• Summary: Discover the meaning of the popular Chinese idiom 一本正经 (yī běn zhèng jīng), used to describe someone who appears very serious, solemn, or straight-faced. This comprehensive guide will teach you how to use this versatile term to describe a person's earnest expression, a deadpan sense of humor, or even a stuffy, overly formal attitude, complete with cultural context and practical examples.

• Pinyin (with tone marks): yī běn zhèng jīng
• Part of Speech: Chengyu (Idiom); can function as an adjective or adverb.
• HSK Level: HSK 5
• Concise Definition: To appear or be very serious, solemn, and proper in demeanor or expression.
• In a Nutshell: 一本正经 (yī běn zhèng jīng) paints a picture of someone with a “straight face” or a very earnest expression. Think of a stern-looking librarian, a judge in a courtroom, or a comedian delivering a punchline without cracking a smile. It's all about the outward appearance of seriousness. While it can describe genuine solemnity, it's often used with a touch of humor or irony to describe someone who is *acting* overly serious.

• 一 (yī): One; a single.
• 本 (běn): A measure word for books. It can also mean “root” or “origin.”
• 正 (zhèng): Proper, correct, upright, straight.
• 经 (jīng): A classic text, scripture, or sutra (like a religious or philosophical classic).

When combined, 一本正经 (yī běn zhèng jīng) literally translates to “one volume of a proper, classic text.” This creates a vivid image: a person whose expression is as serious and profound as an ancient, sacred book. Their demeanor is formal, upright, and without any hint of frivolity.

In Chinese culture, being 正经 (zhèngjīng)—proper, serious, and decent—is traditionally a virtue. It reflects a responsible and respectable attitude. The idiom 一本正经 builds on this, but its cultural significance lies in its flexibility. A useful Western comparison is the concept of being “deadpan” or “stone-faced.” However, they are not perfect equivalents.

• Deadpan: Almost exclusively used to describe a style of humor where jokes are told with a serious, emotionless expression to enhance the comedic effect.
• 一本正经 (yī běn zhèng jīng): This is broader. It can describe that same deadpan humor, but it can also describe genuine, non-humorous seriousness. For example, a teacher explaining a difficult concept to students might be praised for her 一本正经 attitude, showing she takes her role seriously. Conversely, it can be used with a slightly negative or teasing tone to tell someone they are being a “stick-in-the-mud” or too stuffy at a party.

The nuance comes from the context: is the seriousness appropriate and respectable, or is it out of place and therefore either funny or rigid?

This idiom is common in daily conversation, on social media, and in written Chinese. Its connotation depends entirely on the situation.

• Neutral/Positive Connotation: Used to describe a person who is genuinely focused, professional, or earnest in a situation that calls for it.
  • He's always very serious when it comes to his work.
• Humorous/Ironic Connotation: This is a very common usage. It's used to describe someone telling a joke or saying something absurd with a completely straight face. It highlights the contrast between the serious expression and the non-serious content.
  • He was spouting nonsense with a perfectly straight face.
• Slightly Negative/Teasing Connotation: Used to describe someone who is overly formal, rigid, or lacks a sense of humor. It's often used to encourage someone to relax.
  • Don't be so serious all the time, lighten up!

  • English: That little kid was scolding his puppy with such a serious face, it was adorable.
  • Analysis: Here, the humor comes from the inappropriate seriousness. A child acting like a stern adult is funny and cute.

  • Analysis: A neutral and appropriate use. Announcing exam results is a serious matter, so the teacher's expression is fitting for the occasion.

  • Pinyin: Pàiduì shàng dàjiā dōu yòu chàng yòu tiào, zhǐyǒu tā yī běn zhèng jīng de zuò zài jiǎoluò lǐ.
  • English: Everyone at the party was singing and dancing, only he sat in the corner looking all serious.

  • Analysis: A purely positive compliment. For a news anchor, a serious demeanor is a key part of their professionalism and credibility.

  • Pinyin: Wǒ zhǐshì kāi gè wánxiào, nǐ gàn嘛 yī běn zhèng jīng de fēnxī qǐlái le?
  • English: I was just joking, why are you analyzing it so seriously?
  • Analysis: This expresses mild frustration. The speaker is pointing out that the listener's serious reaction is inappropriate for a joke.
