中孚Zhong Fu.Inner Truth.
Wind moves above Lake: influence travels across an open centre and receives a genuine response. Zhong Fu concerns trustworthiness rooted so deeply within that words, agreements and actions carry conviction without coercion.
Make the inside and outside answer to the same truth.
Zhong Fu is not simply honesty as confession. It is fidelity between intention, speech and conduct. The open central lines suggest receptivity, while the firm lines around them provide the structure that keeps openness from becoming credulity.
Its influence reaches even “pigs and fishes”—beings conventionally regarded as difficult to influence—because genuine trust does not depend on performance. It creates the confidence needed to cross difficulty, make commitments and judge with humanity.
Wind above. Lake below.
Lake opens and responds; Wind penetrates and carries influence. Two yielding lines form a receptive centre, enclosed by firmness above and below.
Credibility reaches where force cannot.
The governing proposition
中孚：豚魚吉，利涉大川，利貞。
Inner Truth. Pigs and fishes: good fortune. It is beneficial to cross the great river. Constancy is beneficial.
An open vessel crosses danger
中孚，柔在內而剛得中。說而巽，孚乃化邦也。豚魚吉，信及豚魚也。利涉大川，乘木舟虛也。中孚以利貞，乃應乎天也。
Yielding is within and firmness gains the centre. Joy and gentle penetration allow trust to transform the state. Sincerity reaches even pigs and fishes; the hollow wooden vessel makes the great crossing possible.
Examine judgment with humanity
澤上有風，中孚；君子以議獄緩死。
Wind above the Lake: Inner Truth. The noble one deliberates over legal cases and delays executions.

Meeting an adversaryNow beating drums, now stopping; now weeping, now singing · Changes to 9 小畜
六三：得敵，或鼓或罷，或泣或歌。

The moon is nearly fullThe paired horse is lost; no blame · Changes to 10 履

Trust binds firmlyNo blame · Changes to 41 損

A cock’s call rises to heavenPersistence brings misfortune · Changes to 60 節
上九：翰音登于天，貞凶。
A loud claim cannot substitute for grounded truth. When reputation rises beyond substance, maintaining the performance becomes dangerous.
小象傳 · 翰音登于天，何可長也. How could a cock’s call rising to heaven endure?
Build trust through correspondence between promise, evidence and action.
Work and leadership
Make commitments that can be verified, share value and allow scrutiny. Credibility becomes institutional when leaders practise the standards they communicate.
Relationships
Listen without surrendering discernment. Trust grows through repeated correspondence between what is felt, said and done—not through intensity alone.
Timing and decisions
Before a consequential crossing, test the centre: Is the motive stable? Are incentives aligned? Will the commitment survive when no one is watching?
Zhong Fu is aligned when sincerity produces reliable resonance.
Aligned expression
- Speech and conduct reinforce each other.
- Openness is supported by sound boundaries.
- Trust survives verification and difficulty.
- Judgment includes both evidence and humanity.
Distorted expression
- Emotional intensity is mistaken for truth.
- Hidden agendas fracture apparent agreement.
- Credibility depends on performance or status.
- Claims rise higher than the evidence supporting them.
