Grammar explanation
Time up to a point in the past
We use the past perfect simple (had + past participle) to talk about time up to a certain point in the past.
She'd published her first poem by the time she was eight.
We'd finished all the water before we were halfway up the mountain.
Had the parcel arrived when you called yesterday?
Past perfect for the earlier of two past actions
We can use the past perfect to show the order of two past events. The past perfect shows the earlier action and the past simple shows the later action.
When the police arrived, the thief had escaped.
It doesn't matter in which order we say the two events. The following sentence has the same meaning.
The thief had escaped when the police arrived.
Note that if there's only a single event, we don't use the past perfect, even if it happened a long time ago.
The Romans spoke Latin. (NOT
The Romans had spoken Latin.)
Past perfect after before
We can also use before + past perfect to show that an action was not done or was incomplete when the past simple action happened.
They left before I'd spoken to them.
Sadly, the author died before he'd finished the series.
Adverbs
We often use the adverbs already (= 'before the specified time'), still (= as previously), just (= 'a very short time before the specified time'), ever (= 'at any time before the specified time') or never (= 'at no time before the specified time') with the past perfect.
I called his office but he'd already left.
It still hadn't rained at the beginning of May.
I went to visit her when she'd just moved to Berlin.
It was the most beautiful photo I'd ever seen.
Had you ever visited London when you moved there?
I'd never met anyone from California before I met Jim.

Hello kingsonselvaraj,
The problem with the sentence is that the phrase 'when I visited Vietnam' provides a finished time reference and so it cannot be used with the present perfect. The present perfect refers to an unfinished time, not a finished time. If you are no longer in Vietnam then that time period is complete and is not consistent with the present perfect.

Hello kingsonselvaraj,
The sentence 'My friend got married to the girl who has been working here in this office"(the girl is still working in the same office' is fine, because the present perfect phrase does not provide a time reference for the past simple action, but simply provides more information about the girl.
As an aside, I would say that the sentence is a little odd and the present perfect does not seem to add any information. A more natural way to phrase it would be to use the present simple (permanent work) or continuous (temporary): 'My friend got married to the girl is working/works here in this office"(the girl is still working in the same office.'

Hello Kingston,
That is correct. Well done!
The past tense gives us information about the book. Grammtically speaking, it is a restrictive or defining relative clause and has an adverbial function. It does not provide a time reference for the verb in the main clause.

Hello corflz
Both forms are possible, but the past simple form is probably better in more contexts than the past continuous form.
All the best
