没有/不如: negative comparisons
没有 and 不如 are two ways to say A is less than B. A + 没有 + B + adjective means A is not as adjective as B, while A + 不如 + B means A is not as good as B and can end without an adjective.
Two structures to say X is less than Y:
1. A + 没有 + B + (那么/这么) + Adjective
> 这里的冬天没有北方冷。(Winters here aren't as cold as the north.)
2. A + 不如 + B + (+ Adjective)
> 她的成绩不如他好。(Her grades aren't as good as his.)
Key differences:
- 没有 = 'not as … as' — straightforward comparison
- 不如 = 'not as good as / inferior to' — implies B is the better option
Common mistake: Don't add 更 or 比 inside these structures.
❌ 她没有比他高。 ✅ 她没有他高。

Word by word
Each word in this pattern on its own: what it does here, the structure, three more examples, and the mistake to avoid.
没有 (méi yǒu)
Compares two things and says the first does not reach the level of the second.
Structure: A + 没有 + B + (那么/这么) + adjective
| Chinese | Pinyin | English |
|---|---|---|
| 这个房间没有那个房间大。 | Zhè ge fáng jiān méi yǒu nà ge fáng jiān dà. | This room is not as big as that room. |
| 我的汉语没有她那么好。 | Wǒ de hàn yǔ méi yǒu tā nà me hǎo. | My Chinese is not as good as hers. |
| 今天的作业没有昨天的多。 | Jīn tiān de zuò yè méi yǒu zuó tiān de duō. | Today's homework is not as much as yesterday's. |
Not: 今天没有比昨天冷。 Do not put 比 inside 没有; say 今天没有昨天冷。
没有 is also explained in: Comparison Sentences with 比 and 没有 (HSK 1) · The 有-Sentence: Possession and Existence (HSK 1) · 比 extended: degree & verb phrases (HSK 4).
不如 (bù rú)
'Not as good as'; B is the better one.
Structure: A + 不如 + B (+ adjective)
| Chinese | Pinyin | English |
|---|---|---|
| 看电视不如看书有意思。 | Kàn diàn shì bù rú kàn shū yǒu yì si. | Watching TV is not as interesting as reading. |

| 我觉得我不如他聪明。 | Wǒ jué de wǒ bù rú tā cōng ming. | I think I am not as smart as he is. |
Not: 我不如比他高。 不如 already compares, so do not add 比.
