01 What Are Chinese Idioms? Chengyu (成语) Meaning Explained

The Chinese word for idiom, 成语 (chéngyǔ), can be translated literally as "already made words" or "formed words." In practice, chengyu are fixed expressions whose wording never changes.

These phrases were woven together over thousands of years from ancient myths, folktales, poetry, and philosophical writing, including the sayings of thinkers like Confucius. In this sense, chengyu are a living testament to the longevity and continuity of Chinese literature and culture.

How many Chinese idioms are there?

Depending on which dictionary you consult, there are between 5,000 and 20,000 Chinese idioms. Although most are centuries old, a surprising number are still used in contemporary Mandarin every day.

New idiom-like expressions also continue to appear in Chinese online communities. You can explore these modern coinages in our guide to Chinese internet slang.

Why are most Chinese idioms four characters long?

The majority of chengyu are composed of exactly four characters. When an idiom refers to a myth or historical incident, those four characters succinctly paraphrase the most important elements of the story, acting as a kind of mnemonic device.

Over the course of their education, elementary and high school students in China memorize thousands of these idioms. For foreign learners, even a small working set of chengyu adds nuance that everyday vocabulary can't provide.

03 How Chinese Idioms Are Used in Everyday Conversation

After a few months of study, learners often grow confident in basic conversation. Then, suddenly and without warning, they're confronted by a curious phenomenon: the Chinese idiom.

Whether used to emphasize a point in an argument, encourage a friend not to quit, or show off knowledge of the classics, chengyu come up daily. If you don't learn at least a few, many of the nuances of conversation will pass you by.

Chinese people often use Chinese idioms in everyday conversation.

人山人海 (rénshān-rénhǎi): "people mountain, people sea"

Imagine a student complaining to a Chinese colleague that the cafeteria is too crowded to get lunch in time. Her colleague nods and exclaims, "人山人海" (rénshān-rénhǎi).

Character for character, the phrase translates to "people mountain, people sea." Thinking she has misheard some local slang, the student asks her colleague to repeat it, only to end up more confused than before.

In fact, 人山人海 simply means "a sea of people" or "huge crowds." Her colleague was commiserating: "Yeah, the cafeteria is packed today."

人山人海 (rénshān-rénhǎi) is the perfect idiom to use when talking about crowds.

Why context matters when learning chengyu

A good Chinese dictionary app like Pleco will define 人山人海 as "huge crowds; a sea of people; a multitude." Once you know the definition, the idiom suddenly comes in handy everywhere, from packed metro stations to holiday crowds.

Not all chengyu are this transparent, however. Because their source material is usually classical Chinese, idioms often use rare characters, or use familiar common Chinese characters in ways that defy modern Chinese grammar.

Since most chengyu come from classical Chinese, they can be hard for modern learners to understand without context.

04 Chinese Idiom Stories From History: 破釜沉舟 and the Fall of the Qin

The chengyu 破釜沉舟 (pòfǔ-chénzhōu) literally means "break the cauldrons and sink the boats," while 以一当十 (yǐyī-dāngshí) literally means "one against ten." Used in isolation, both would be nearly impossible to decipher.

With a little historical background, however, their meanings suddenly reveal themselves. Both idioms come from one of the most famous battles in Chinese history.

Having a basic knowledge of Chinese history can make many Chinese idioms easier to understand.

The story behind 破釜沉舟: Xiang Yu's rebellion against the Qin dynasty

In the bitterly cold winter of 207 BC, the commander Xiang Yu led a ragged force of roughly 50,000 rebels. Their enemy was the seemingly invincible imperial army of the Qin dynasty, more than 300,000 strong under general Zhang Han.

To the shock of his lieutenants, Xiang Yu chose to attack rather than wait to be hunted down. After crossing the Yellow River, he ordered his troops to sink their own ships, smash their cooking pots, and carry only three days of provisions.

Ancient Chinese soldiers from the Qin dynasty era
The stories behind some Chinese idioms can be traced all the way back to the Qin dynasty.

The message was clear: victory or death. In the nine engagements that followed, Xiang Yu's soldiers were each said to "have taken on ten foes," and after losing more than 100,000 men, Zhang Han's imperial troops turned and fled.

What 破釜沉舟 and 以一当十 mean today

With Xiang Yu's victory in mind, the meaning of 破釜沉舟 becomes clear: "to reach a point of no return; to stake everything on success." It is the Chinese equivalent of "burning your boats."

Equally self-evident is 以一当十 (yǐyī-dāngshí): "every one of us is worth ten ordinary people." Learning a little Chinese history is one of the best shortcuts to mastering chengyu.

06 A Famous Five-Character Chinese Idiom: 山高皇帝远

Although most chengyu are four characters long, some are not. One common favorite is five characters long: 山高皇帝远 (shān gāo, huángdì yuǎn), "the mountains are high and the emperor is far away."

You may also encounter the even more widespread variant 天高皇帝远 (tiān gāo, huángdì yuǎn), "heaven is high and the emperor is far away." Both versions express the same mischievous idea.

The closest English equivalent might be "when the cat's away, the mice will play," though this doesn't quite capture the depth of mischievousness involved. It's used whenever people relax the rules because authority is out of sight.

When to use 山高皇帝远

  • When you're having a girls' night out and everyone begins to gossip about their boyfriends: 山高皇帝远
  • If you're on an international business trip and a colleague brazenly uses the company card to buy drinks: 山高皇帝远
  • When you catch grandpa having a secret smoke behind the house, he smiles and says... yes, you guessed it: 山高皇帝远

Despite their rarified origins, Chinese idioms are very useful for describing everyday situations.

07 How to Learn Chinese Idioms (and Why They Matter for the HSK)

The more idioms and sayings you learn, the more natural your spoken and written Chinese will become. Chengyu knowledge is also tested on Chinese proficiency exams like the HSK, and it's essential if you want to pass HSK 6.

A few practical tips: learn the story behind each idiom rather than memorizing characters in isolation, and start with high-frequency chengyu like the ones in this article. Folding a few idioms into your weekly Chinese study plan is far more effective than cramming hundreds at once.

Be careful, though: using a chengyu in the wrong context can cause confusion or unintended laughs. If you've ever wondered whether Chinese is hard to learn, idioms are a perfect example of something that seems daunting at first but becomes deeply rewarding with practice.

Beyond chengyu, Chinese contains a wealth of sayings on every topic, from proverbs about learning to proverbs about family. Each one you master deepens both your language ability and your cultural understanding.
