Mandarin has separate words for the number 2 depending on context: 二 (èr) for counting and ordinals, 两 (liǎng) before measure words when you mean a pair of something. Mixing them up is a common early mistake, but the rule is straightforward once you hear it in conversation.
Use 二 (èr) when reciting numbers or forming ordinals like 第二 (dì èr) — the second. Use 两 (liǎng) whenever a measure word follows and you're talking about a quantity, as in 两个人 (liǎng gè rén) — two people. Counting to twenty? That's 二十 (èrshí). Ordering drinks? You need the measure-word version:
我要两杯茶。 (wǒ yào liǎng bēi chá.) — "I want two cups of tea."
Here 杯 (bēi) is the measure word for cups, so the numeral switches to 两 (liǎng). Remember 二 (èr) for numbers on their own and ordinals, and 两 (liǎng) whenever a measure word comes next.
This is a live conversation lesson: you talk out loud with AI teacher Mei Lin in real time, by voice rather than typing. Mei Lin corrects grammar and pronunciation in the flow of conversation and adapts to your level. The lesson targets this single grammar point — the contrast between 二 (èr) and 两 (liǎng) — and takes roughly 10 minutes. You'll practice choosing the right word across scenarios like ordering tea, counting, and talking about dates such as February, so the distinction becomes instinctive rather than memorized.
After this lesson, you can use the correct word for the number 2 in Chinese whether you're ordering drinks, counting to twenty, or talking about February.

二 (èr) is used for counting numbers and ordinals like 第二 (dì èr) — the second. 两 (liǎng) goes before measure words when you mean a quantity of something, like 两个人 (liǎng gè rén) — two people. The key sentence in this lesson, 我要两杯茶 (wǒ yào liǎng bēi chá), shows 两 (liǎng) because the measure word 杯 (bēi) follows.
