百口莫辩 (Bǎi kǒu mò biàn)

Basic Info

• Chinese Idiom: 百口莫辩 (Bǎi kǒu mò biàn)
• Pinyin: bǎi kǒu mò biàn
• Literal meaning: “A hundred mouths cannot argue it clear.”
  (百口 = a hundred mouths / a hundred voices; 莫 = cannot; 辩 = to argue / defend / explain)

The image is of someone with a hundred mouths to speak – and still being unable to clear their name.

Figurative Definition

It describes a situation in which someone is wrongly accused, misunderstood, or trapped in suspicion – and cannot defend themselves no matter how much they explain. Even with a hundred mouths, they could not speak enough to prove their innocence. It conveys a deep sense of helplessness, injustice, and frustration in the face of accusations that cannot be refuted.

It often implies that the circumstances, the evidence, or public opinion are stacked against the person, so that truth and explanation are useless.

In short: so completely unable to clear oneself that even a hundred mouths would not be enough.

Cultural & Historical Origin

This idiom comes from a letter by the Southern Song Dynasty poet Liu Guo (刘过, 1154–1206), in Written from the Jiankang Prison to Wu Jufu (《建康狱中上吴居父》):

“因一身于囹圄之中，不胜涂炭；被五木于拘挛之下，正值冰霜……虽有百口而莫辩其辜。”

“Confined alone in prison, unable to bear the suffering; bound in shackles under the frost… even with a hundred mouths, I could not argue away my guilt.”

Liu Guo wrote this letter from inside a prison, pleading his case to a powerful patron. He had been wrongly imprisoned, and the despair in his words is raw: even if he had a hundred mouths, he could not speak enough to prove his innocence. The phrase captured the agony of being trapped by false accusation – where the truth exists, but cannot be spoken loud enough to be heard.

The idiom reflects a recurring theme in Chinese literature and history: the helplessness of the falsely accused before an unjust system.

Key Lesson

Sometimes truth is not enough – and that is a profound injustice. The idiom honors the pain of the wrongly accused and reminds us to not rush to judgment. If someone is “百口莫辩,” it may not be because they are guilty – it may be because the situation has made explanation impossible. The wise person listens carefully, questions the evidence, and remembers that silence under accusation is not the same as guilt.

Cultural Note

In modern Chinese, “百口莫辩” is a strong, sympathetic, and often dramatic idiom. It appears in:

• Legal and social commentary – describing someone falsely accused with no way to clear their name.
• Personal expression – “我真是百口莫辩” (“I truly have no way to defend myself”), when someone feels unjustly suspected.
• Literature and film – portraying characters trapped by circumstance and rumor.
• Workplace and family disputes – when someone is blamed for something they did not do but cannot prove otherwise.

Its near-synonym is “有口难分” (yǒu kǒu nán fēn – “having a mouth but finding it hard to distinguish/clear oneself”). Its opposite is “一语道破” (yī yǔ dào pò – “to expose the truth in a single sentence”).
