a verbal measure word.

Structure
Quantitative complements usually appear after the verb denoting the action to which they refer.
With an aspectual particle
If the verb is used with the aspectual particles le 了 or guo 过/過 , the quantitative complement always comes after these particles.
With an object
The position of an object in sentences with quantitative complements depends on the type of the object.
A noun object (represented by a common noun or an abstract noun) is usually placed after the complement.
A pronoun object is always placed before the complement.
The object denoting a specific person or place can be placed either before or after the complement.
The object can also be placed at the beginning of the sentence.
The choice of the appropriate sentence pattern depends on the context. Objects that have already been mentioned in the utterance tend to appear before the subject. In contrast, objects mentioned for the first time more often come after the complement.
With adverbs
In sentences with quantitative complements adverbs (including adverbs of scope which refer to the number of repetitions of the action) are usually placed before the verb.
Questions
Questions about the number of the repetitions of an action are formed by replacing the numeral in the frequency phrase with the appropriate interrogative pronoun: jǐ 几/幾 ‘how many’ or duōshao 多少 ‘how many’. For example:
Negation
In the negative sentences with quantitative complements the negation adverb méi 没/沒 is placed before the verb.
Such sentences are usually used to correct wrong or inaccurate information about the number of repetitions of the activity.
Functions
Quantitative complements are used to express the number of times the action takes place.
