Some verbs, usually indicating feelings, states or general facts, simply cannot be used in this tense -- or at least, not usually. "know" and "understand" are two examples.
Quote:
"what do you do at this holiday?"
it refer to repeated action and true in general is it? or it refer to what that particular person do during ONly that holiday..

"What do you do on this holiday?" would mean that "this holiday" happens regularly. For example:
"Every year, I go to Barbados on holiday."
"And what do you do on this holiday?"
"Well, usually...."
If you are talking about one specific holiday in the future or the present:
"Next year, I am going to Marbella instead."
"And what are you doing on this holiday?"
"Well, my plan is...."
or:
"Hello! I didn't expect to see you here."
"I'm on holiday."
"Oh. What are you doing on this holiday?"
"I'm just relaxing, having a good time...."
