In the beginning, many Chinese learners struggle to see the difference between two phrases: 的时候 (de shíhou) and 以后 (yǐhòu).
Let’s have a look at how the meaning of one sentence changes depending on which word we use in it.
Yesterday, while I was doing homework, she was washing the clothes.⠀
Yesterday, after I finished homework, she went to wash the clothes.⠀
From this example, we can see that the meanings of these two words are not the same at all!
In More Detail
1️⃣ Use 的时候 to stress that 2 actions are happening at the same time. Or during a specific period of time:
It started raining at 3 o’clock.⠀
2️⃣ Use 以后 to show a sequence of two actions, happening one after the other.
Also, use it to show that event happens after [a certain point in time]:
It might rain after 3 o’clock.
It’s not so difficult as soon as you get the right examples to compare these two words, is it?
Now try to finish the sentences by yourself!
