When to use Duration and Frequency

Duration usually follows the verb or object structure. 次 counts how many occurrences of an action happened.

我去过北京三次。

I have been to Beijing three times.

她每天跑步。

She runs every day.

请等五分钟。

Please wait five minutes.

这个电影我看了两次。

I watched this movie twice.

Common traps

  • Do not confuse a time point with a duration.
  • 次 counts events, not objects.
  • Duration placement can change when the object is long; keep examples short at first.
