Chúng ta thà ngắm sao còn hơn trực đêm.

Chúng ta means we, including the person being spoken to.

• chúng ta = we/us, including you
• chúng tôi = we/us, not including you

So Chúng ta thà... means the speaker is including the listener: We’d rather...

This is a very common Vietnamese pattern for expressing preference between two options.

thà A còn hơn B = would rather A than B

In this sentence:

• thà ngắm sao = would rather watch the stars / go stargazing
• còn hơn trực đêm = than do a night shift / than stay on night duty

So the structure is:

• thà
  • preferred option
• còn hơn
  • less preferred option

It is similar to English would rather ... than ...

Vietnamese often does not translate English helper words one-for-one.

In English, would rather uses would as part of the expression. In Vietnamese, the idea of preference is already contained in the pattern thà ... còn hơn ..., so no separate word for would is needed.

This is very common in Vietnamese:

• grammar meaning is often carried by a whole pattern
• not every English function word has a direct equivalent

Here, còn hơn helps form the comparison of preference: rather ... than ...

• hơn by itself often means more than or marks comparison
• còn hơn in this pattern strengthens the contrast between the two choices

So in thà A còn hơn B, còn hơn is best understood as part of a set expression, not as something you should translate word-by-word.

You may also hear related patterns such as:

• thà A hơn B
• thà A chứ không B

But thà ... còn hơn ... is very natural and clear.

Because Vietnamese verbs do not use an infinitive marker like English to.

So:

• ngắm sao = watch stars / stargaze
• trực đêm = do night duty / work the night shift / be on night watch

Vietnamese often places a verb directly before its object or complement:

• ăn cơm = eat rice / have a meal
• xem phim = watch a movie
• trực đêm = be on night duty

There is no equivalent of English to in forms like to watch or to work.

ngắm means to look at something attentively, to admire, or to gaze at.

So ngắm sao means:

• to gaze at the stars
• to watch the stars
• to go stargazing

It sounds more deliberate and appreciative than just nhìn sao.

A rough comparison:

• nhìn = look
• xem = watch
• ngắm = gaze at / admire

trực đêm means being on duty at night.

Depending on context, it can mean:

• doing a night shift
• standing night watch
• being on call overnight
• staying on duty through the night

trực is often used in work or duty contexts, such as hospitals, security, military settings, reception, emergency services, and similar situations.

So trực đêm is not just staying awake at night. It usually implies a responsibility or assigned duty.

In this sentence, sao means star(s) because of the phrase ngắm sao.

It is true that sao can also mean why/how come in other contexts, for example:

• Sao bạn đến muộn vậy? = Why are you late?

But Vietnamese relies heavily on context. In ngắm sao, the meaning is clearly gaze at stars, not gaze at why.

So this is a good example of how one written form can have different meanings depending on context.

Vietnamese nouns usually do not have to show singular/plural the way English does.

So sao can mean:

• star
• stars

The context tells you what sounds natural. With ngắm sao, English usually translates it as watch the stars or go stargazing, even though Vietnamese does not add an -s-type ending.

This is very normal in Vietnamese:

• mua sách = buy book/books
• nuôi mèo = raise a cat / raise cats
• ngắm sao = gaze at the stars

Yes, in the right context, Vietnamese often drops subjects if they are already understood.

So someone might say simply:

• Thà ngắm sao còn hơn trực đêm.

This still makes sense as Better to stargaze than do the night shift or I’d/We’d rather stargaze than do night duty, depending on context.

However, keeping chúng ta makes it explicit that the speaker is saying we, including the listener.

A few words here may be tricky for English speakers:

• thà: low falling tone
• ngắm: watch the ng at the beginning and the glottalized dipping-rising tone pattern
• trực: the tr sound and final -c stop may be difficult
• đêm: starts with đ, which is like an English d, not the plain Vietnamese d

A few pronunciation tips:

• ng can start a syllable in Vietnamese, unlike in English. Practice it slowly: ngắm
• final -c is unreleased, so trực ends abruptly
• đ is a separate consonant from d
• tones matter, especially for short words like thà, sao, and đêm

If you learn the sentence as chunks, it becomes easier:

• chúng ta
• thà ngắm sao
• còn hơn trực đêm

It sounds natural and understandable. The structure thà ... còn hơn ... is standard and common.

That said, the exact naturalness depends on context:

• ngắm sao is a bit more expressive than plain everyday speech
• trực đêm sounds practical and work-related

So the sentence has a slightly colorful contrast: something pleasant and romantic-like (stargazing) versus something tiring and duty-based (night duty). That makes it sound vivid, but still perfectly normal Vietnamese.
