Tôi làm xong việc ở văn phòng rồi và sắp đi đón An.

Xong shows that the action is completed.
So làm xong means finish doing or do something to completion.

• làm việc = work
• làm xong việc = finish the work / finish what needs to be done

Without xong, Tôi làm việc ở văn phòng would usually just mean I work in the office or I am working in the office, not necessarily that the work is finished.

Here, rồi marks that the first action is already completed and often adds a sense of now that that part is done.

So:

• Tôi làm xong việc ở văn phòng rồi = I’ve finished my work at the office already / I’m done with the office work now

In everyday Vietnamese, rồi is very common for completed situations, especially when the result matters in the present.

Because rồi already makes the completion clear, and in natural speech Vietnamese often leaves out đã when the meaning is obvious.

Possible versions:

• Tôi làm xong việc ở văn phòng rồi = natural, common
• Tôi đã làm xong việc ở văn phòng rồi = also correct, slightly more explicit

So đã is not wrong; it is just not necessary here.

Sắp means about to or soon going to. It suggests the action will happen very shortly.

• sắp đi đón An = about to go pick up An

Sẽ just means will, with a more general future meaning.

Compare:

• Tôi sắp đi đón An = I’m about to go pick up An
• Tôi sẽ đi đón An = I will pick up An

So sắp feels more immediate than sẽ.

Đi đón literally means go pick up. The word đi adds the idea of going somewhere in order to pick An up.

• đón An = pick up An
• đi đón An = go pick up An

In this sentence, sắp đi đón An sounds very natural because the speaker is saying what they are about to go out and do next.

Yes, ở văn phòng means at the office or in the office.

In this sentence, it most naturally tells you where the work was done or where that work belongs contextually. A learner may notice a slight ambiguity:

• làm xong việc ở văn phòng can be understood as finished the work at the office
• depending on context, it could also feel close to finished the office work

Usually context clears this up. In normal conversation, this wording is fine.

If someone wanted to be extra clear, they might say:

• Tôi làm xong việc ở văn phòng rồi = I’ve finished the work at the office already
• Tôi làm xong việc văn phòng rồi = I’ve finished the office work already

Và means and and simply links the two ideas:

1. I’ve finished my work at the office already.
2. I’m about to go pick up An.

Yes, it can sometimes be omitted in speech if the pause and context make the connection clear. But using và is perfectly natural and makes the structure very clear, especially for learners.

Because An is a proper name. Vietnamese does not use articles like the or a before names.

So:

• đón An = pick up An

That is completely normal. Sometimes a title or relationship word can be added depending on context:

• đón bé An = pick up little An / child An
• đón anh An = pick up Mr./older-brother An

But with just the name, An alone is fine.

Not really in the most natural reading. Because of làm xong việc and rồi, the sentence strongly points to finishing a piece of work, not simply stating your job location.

If you wanted to say I work at an office, you would normally say:

• Tôi làm việc ở văn phòng = I work in an office / at the office

Adding xong and rồi changes the meaning to a completed action:

• Tôi làm xong việc ở văn phòng rồi = I’ve finished the work at the office already

Sometimes yes, if the subject is obvious from context. Vietnamese often drops pronouns when they are understood.

For example, in conversation, someone might simply say:

• Làm xong việc ở văn phòng rồi, sắp đi đón An.

That sounds natural if everyone already knows who is speaking. But including Tôi is clearer and is especially helpful for learners.
