Summary: 一清二楚 (yīqīng'èrchǔ) is a common and highly useful Chinese idiom (chengyu) that means “crystal clear” or “perfectly clear.” It's used to describe a situation, explanation, view, or understanding that is completely free of ambiguity or confusion. Whether you're confirming you understand instructions or describing a breathtakingly clear view, learning 一清二楚 will make your Chinese sound more expressive and authentic.
Core Meaning
Pinyin (with tone marks): yīqīng'èrchǔ
Part of Speech: Idiom (Chengyu); can function as an adjective or adverb.
HSK Level: HSK 5
Concise Definition: To be perfectly clear, unambiguous, and easy to understand.
In a Nutshell: Think of the English phrase “crystal clear.” That's the core feeling of 一清二楚. It’s a powerful way to express that something is completely transparent and leaves no room for doubt. You use it when a simple “clear” (清楚, qīngchu) isn't strong enough. It emphasizes total, absolute clarity.
Character Breakdown
一 (yī): One, first.
清 (qīng): Clear, distinct, clean. Think of clear water (清水, qīngshuǐ).
二 (èr): Two, second.
楚 (chǔ): Clear, neat, orderly. This character also means “clear” and is often paired with 清 to intensify the meaning.
The structure “一…二…” is a common rhythmic pattern in Chinese idioms that adds emphasis. By pairing two synonyms for “clear” (清 and 楚) with numbers, the idiom effectively says, “It's clear in the first place, and it's clear in the second place,” creating a powerful sense of completeness. It means everything about the matter is thoroughly and completely clear.
Cultural Context and Significance
一清二楚 reflects the value of lucidity in communication, especially when it matters most. While Chinese culture is known for indirectness in many social situations, idioms like this one provide a tool for demanding or declaring absolute clarity when necessary, such as in business, law, or education. Using it signals, “There should be no misunderstanding about this.”
Comparison to Western Culture: The English phrase “crystal clear” is a very close equivalent. However, the structure of 一清二楚 gives it a slightly more formal and emphatic tone. It’s not just an adjective; it feels like a definitive statement. While an American might say, “Let me be clear,” a Chinese speaker might state a point and then add, “这件事我希望大家都能一清二楚” (I hope everyone is crystal clear on this matter), using the idiom to punctuate the importance of the statement.
Practical Usage in Modern China
In Conversation: It's frequently used to confirm understanding. For example, after receiving instructions, you might say “好的，一清二楚了” (Okay, it's crystal clear now).
Describing Situations or Information: You can use it to describe anything that is easy to comprehend, like a well-organized report, a clear explanation, or even the state of a financial account. “His explanation made the whole process crystal clear.”
As an Adjective vs. Adverb:
As an adjective: 他的解释是一清二楚的。(His explanation was crystal clear.)
As an adverb: 他把事情解释得一清二楚。(He explained the matter crystal clearly.) This “得” (de) structure is very common.
Connotation: The connotation is overwhelmingly neutral to positive. Clarity is almost always a desirable quality.

`一清二楚 (yīqīng'èrchǔ)` is an idiom that adds significant emphasis. It means “PERFECTLY clear” or “ABSOLUTELY clear.” Use it when you want to stress the total lack of confusion.
