学习学习？学学习习？学学习？Which one is correct?

In Chinese,words can be duplicated to indicate different meanings,but NOT ALL can be duplicated.

only VERB and ADJECTIVE.

Adj: AABB,can be used as predicative and adverb in a sentence,can NOT be used as an adjective.

It basically strengthens the degree,means very, equal to 很+adj.,so before AABB there should be no adv to repeatedly described how adj. it is.

The function of this structure is to make your sentence sound not so serious and plain,makes your sentence cute and relaxed.

她今天穿得漂漂亮亮的。(sounds relaxing)

她今天穿得很漂亮。（just telling a fact)

孩子们高高兴兴地去学校了。

*她穿着漂漂亮亮的衣服。❌

Verb: ABAB（verb that has two characters such as 学习，锻炼，认识，了解，调查 etc.）, indicates doing something for a while or casually,sometimes makes your sentence more polite，equal to V+一下儿.

AAB: separable verbs (聊天，考试，见面，结婚etc.) and one-character verb+object(看书，听音乐，洗衣服，做作业 etc.）

（ps：separable verbs are a special form of verb+object, I’ll explain it in another article)

周末的时候，我每天在家听听音乐，看看书，做做作业，学习学习汉语，锻炼锻炼身体，有时候去公园跑跑步，跟朋友见见面，聊聊天。

Exercise: Are the following sentences correct? If no,find out the mistakes.

1.我想去中国跟朋友见面见面。

2.这件衣服很便便宜宜，我很想买。

3.请你介介绍绍一下儿自己，好吗？

If you have any questions,feel free to contact me.

Best regards.
