百无禁忌 (Bǎi wú jìn jì)

Basic Info

Chinese Idiom: 百无禁忌 (Bǎi wú jìn jì)
Pinyin: bǎi wú jìn jì
Literal meaning: “A hundred [things] with no taboos.”
(百 = a hundred / all kinds; 无 = without; 禁忌 = taboos / prohibitions / things forbidden by custom or superstition)

Figurative Definition

It means there are no taboos, prohibitions, or restrictions whatsoever – one is completely free to act, speak, or do as one pleases, without regard for conventional rules, superstitions, or social niceties.

It can be used in three ways:

Positive / liberated – describing someone who is fearless, uninhibited, and free from superstition: “他百无禁忌，什么话都敢说。” (“He has no taboos – he dares to say anything.”)
Neutral / folk custom – a traditional phrase used to ward off evil spirits and bad luck: “百无禁忌，诸邪回避” (“All taboos are lifted; all evil spirits, retreat!”).
Slightly critical – describing someone who is reckless, tactless, or lacking in respect for norms: “他做事百无禁忌，得罪了不少人。” (“He acts without any restraint and has offended many people.”)

In short: no rules, no fears, no taboos.

Cultural & Historical Origin

This idiom comes from the Qing Dynasty folk proverb collection Yue Yan · Mingwu · Fengsu (《越谚·名物·风俗》 – “Yue Proverbs: Names and Things, Customs”) by Fan Yin (范寅):

“百无禁忌，诸邪回避。”

“All taboos are lifted; all evil spirits, retreat.”

In traditional Chinese folk belief, certain days, places, words, or actions were considered taboo (禁忌) – speaking a word could bring bad luck, moving in a certain direction could offend a spirit, or handling an object improperly could invite misfortune. The phrase “百无禁忌” was originally a protective incantation: by declaring that all taboos were lifted, it was believed that evil spirits would have no power and would retreat.

Over time, the phrase entered everyday language with two related meanings:

Freedom from superstition – “I don’t believe in any of that; for me, 百无禁忌.”
Fearless, unrestrained behavior – someone who acts without worrying about rules or consequences.

Key Lesson

Freedom is liberating – but it is not the same as recklessness. The idiom carries two sides:

Positive: It is good to be free from irrational fears and superstitions – to live boldly and without unnecessary self-restraint.

Warning: But “百无禁忌” can also mean ignoring all boundaries, including important ones – respect, ethics, and the feelings of others. True freedom knows the difference between liberation from superstition and disregard for others.

Cultural Note

In modern Chinese, “百无禁忌” is a common, colloquial, and flexible idiom. It appears in:

Everyday speech – describing someone who is uninhibited: “他是个百无禁忌的人。” (“He’s someone with no taboos.”)
Folk custom and festivals – the phrase is sometimes written on paper charms or spoken to ward off evil.
Humorous or self-deprecating contexts – “我今天百无禁忌，什么都说！” (“Today I have no taboos – I’ll say anything!”)
Mild criticism – when someone behaves without regard for social norms.

Its near-synonym is “无所忌讳” (wú suǒ jì huì – “having nothing to avoid or taboo”). Its opposite is “顾虑重重” (gù lǜ chóng chóng – “burdened with many worries and hesitations”).

It is worth noting that “禁忌” (jìn jì) is the standard modern Chinese word for “taboo,” used in psychology, anthropology, and everyday speech – and “百无禁忌” is one of its most common idiomatic expressions.
