A word or phrase of time follows the verb and states how long the action or state lasted.

When the verb also has an object
If the verb takes an object, the object can sit in either of two places.
1. If the object is a thing, it usually follows the duration.
Verb + duration + object

I watched television all evening.
看了 + 一个晚上 + 电视
watched + one evening + television
看了watched
一个晚上one evening

2. If the object is a person or a pronoun, it usually precedes the duration.
Verb + object + duration

Repeating the verb
When the verb has an object, the verb may be repeated with the duration after the repeat.
Verb + object + verb + duration

With separable verbs
If the verb is a 离合词 (separable verb), its first half is repeated when the duration is added.

“了……了” — when the action is still going on
When 了 appears both after the verb and at the end of the sentence, the action is still going on.
Verb + 了 + duration + ... + 了
Meaning: has been doing … for …
他写了半个小时汉字了。
He has been writing characters for half an hour.
写了 + 半个小时 + 汉字 + 了
wrote + half an hour + characters + 了
the action began earlier;
and is still going on.
陈天中跑步跑了两个小时了。
Chen Tianzhong has been running for two hours.
跑步 + 跑了两个小时 + 了
run + ran for two hours + 了
Here too the running is still going on.
Quick rule
Plain duration: verb + duration
Object is a thing: verb + duration + object
Object is a person or pronoun: verb + object + duration
With the verb repeated: verb + object + verb + duration
Still going on: verb + 了 + duration + ... + 了
has been doing … for …
