Chinese Comparative Sentences: The Complete 比 (bǐ) Grammar Guide
Comparing two items is one of the most fundamental communicative tasks in any language:
- "This new electric car is faster than the previous model."
- "My older brother is three years older than me."
- "Today is even colder than yesterday."
In English, we form comparisons by adding "-er" to short adjectives ("cold" -> "colder") or preceding longer words with "more" ("more expensive").
In Mandarin Chinese, adjectives never change their form. Instead, Chinese relies on a dedicated comparative preposition: 比 (bǐ).
While the basic pattern is simple, beginners frequently commit one major grammatical mistake: adding degree adverbs like 很 (hěn) or 非常 (fēicháng) into the sentence. In Chinese comparative grammar, saying "A 比 B 很贵" is strictly ungrammatical!
Here is the golden rule:
In a standard 比 sentence (比字句 - bǐzìjù), compare two entities using A + 比 + B + Adjective. Do not use degree adverbs like 很 or 非常. To express how much they differ, place the difference (a bit, much, or an exact number) after the adjective.
Let us explore all the primary comparative structures, examine how to quantify differences, master negative comparisons with 没有 (méiyǒu), and review common HSK exam pitfalls. For foundational sentence structure, explore our Chinese grammar for beginners guide.

2. Basic Comparative Sentences: A + 比 + B + Adjective
The most basic way to state that entity A possesses a higher degree of a quality than entity B is:
- Formula: Subject A + 比 + Subject B + Adjective
Detailed Sentence Examples:
-
这家新开的生鲜超市的水果比街角便利店的新鲜。
- Pinyin: Zhè jiā xīn kāi de shēngxiān chāoshì de shuǐguǒ bǐ jiējiǎo biànlìdiàn de xīnxiān.
- English: The fruit at this newly opened fresh food supermarket is fresher than that at the corner convenience store.
- Quality Compared: 新鲜 (xīnxiān - fresh).
-
高铁商务座的车厢环境比二等座安静。
- Pinyin: Gāotiě shāngwùzuò de chēxiāng huánjìng bǐ èrděngzuò ānjìng.
- English: The cabin environment of high-speed rail business class is quieter than second class.
- Quality Compared: 安静 (ānjìng - quiet).
-
这款国产智能手表的电池续航时间比进口品牌长。
- Pinyin: Zhè kuǎn guóchǎn zhìnéng shǒubiǎo de diànchí xùháng shíjiān bǐ jìnkǒu pǐnpái cháng.
- English: The battery life of this domestic smartwatch is longer than the imported brand.
THE GOLDEN WARNING: The "No 很" Rule!
In an ordinary descriptive sentence, you say "他很高" (He is tall). But inside a 比 sentence, never use degree adverbs like 很, 非常, 特别, or 十分:
- Wrong: 高铁比大巴很舒适。 (Gāotiě bǐ dàbā hěn shūshì. - Strictly incorrect)
- Correct: 高铁比大巴舒适。 (Gāotiě bǐ dàbā shūshì. - Air-conditioned bullet trains are more comfortable than coaches.)
Because 比 already establishes the relative difference, adding an absolute degree modifier like 很 creates a grammatical collision.
3. Expressing Degrees of Difference
What if you want to specify how much A exceeds B? In Chinese, difference modifiers must always be placed after the adjective.
1. Slight Difference: 一点儿 (yìdiǎnr) / 一些 (yìxiē)
- Formula: A + 比 + B + Adjective + 一点儿 / 一些
Detailed Sentence Examples:
-
这件米白色羊绒毛衣的尺码比黑色那件大一点儿。
- Pinyin: Zhè jiàn mǐbáisè yángróng máoyī de chǐmǎ bǐ hēisè nà jiàn dà yìdiǎnr.
- English: The size of this beige cashmere sweater is slightly larger than the black one.
-

- Pinyin: Jīngguò xìtǒng yōuhuà hòu, xīn bǎnběn ruǎnjiàn de yùnxíng sùdù bǐ jiù bǎnběn kuài yìxiē.
- English: After system optimization, the running speed of the new software version is a bit faster than the old version.
2. Large Difference: 得多 (de duō) / 多了 (duō le)
- Formula: A + 比 + B + Adjective + 得多 / 多了
Detailed Sentence Examples:
-
市中心核心地段的写字楼租金比远郊产业园区高得多。
- Pinyin: Shìzhōngxīn héxīn dìduàn de xièzìlóu zūjīn bǐ yuǎnjiāo chǎnyè yuánqū gāo de duō.
- English: Office rents in the central downtown district are much higher than in the distant suburban industrial park.

- English: After listening to the specialist's detailed explanation, the patient's family felt much more relaxed.
- Result Complement Note: Notice 听完; see our guide to result complements.
3. Exact Numerical Difference: Number + Measure Word
- Formula: A + 比 + B + Adjective + Exact Amount

- English: Our company's R&D director is five years younger than the sales director.
4. Intensifying Comparisons: 更 (gèng) and 还 (hái)
If you want to say that B is already high in a quality, but A is "even more" pronounced, place 更 (gèng) or 还 (hái) directly before the adjective.
- Formula: A + 比 + B + 更 / 还 + Adjective
Detailed Sentence Examples:
-
北方冬天的室外气温虽然已经很低,但呼啸的西北风让体感温度比实际读数还要寒冷。
- Pinyin: Běifāng dōngtiān de shìwài qìwēn suīrán yǐjīng hěn dī, dàn hūxiào de xīběi fēng ràng tǐgǎn wēndù bǐ shíjì dúshù hái yào hánlěng.
- English: Although northern outdoor winter temperatures are already low, the howling northwest wind makes the perceived temperature even colder than the actual reading.

- English: The second alternative business proposal you proposed is even more feasible than the first proposal.
5. Negative Comparisons: 没有 (méiyǒu) vs. 不比 (bù bǐ)
When negating comparisons, English simply says "A is not taller than B." In Chinese, there are two distinct forms with very different conversational implications:
+-------------------------------------------------------------+
| NEGATIVE COMPARISON SHOWDOWN |
| |
| A 没有 B + Adj: A is NOT AS [adj] as B (A falls short) |
| A 不比 B + Adj: A is NOT MORE [adj] than B (Refuting claims)|
+-------------------------------------------------------------+
Pattern 1: A 没有 B + Adjective (Inferiority / "Not as... as")
This is the standard and most common negative comparison. It means that A does not reach the standard of B.
- Formula: A + 没有 + B + (这么 / 那么) + Adjective
Detailed Sentence Examples:
-
普通货运慢车没有磁悬浮列车那么平稳。
- Pinyin: Pǔtōng huòyùn mànchē méiyǒu cíxuánfú lièchē nàme píngwěn.
- English: Ordinary slow freight trains are not as smooth as maglev trains.
- Inferiority: The slow train falls well short of the maglev's smoothness.
-
我上个月写的初稿没有指导教授修改后的终稿那么严谨。
- Pinyin: Wǒ shàng ge yuè xiě de chūgǎo méiyǒu zhǐdǎo jiàoshòu xiūgǎi hòu de zhōnggǎo nàme yánjǐn.
- English: The initial draft I wrote last month is not as rigorous as the final draft revised by the advising professor.
Pattern 2: A 不比 B + Adjective ("Not more than" / Defending Equality)
不比 (bù bǐ) is not a neutral description. It is usually used in argumentative contexts to refute someone else's assertion and defend that A is at least equal to B.
Detailed Sentence Examples:
-
国产高端数码相机的成像传感器不比国外知名品牌差。
- Pinyin: Guóchǎn gāoduān shùmǎ xiàngjī de chéngxiàng chuángǎnqì bù bǐ guówài zhīmíng pǐnpái chà.

- Pinyin: Niánqīng chéngxùyuán de chuàngxīn nénglì bù bǐ zīshēn gōngchéngshī ruò.
- English: Young programmers' capacity for innovation is not inferior to that of senior engineers.
6. Comparing Actions with Verbs (The 得 Bridge)
When comparing how well, fast, or frequently someone performs an action, you must use the complement of degree marker 得 (de).
There are two valid word orders:
Word Order A: Subject A + Verb + 得 + 比 + Subject B + Adjective
- 他跑得比我快。
- Pinyin: Tā pǎo de bǐ wǒ kuài.
- English: He runs faster than I do.
Word Order B: Subject A + 比 + Subject B + Verb + 得 + Adjective
- 他比我跑得快。
- Pinyin: Tā bǐ wǒ pǎo de kuài.
- English: He runs faster than I do.
Detailed Sentence Examples:
-

8. Common Mistakes to Avoid
Mistake 1: Inserting 很 into a 比 Comparison
- Wrong: 他的车比我的车很大。
- Pinyin: Tā de chē bǐ wǒ de chē hěn dà. (Incorrect)
- Why it fails: Absolute degree adverbs cannot appear in 比 sentences.
- Correct: 他的车比我的车大。 (or 他的车比我的车大得多。)
- Pinyin: Tā de chē bǐ wǒ de chē dà de duō.
- English: His car is much bigger than mine.
Mistake 2: Placing the Difference Before the Adjective
In English, we say "two kilograms heavier." In Chinese, the measure comes after the adjective.
- Wrong: 这个包裹比那个包裹两公斤重。
- Pinyin: Zhè ge bāoguǒ bǐ nàge bāoguǒ liǎng gōngjīn zhòng. (Incorrect word order)
- Why it fails: The numerical difference must follow the adjective.

- Pinyin: Zhè ge bāoguǒ bǐ nàge bāoguǒ zhòng liǎng gōngjīn.
- English: This parcel is two kilograms heavier than that parcel.
Mistake 3: Using 不比 for Simple Inferiority

- Natural Choice for "Not as... as": 纸质书没有电子书方便。
- Pinyin: Zhǐzhì shū méiyǒu diànzǐshū fāngbiàn.
- English: Paper books are not as convenient as e-books.
9. Frequently Asked Questions
Can 比 sentences compare two verbs?

- Pinyin: Wǒ bǐ yǐqián gèng xǐhuan zài ānjìng de túshūguǎn lǐ xuéxí.
- English: Compared to before, I prefer studying in a quiet library even more.
How does 一样 (yíyàng) fit into comparisons?
While 比 expresses difference, 一样 expresses equality:
- Formula: A + 跟 / 和 + B + 一样 + Adjective
- Example: 这台笔记本电脑和我那台一样轻 (This laptop is just as light as mine).
