Yes, the way you have used "really" in these sentences is correct. You have really done a good job :-)

Tanvir:

You have a question about my favorite word.

The adverb "really" is really, really (= very) interesting. Really! ( = Believe me!)

Sometimes, it is very difficult to know what it is referring to.

Here are two examples similar to yours:

1. I really do not speak Chinese. = Believe me. I am telling you the real truth. I do not speak Chinese.

2. I do not really speak Chinese. = Yes, I can say 50 sentences in Chinese, and I can recognize 250 characters. But it would be a lie to say that I can actually speak Chinese.

I really liked your question.  (This time, "really" probably just emphasizes the verb "liked.")

Really, I liked your question; I liked your question, really! ( = Believe me!)

nice... thanks for sharing... ^^

Hi, not sure if you are asking if what you have written is correct, but the answer is yes.
