How do you say "You mean ...?" to respond to what you don't understand enough?
So how can I express "You mean ...?" in Mandarin, to ask what they mean?


"你的意思是XXX？" means you are making a guess, and asking for a confirmation

If you don't understand a person's single statement, the simplest way to ask for clarification is "你的意思是...?" (you meant....?) and let that person explain. or you can say "这是什么意思？" (what does it mean?)

If you don't understand a person's speech, you can just say "我不知道你在说什么" (I don't know what are you saying)  , "我不明白你在说什么" or 我听不懂你在说什么" (I don't understand what you are saying)

It is the perfect response to the speech in your example


  Come back to "你的意思是XXX？" (you meant XXX?) 


The usage are the same in Chinese and English

Example: 

A: "我讨厌生鱼!" (I hate raw fish!)

B: "你的意思是你讨厌吃鱼生?" (you meant you hate eating Sashimi?) 

It can't be you hate living fish, right?


  "你的意思是XXX?" can be replaced with  "你是指XXX" (are you referring to XXX?)
