Hộp này giống bưu kiện kia.

Vietnamese often does not use a copula like is/are when the predicate is an adjective or adjective-like word.

Here, giống means similar / resembling, so the structure is simply:

• Hộp này = this box
• giống bưu kiện kia = resembles that parcel

So the whole sentence is literally closer to:

• This box resembles that parcel
• or This box is similar to that parcel

You do not need là here. Using là would sound unnatural in this sentence.

In this sentence, giống means similar to, like, or resembling.

So:

• Hộp này giống bưu kiện kia.
  = This box is like that parcel.

A useful pattern is:

• A giống B = A is similar to B

Examples:

• Con mèo này giống con mèo kia. = This cat looks like that cat.
• Hai cái này giống nhau. = These two are alike / the same.

In Vietnamese, demonstratives such as this and that usually come after the noun, not before it.

So:

• hộp này = this box
• bưu kiện kia = that parcel

This is one of the most important word-order differences from English.

Compare:

• English: this box

• Vietnamese: hộp này

• English: that parcel
• Vietnamese: bưu kiện kia

They are both demonstratives, but they differ in distance:

• này = this, near the speaker
• kia = that, farther away

So in this sentence:

• hộp này = this box
• bưu kiện kia = that parcel

You may also see đó for that in many situations. Very roughly:

• này = this
• đó / kia = that

The exact feel can vary by context and region, but này vs kia is a very standard contrast.

No. In normal Vietnamese, the noun comes first, and the demonstrative follows it.

Correct:

• hộp này
• bưu kiện kia

Incorrect:

• này hộp
• kia bưu kiện

So remember the pattern:

• noun + này
• noun + kia

Here, hộp is a regular noun meaning box.

It is not acting as a classifier in this sentence.

So:

• Hộp này = This box

Vietnamese often allows a bare noun like this, especially when the meaning is clear from context.

You could also hear:

• Cái hộp này

That also means this box, with cái functioning as a classifier. In many everyday situations, both are possible, though the version with a classifier can feel a little fuller or more natural depending on context.

Bưu kiện means parcel, postal package, or package sent by mail/shipping.

It is a bit more specific than just any package. It usually suggests something being shipped or mailed.

So:

• bưu kiện = parcel / mailed package

If you just want to say a general package, Vietnamese might also use words like gói hàng in some contexts.

Vietnamese often uses classifiers, but they are not always required in every sentence.

A learner may expect:

• Cái hộp này giống bưu kiện kia.

That is also possible.

But Vietnamese can often omit the classifier when the noun itself is clear and specific enough in context. So:

• Hộp này giống bưu kiện kia.
  is perfectly understandable and natural.

In other words, Vietnamese noun phrases are often more flexible than a beginner first expects.

No, not necessarily.

In English, we say:

• similar to
• looks like

But in Vietnamese, giống can directly link the two nouns:

• A giống B

So:

• Hộp này giống bưu kiện kia.

You may also encounter forms like:

• giống như
• giống với

But in a simple sentence like this, just giống + noun is very common.

This is a very common learner question, because Vietnamese word classes do not always match English neatly.

In this sentence, giống behaves like a predicate word meaning to resemble / similar. Depending on the grammar explanation you read, it may be described as:

• a verb
• an adjective
• or a stative verb

For practical learning, the most useful thing is the pattern:

• A giống B = A is like B / A resembles B

So even if the label varies, the sentence structure is what matters most.

Usually no. Giống means similar, not identical.

So the sentence suggests:

• the box looks like that parcel
• the box resembles that parcel
• they are alike in appearance, shape, size, etc.

If you want to say they are exactly the same, Vietnamese would use different wording, such as:

• giống hệt
• y hệt
• y như
• or expressions meaning the same

So giống by itself usually means similar, not exactly the same.

It is grammatically fine and easy to understand.

However, depending on what you mean, native speakers might also say things like:

• Hộp này trông giống bưu kiện kia. = This box looks like that parcel.
• Hộp này giống cái bưu kiện kia.
• Cái hộp này giống bưu kiện kia.

Adding trông makes it more explicitly about appearance: looks like.

Without trông, giống is still perfectly good and natural.

A rough English-friendly approximation is:

• Hộp này giống bưu kiện kia
• roughly: hawp nigh zyohng byoo kee-uhn kee-uh

A few notes:

• hộp has a short ending sound, almost cut off
• giống begins with a z/y-like sound in many accents
• bưu is close to byoo
• kiện has a broken/glottal quality because of the tone

This is only a rough guide. Vietnamese tones are very important, so listening to native audio is much better than relying on English spelling.

The pattern is:

• [Noun phrase] + giống + [noun phrase]

In this sentence:

• Hộp này = noun phrase 1
• giống = similar to / resembles
• bưu kiện kia = noun phrase 2

So the full structure is:

• This box + resembles + that parcel

This is a very useful pattern you can reuse:

• Xe này giống xe kia. = This vehicle is like that one.
• Bạn giống anh ấy. = You resemble him.
• Nhà này giống nhà cũ của tôi. = This house is like my old house.
