HSK3 Grammar: Emphasising Earliness or Lateness — 就 vs 才 (jiù vs cái)
Use this to: Use this to show that something happened earlier or later than expected.
1. Grammar Introduction
就 (jiù) and 才 (cái) both connect a time/condition with an action, but they express opposite subjective judgements — the speaker's feeling about whether something happened early/easily or late/with difficulty.
就 — early, fast, easy, little, smooth: the speaker feels the action happened sooner, faster, or more easily than expected.
我六点就起床了。(Wǒ liù diǎn jiù qǐchuáng le.) — I got up as early as six o'clock.
才 — late, slow, hard, much, reluctant: the speaker feels the action happened later, more slowly, or with more effort than expected.
他八点才起床。(Tā bā diǎn cái qǐchuáng.) — He didn't get up until eight. (that late!)
Same fact, opposite feelings: 我三十分钟就到了 (only 30 min — so fast!) vs 我三十分钟才到 (30 whole minutes — so slow!).
就 — early / fast / easy / little / smooth
就: the speaker is impressed — sooner or easier than expected
就 comes between the time/condition and the verb. It ends with 了 because the result has been achieved. The speaker's tone is: "already / as early as / in just…"
Time / Condition+就+VP + 了
我六点就起床了。Wǒ liù diǎn jiù qǐchuáng le.I got up as early as six. (so early!)
我十分钟就吃完饭了。Wǒ shí fēnzhōng jiù chī wán fàn le.I finished eating in just ten minutes. (so fast!)

我一次就通过考试了。Wǒ yī cì jiù tōngguò kǎoshì le.I passed the exam on the very first try. (so easy!)
就 + 了 when the action is already completed. 就 without 了 when the action is still upcoming: 我十分钟后就到。(I'll be there in just ten minutes.)
才 — late / slow / hard / much / reluctant
才: the speaker is unimpressed — later or harder than expected
才 also comes between the time/condition and the verb. It does NOT take 了 at the end — the speaker's tone is: "not until… / it took that long / only after all that effort…"
Time / Condition+才+VP (no 了)
他八点才起床。Tā bā diǎn cái qǐchuáng.He didn't get up until eight. (so late!)

这几个苹果才十块钱。Zhè jǐ gè píngguǒ cái shí kuài qián.These few apples cost only 10 yuan! (surprisingly cheap)
✗ 他八点才起床了。— 才 does not take 了. The lack of 了 itself signals the speaker's dissatisfaction.
就 vs 才 — the same fact, opposite judgements
The clock doesn't change — only the speaker's feeling does
