Comparing "yihou" and "zhihou"

(Redirected from ASGC3SCN)

Both "以后" (yǐhòu) or "之后" (zhīhòu) mean "after," but there are a few tiny differences in usage.

Similarities between 以后 and 之后

Both can indicate another event happened after a specific time.

Structure

Subj. + Specified Time + 以后/之后 + Verb

In situations something happens after something else, you can use 以后. The stipulation with this is that "after WHAT" needs to be explicitly stated. That is, there has to be a "specified time" for 以后 to modify. Otherwise 以后 won't work in those sentences.

Examples

以后 and 之后 may be freely interchanged in any of the below sentences.

  • 下 过 雨 以后 空气 会 好 很 多 。Xià guo yǔ yǐhòu kōngqì huì hǎo hěn duō.After it rains, the air will be a lot better.
  • 结婚 之后 他们 有 了 两 个 宝宝 。 Jiéhūn zhīhòu tāmen yǒu le liǎng gè bǎobao.After getting married, they had two babies.
  • 等 我 涨 工资 以后 请 你 吃饭 。 Děng wǒ zhǎng gōngzī yǐhòu qǐng nǐ chīfàn.After I get a raise, I will treat take you out to eat.
  • 听到 这 个 消息 之后 ,我 高兴 得 一 晚上 没 睡 。 Tīngdào zhège xiāoxi zhīhòu, wǒ gāoxìng de yī wǎnshang méi shuì.After I heard this news, I was so happy I couldn't sleep the whole night.

Differences between 以后 and 之后

The key to understanding 以后 here is that if it doesn't come immediately after something else, then it's being used by itself. And when 以后 is used by itself, it doesn't mean "after;" it means "in the future."

以后 by Itself Means "In the Future"

Structure

以后 ,⋯⋯

Examples

  • 以后 再 也 不 来 这里 吃饭 了 , 又 贵 又 难吃 。 Yǐhòu zài yě bù lái zhèlǐ chīfàn le, yòu guì yòu nánchī.In the future I will never come to this place to eat again. It's expensive and the food is terrible.
  • 以后 我 可能 会 去 国外 上 大学 。 Yǐhòu wǒ kěnéng huì qù guówài shàng dàxué.In the future I might go to college abroad.
  • 以后 的 事情 以后 再 说 吧 。 Yǐhòu de shìqing yǐhòu zài shuō bā.We'll talk about future issues in the future.

之后 by Itself Means "After that"

Compared to 以后, 之后 is a little more flexible. Not only can it be used just like 以后, modifying the time, but it can also appear independently, meaning something along the lines of "after that." While 以后 must come after a specific time to mean "after," it cannot can stand by itself like this.

Structure

(Event 1 ,) 之后 + Event 2

Examples

  • 我 要 先 回家 把 东西 放 下 ,之后 去 咖啡店 找 你 。 Wǒ yào xiān huí jiā bǎ dōngxi fàng xià, zhīhòu qù kāfēidiàn zhǎo nǐ.I'm going to go home and drop my stuff off first, after that go to the cafe to look for you.
  • 去年 夏天 他 来 过 我 家 ,之后 再 也 没 见 过 他 。 Qùnián xiàtiān tā lái guò wǒ jiā, zhīhòu zài yě méi jiàn guo tā.Last summer, he came to my house. After that, I haven't seen him.
