how do you feel? or how are you feeling?

Could you tell me what the difference between 'how are you feeling?' and 'how do you feel?'.
Actually, the original question requires students to ask a question according to the answer.

We are ( happy ).

Then my answer is 'how are you feeling?'. But the teacher said I'm wrong. Pay attention please! the 'you' here is concrete. Because the question has a solid form as ' __ ___ you ___?'.
Maybe the answer is neither 'how are you feeling' nor 'how do you feel'. So what is your answer?

I don't see any real difference between "How do you feel?" and "How are you feeling?". Does your teacher say there is a difference between the two?

not a teacher

In my opinion, both of the questions (How do you feel?, How are you feeling?) are perfectly appropriate for the answer that is provided (We are happy.). Unless further information is given about the context, I feel that your teacher is wrong to say that one of those questions is more correct than the other.

You start with the answer and then come up with the question?
