It sucks if you use Chinese thought to answer this kind of Qs. The rule for this in English is always make comment on the truth, not on the sentence of the question. Or simply approve or disapprove on the verb. i.e. "You don't like China?" or "Don't you like China?" If you like China, say YES. If you don't like China, say NO. The Yes or No is about "like", not about the "Don't".

Let's have some fun now:

Q: Now you still don't clear?
A1: No ( still not clear)
A2: Yes ( I'm clear)
