Expressing earliness with "jiu"
Just as 才 (cái) can express lateness, 就 (jiù) can be used to indicate that something happened earlier than expected.
The pattern is as follows:
Subject + Time + 就 + Verb + Object
In English this might be expressed with "as early as", but usually it's not specifically marked.
- 我 昨晚 八 点 半 就 睡觉 了！I went to bed at half past eight last night.
- 我们 早上 九点 上课，可是 他 八点 就 来 了。We have class at nine in the morning, but he came at eight.
- 爷爷 每天 五点 就 起床 了。Grandpa gets up at five o'clock every day.
- 她 十八 岁 就 大学 毕业 了。She graduated from college when she was only 18 years old.
- 我 奶奶 五十 多 岁 就 去世 了。 Grandma passed away in her fifties.
From the example sentences it is clear that 了 naturally occurs with a verb used after 就. This is because verbs following 就 generally have the feeling of being completed.
