The frequency complement (1)
In Chinese “number + 次 (cì)” follows the verb and states how many times the action happened.
Basic structure
Verb + number + 次
… times.
Examples
我想去中国，虽然去过一次，但是很想再去一次
去 + 过 + 一次
go + experience + once
再 + 去 + 一次
again + go + one more time
去过一次qù guo yí cìhave been once
再去一次zài qù yí cìgo one more time
Here 一次 states how many times the action happened.
With an object
If the verb takes an object that is a person's name or a place name, the object may stand either before or after the frequency complement.
Verb + object + number + 次
or
verb + number + 次 + object
安妮去过一次北京
安妮ĀnnīAnnie

一次yí cìonce
北京BěijīngBeijing
Here 北京 is a place name, so it follows 一次.
李文见了杨同乐两次
李文Lǐ WénLi Wen

杨同乐Yáng TónglèYang Tongle
两次liǎng cìtwice
Here 杨同乐 is a person's name, so it precedes 两次.
Quick rule
Verb + number + 次
Meaning: it states how many times the action happened.
去一次 — go once
见两次 — see twice
When the object is a person's name or a place name:
Verb + object + number + 次
or
verb + number + 次 + object
去过一次北京 — has been to Beijing once
见了杨同乐两次 — saw Yang Tongle twice
