有案可稽

You’ll usually see this phrase acting as a descriptive tail for a statement of fact. You state something bold, and then you follow it up by saying that this thing is 有案可稽. For example, if you're claiming that your company's sales doubled last year, you’d say those figures are 有案可稽. It functions as a predicate or an adjective-like phrase. You can say "某事 (Something) 有案可稽." In modern times, this isn't just for dusty paper files anymore. You can use it for blockchain transactions, email threads, or even public social media posts that haven't been deleted yet. Imagine you're arguing with a friend about who won a bet three years ago. If you still have the WhatsApp message, you can smugly tell them the result is 有案可稽. It adds a layer of "don't even try to argue with me" to your speech. It’s perfect for formal reports, but it’s also great for being a "know-it-all" in a way that sounds impressively educated. Pro tip: if you use this in a job interview while discussing your achievements, you’ll sound like a person who values data and integrity. Just make sure the records actually exist, or you’ll look like a clown when they ask to see them!

This is a C1-level phrase, so it’s definitely on the "smart person" side of the spectrum. It sits comfortably in the formal and neutral zones. You won't hear teenagers shouting this at each other while playing League of Legends—unless they are very, very strange teenagers. However, it’s not so formal that it’s restricted to 18th-century poetry. You’ll find it in news articles, business reports, legal documents, and serious non-fiction books. If you’re writing an email to your boss or a client, this phrase is your best friend. It makes you sound authoritative and grounded. In casual settings, it can be used ironically or for emphasis. If your friend always forgets to pay you back for bubble tea, saying "our debts are 有案可稽" (referring to your Venmo history) is a hilarious way to use a high-level idiom for a low-level problem. It’s like wearing a tuxedo to a taco stand—overkill, but stylish in its own way. Generally, the more important the stakes, the more natural this phrase feels.

Let’s look at how this shows up in the wild. Imagine a news report about a historical building. The reporter might say the building’s history is 有案可稽, meaning there are government records dating back centuries. Or think about a corporate audit. The auditor will state that all expenses are 有案可稽, which is a fancy way of saying "I checked the receipts and they actually match." In the world of social media, if a celebrity gets "canceled" for something they said ten years ago, a blogger might write that their past remarks are 有案可稽. It’s the ultimate "the internet never forgets" phrase. Even in sports, if a player breaks a record, the commentator might say their career stats are 有案可稽 in the official league books. It’s used whenever we need to bridge the gap between "I think so" and "I know so because I have the evidence." It’s the difference between a rumor and a verified Wikipedia entry. If life were a video game, 有案可稽 would be the achievement you unlock only after you've saved every game state perfectly.

Use this when the stakes are high and you need to prove a point. It’s perfect for business negotiations where you need to reference past agreements. It’s great for academic writing when you’re citing sources that are indisputable. Use it in legal contexts or when discussing government policies. Basically, if there is a literal file (digital or physical) that backs you up, this is your phrase. It’s also very effective in arguments where the other person is gaslighting you. If they say, "I never said that!" and you have the email, telling them the fact is 有案可稽 is a polite but firm way of saying "Check your inbox, buddy." It’s also useful for historical discussions. If you’re talking about your family tree or a local legend, saying it’s 有案可稽 separates fact from folklore. It’s the verbal equivalent of pointing at a signature on a contract. Use it when you want to be taken seriously.

Don't use this for things that are purely subjective or emotional. You can't say "My love for you is 有案可稽"—that sounds like you have a spreadsheet of your feelings, which is more creepy than romantic. Avoid using it for trivial, daily stuff. If you tell your roommate that your turn to do the dishes is 有案可稽, they’ll probably roll their eyes at your dramatic vocabulary. Also, don't use it if the "records" are just your own memory. That’s the opposite of what the phrase means! If there’s no physical or digital proof, you’re just lying in a very sophisticated way. It’s also not suitable for slang-heavy, super casual chats with friends unless you’re being intentionally funny. Using it in a text like "Hey, u want pizza? It's 有案可稽 that Friday is pizza night" is just... weird. Keep it for when you need to sound like a professional adult who doesn't play games with facts.

The most common mistake is confusing the last character 稽 (jī) with similar-looking characters like 和 or 积. People also sometimes try to say 有案可查 (yǒu àn kě chá). While 有案可查 is actually a valid and very similar phrase, 有案可稽 sounds slightly more literary and formal. Another mistake is using the wrong word order, like 案有可稽. That just sounds like Yoda trying to speak Chinese. Some learners also use it as a verb, like "I will 有案可稽 this." Nope! It’s a description of a state, not an action you perform.

Don't be the person who tries to sound smart but trips over the characters. Practice writing 稽—it’s got a lot of strokes, but it’s worth the effort for that C1 street cred!

While 有案可稽 is the gold standard, you might hear 有据可查 (yǒu jù kě chá), which means "has evidence available to check." It’s a bit more common in everyday speech. Then there’s 查有实据 (chá yǒu shí jù), which means "investigation has found solid evidence." This one is even more intense—it implies the checking has already happened and the proof is definitely there. For the opposite, use 无据可查 (wú jù kě chá)—meaning there's absolutely no trail to follow. It's what people say when a mystery remains a mystery. In modern internet slang, people just say "有图有真相" (yǒu tú yǒu zhēn xiàng), which means "have pictures, have the truth." It's the "pics or it didn't happen" of the Chinese web. While 有案可稽 is for lawyers and historians, "有图有真相" is for Reddit and Weibo. Knowing these variations helps you pick the right "evidence" phrase for the right crowd. You wouldn't use internet slang in a court of law, and you wouldn't use 有案可稽 to prove you actually saw a UFO on TikTok.

Is this phrase too formal for an email to a colleague?

Not at all! It makes you sound organized and reliable. If you're discussing a project's history, it's actually very professional. Just don't use it if you're just asking where the stapler is.

Can I use it for digital records?

Absolutely. In fact, most things 有案可稽 these days are digital. Whether it's a PDF, a database entry, or a saved chat, it all counts as an "案" (record) in the modern world.

What's the difference between this and 真凭实据?

真凭实据 emphasizes that the evidence is "real and solid," focusing on the quality of proof. 有案可稽 emphasizes the existence of a "record or file," focusing on the fact that it was officially documented somewhere. One is about the "what," the other is about the "where."

Does it have a negative connotation?

Not inherently. It’s a neutral term. However, it’s often used in investigations or arguments, so it can feel a bit "serious." It’s like a flashlight—it just shows what’s there, whether it’s a gold bar or a skeleton in the closet.
