I always heard people using these tenses like 'have had' and 'had been'.
As far as I know, the tense 'have been' is used when you did something in the past and still doing it right until now. For instance, I have been eating rice all the while. How do you actually use this tense 'had been', preferably with examples.
I have no idea how do use 'have had' either. Please aid me. Thank in advance.
