比 (bǐ): How to Say “…-er Than…” (Comparisons)
To compare two things, Chinese uses 比 (bǐ): Noun1 + 比 + Noun2 + Adjective = “Noun1 is more [adj] than Noun2” (我比他高 = “I'm taller than him”). The first noun wins; the adjective stays bare.
Why this trips learners up
The everyday way to compare two things in Chinese is 比 (bǐ), and it works a lot like English “than” — except the word order takes some getting used to. The pattern is Noun1 + 比 + Noun2 + Adjective: 我比他高 = “I'm taller than him”. 比 sits between the two things being compared, and whatever comes first wins — 小李比小张高 means Xiao Li is the taller one.
The big thing to unlearn: the adjective stays in its plain form. There's no “more”, no “-er”, and — crucially — no 很: 他比我高, never 他比我很高. Two more rules round it out. The adjective must be positive (to flip a comparison you swap the nouns — 他比我高, not 我比他不高), and 比 is only for things that differ — for “the same as” you switch to 跟…一样 (我跟他一样高), never 比…一样.
Want “even more”? Add 更 (gèng) before the adjective: Noun1 + 比 + Noun2 + 更 + Adj — 小李比小张更高 (“Xiao Li is even taller”), the sense being that Xiao Zhang is already tall and Xiao Li tops him. And for “much more”, don't reach for 很 — use a degree tail like 得多 or 多了: 这个城市比我的家乡大得多 (“much bigger”).

Common mistakes
Why it happens: No 很 inside a 比 comparison — the adjective stands bare. “He's taller than me” is 他比我高, never 他比我很高. For “much taller”, use a degree tail: 他比我高得多 / 高多了. (很 is for plain statements, not comparisons.)
Why it happens: The adjective has to be positive. You can't say “A 比 B not-tall” — 我比他不高 is wrong. To express the opposite, swap the two nouns and keep the positive adjective: 他比我高 (“he's taller than me”).
Why it happens: 比 is for things that DIFFER. For “the same as”, use 跟…一样, not 比 — “I'm as tall as him” is 我跟他一样高, never 我比他一样高. 比 = one is more; 一样 = they match.
Compare & contrast
| 比 — one is MORE (they differ) | 跟…一样 — they're the SAME | The difference |
|---|---|---|
| 我比他高。wǒ bǐ tā gāo. = I am taller than him | 我跟他一样高。wǒ gēn tā yīyàng gāo. = as tall as him | 我比他高 = “I'm taller than him” — one side wins. 我跟他一样高 = “I'm as tall as him” — dead level. |
| 这个比那个贵。zhège bǐ nàge guì. = this is dearer than that | 这个跟那个一样贵。zhège gēn nàge yīyàng guì. = this is as dear as that | 这个比那个贵 = “this is more expensive than that”. 这个跟那个一样贵 = “this is just as expensive as that”. |
