Dập lửa rồi thu dọn khu cắm trại.

Vietnamese often leaves out the subject when it is obvious from context, especially in:

• commands
• instructions
• signs
• checklists

So this sentence is understood as an imperative, with an implied you:

• (Bạn) dập lửa rồi thu dọn khu cắm trại.

In natural Vietnamese, leaving out bạn makes it sound more like a straightforward instruction.

Here, rồi means something like then / after that / and then. It connects two actions in sequence:

• Dập lửa → extinguish the fire
• rồi → then
• thu dọn khu cắm trại → clean up / pack up the campsite

So in this sentence, rồi is not mainly marking past tense. It is showing the order of actions.

Vietnamese does use rồi in other ways, including to indicate completion, but in this sentence its most important job is sequencing:

• Put out the fire, then clean up the campsite.

Dập lửa is a very natural way to say put out a fire / extinguish flames, especially when talking about an actual fire that needs to be actively put out.

• dập lửa = extinguish a fire, beat down flames, put out a blaze

By contrast, tắt is often used for things that go off or are turned off, such as:

• tắt đèn = turn off the light
• tắt máy = turn off the engine

You may hear lửa tắt meaning the fire goes out / is out, but for the action of actively extinguishing a campfire, dập lửa sounds more suitable.

Yes. Dập tắt lửa is also correct and common.

Comparison:

• dập lửa = shorter, very natural
• dập tắt lửa = a bit fuller, explicitly extinguish the fire

Both work. In instructions, dập lửa is concise and natural.

Thu dọn means gather up, put away, tidy up, clean up, pack up. It often suggests collecting things and restoring order.

• thu = gather, collect
• dọn = tidy, clear away

Together, thu dọn feels a little more complete than just dọn. For a campsite, thu dọn is a good choice because it can include:

• picking up trash
• packing gear
• clearing the area
• leaving the place neat

So thu dọn khu cắm trại is very natural for clean up / pack up the campsite.

Literally:

• khu = area, zone, section
• cắm trại = camp / camping

So khu cắm trại is literally the camping area or camping site.

Depending on context, it can be translated as:

• campsite
• camping area
• campground area

In this sentence, campsite is a natural translation.

Vietnamese generally follows a straightforward verb-object order:

• dập lửa = extinguish fire
• thu dọn khu cắm trại = clean up campsite

So the structure is basically:

• Verb + object + rồi + verb + object

This is very normal in Vietnamese. English often needs more function words, but Vietnamese can be quite compact.

It can be omitted, but the sentence would feel slightly different.

With rồi:

• Dập lửa rồi thu dọn khu cắm trại.
• clear sequence: first do A, then do B

Without rồi:

• Dập lửa, thu dọn khu cắm trại.
• still understandable, but more like a list of instructions

So rồi is not absolutely required, but it helps emphasize the order of actions.

You could say:

• Hãy dập lửa rồi thu dọn khu cắm trại.

This is grammatical, and hãy makes it explicitly imperative, like please / do in a formal instruction style.

However, Vietnamese often drops hãy in everyday instructions, especially on signs, reminders, or checklists. So the shorter version:

• Dập lửa rồi thu dọn khu cắm trại. is very natural.

Vietnamese does not use articles the way English does. There is no direct equivalent that must appear before nouns in a sentence like this.

So:

• lửa can mean fire / the fire
• khu cắm trại can mean the campsite / a campsite / the camping area

Context tells you which English article sounds best in translation. In an instruction like this, English naturally uses the:

• Put out the fire, then clean up the campsite.

It is fairly neutral and practical. It sounds like:

• an instruction
• a safety reminder
• a checklist item
• a posted rule

It is not especially formal, but it is also not slangy or casual conversation. It has the concise style often used for directions and warnings.

A rough pronunciation guide is:

• Dập ≈ zup or yup in northern speech, but with a short, clipped vowel and a final p
• lửa ≈ lửa with a falling-rising tone on lử
• rồi ≈ zoy or yoy in northern speech
• thu dọn ≈ too yon / too yonn depending on accent
• khu cắm trại ≈ khoo kawm chai

A few useful notes:

• d, gi, r are pronounced differently in different regions.
• In northern Vietnamese, dập and rồi often begin with a z/y-like sound.
• In southern Vietnamese, those initials sound different again.

If you are learning standard northern pronunciation, focus especially on the tones and the final consonants in words like dập.

Yes. Thu dọn can cover both ideas, depending on context.

At a campsite, it may mean:

• clean up the area
• gather your belongings
• pack things away
• leave the site in good order

So in English, both can be appropriate:

• Put out the fire, then clean up the campsite.
• Put out the fire, then pack up the campsite.

If the focus is on environmental responsibility, clean up is often the best translation. If the focus is on preparing to leave, pack up may fit better.
