
Yang in a yang place, correctly placed, at the bottom. Being prepared brings good fortune; if there are other designs, there is no rest. The line permits trust and immediately attaches a condition, which is that it has to be single. Divided intentions and this hexagram do not combine, and the text says so before anything else in the figure has happened. A strong line at the base has nothing yet to divide. Changing it produces Hexagram 59, Dispersion.
Yang in a yin place, not correctly placed, but central, and this is the most quoted line in the book. A crane calls in the shade; its young answers it. I have a good goblet; I will share it with you. Neither bird can see the other and the answer comes anyway. The line is the hexagram's whole argument, and the Great Treatise singles it out for extended comment. Changing it produces Hexagram 42, Increase.
Yin in a yang place, incorrectly placed, and the only line with no verdict at all. He finds a counterpart; now he drums, now he stops; now he weeps, now he sings. Four states in one sentence, all of them contingent on someone else. The text records the volatility and declines to judge it, which leaves the reader to decide whether this is connection or dependence. Changing it produces Hexagram 9, The Taming Power of the Small.
Yin in a yin place, correctly placed. The moon is nearly full; the team horse goes astray; no blame. Nearly full rather than full, because this book treats completion as the start of decline. The paired horse leaving is read as giving up a companion in order to hold to what matters more, and the verdict is the absence of fault rather than good fortune. Changing it produces Hexagram 10, Treading.
Yang in a yang place, central and correct, the ruling line. He possesses truth that links things together; no blame. The verb is the one used for binding or tying, and the line describes trust functioning as an actual connective rather than as a feeling. Even here the verdict is only the absence of fault, which is the hexagram declining to overstate its own subject. Changing it produces Hexagram 41, Decrease.
Yang in a yin place at the top, incorrectly placed, and the hexagram's failure. The sound of a bird carries up to heaven; persisting brings misfortune. A cock crowing is heard far beyond anything it can back up, and the image is of a reputation that has risen past the substance under it. Trust that has become noise is the last word here, and the top of the figure is where that reliably happens. Changing it produces Hexagram 60, Limitation.
The lower trigram is Dui, Lake; the upper is Xun, Wind. Wind over an open water surface, which moves what it touches without force. Both trigrams place a yielding line next to the centre of the figure, and the result is a hexagram with two broken lines at its middle: hollow where most are solid.
The nuclear hexagram, from lines two to five, is Hexagram 27, The Corners of the Mouth, the third figure in this stretch of the sequence to have it. Inside inner truth sits nourishment and dependency, which is a sharper observation than it first appears: trust and reliance are structurally the same relation seen from two ends.
The inverse is Zhong Fu itself. Turn the figure over and nothing changes, which puts it among the eight symmetrical hexagrams, so the King Wen pairing falls to its line-for-line opposite, Hexagram 62, Preponderance of the Small. Hollow centre against solid centre, and the two sit next to each other in the order for exactly that reason.
The Zhou oracle layer, roughly ninth century BCE, supplies the animals and the crane. The pigs and fishes of the Judgement have generated centuries of commentary, most of it trying to make them symbolic; the plainest reading is that they are the hardest creatures to reach, and the text is claiming reach.
The character fu is worth its own note. In the oracle bone script it shows a hand or claw above a child or a young bird, and its early senses cluster around hatching, capturing, and being reliable. The word runs throughout the book wherever trust is at issue, and this hexagram puts it in the title.
The second line has an unusual afterlife. The Great Treatise, one of the Ten Wings, quotes it in full and attaches an extended commentary on how words and actions carry beyond the person who makes them. That is one of the longest pieces of interpretation the Wings give to any single line, and it is why the crane passage is quoted more often than the hexagram.
In English, James Legge's 1882 translation is public domain and renders the name as Inmost Sincerity. Richard Wilhelm's 1924 German, into English by Cary Baynes in 1950, gives Inner Truth, which is the title in general circulation. Legge is closer to the Chinese; Wilhelm's phrase is better English and slightly more mystical than the original warrants.
Zhong Fu gets read as a hexagram about believing in yourself, and the English title helps. Inner Truth sounds like a private possession. The Chinese describes a relation: fu is trust between parties, and every line in the hexagram involves someone else. The crane has to be answered by its young for the line to mean anything, and a reading that turns this into self-confidence has removed the second bird.
The second misreading is the pigs and fishes, which commentators regularly convert into symbols of purity, sacrifice or the common people. The simplest reading is the one the text supports: these are the animals least susceptible to being talked round. The Judgement is making a claim about the limits of persuasion, and dressing the animals up loses it.
The third is what happens to the Image. Delaying executions is a specific procedural instruction about irreversible decisions made under uncertainty, and modern treatments soften it into a general recommendation of compassion. It is not about being kind. It is about the relationship between confidence and irreversibility, which is a harder and more useful thing for the reader to sit with.
