The word 'wanna' is incorrect grammatically. It is equivalent to 'want to.' When combined with the word 'I' it helps communicate something you want to do. 'wanna'这个词是不正确的语法，它相当于'want to'，当和单词'I'结合的时候，它就帮助沟通你想要做的事情。

Here are some examples: 这里有一些例子： 

"I wanna talk."

 我想要聊天。

"I wanna search for a job."

 我想要找一份工作。

"I wanna order some food."

 我想要订餐。

"I wanna marry her."

 我想要娶她。

"I wanna listen to that song."

 我想要听那首歌。

By adding the word 'don't' you can change the meaning of what you are saying to something you 'want' to do to something you 'do not' want to do. 通过加'don't'这个词你可以把你要说的你想做的某些事情变成你不想做的事情。
