Sơ đồ tham quan có phòng trưng bày.

A natural word-by-word breakdown is:

• sơ đồ = map, diagram, layout, plan
• tham quan = visiting, sightseeing, touring
• sơ đồ tham quan = a visitor map, tour map, or site plan for visitors
• có = has, contains, includes, there is/are
• phòng trưng bày = exhibition room, gallery, showroom

So the sentence means something like The visitor map includes a gallery or There is a gallery on the visitor map, depending on context.

Because in Vietnamese, modifiers often come after the noun they describe.

So:

• sơ đồ tham quan literally looks like map visiting
• but it actually means map for visiting or visitor map

This is very common in Vietnamese. English often puts the modifier before the noun, but Vietnamese often puts it after.

If you changed the order, the meaning would change or become unnatural.

It comes from a verb meaning to visit or to sightsee, but here it is not acting like the main verb of the sentence.

In sơ đồ tham quan, it functions more like a modifier describing the kind of sơ đồ it is. So you can think of it as:

• a map for visiting
• a map used by visitors
• a visitor map

Vietnamese often uses verb-like words this way inside noun phrases.

có is very flexible. It can mean:

• to have
• there is / there are
• to include / contain

In this sentence, có is expressing that the map includes or shows the existence of a phòng trưng bày.

So depending on how you translate it, có could become:

• has
• includes
• contains
• there is

English chooses one version, but Vietnamese often uses the same word, có, for all of these related ideas.

Vietnamese does not use articles the way English does.

That means:

• sơ đồ tham quan can mean a visitor map or the visitor map
• phòng trưng bày can mean a gallery or the gallery

Context tells you which one is meant.

This is very normal in Vietnamese. You should not expect a separate word matching English a/an/the in every sentence.

Because Vietnamese often leaves out một when simply stating that something exists or is included.

So:

• có phòng trưng bày = there is a gallery / it has a gallery
• có một phòng trưng bày = there is one gallery / there is a gallery

Adding một makes the noun more explicitly singular or indefinite, but it is often unnecessary.

In short, both can work, but the version without một is very normal.

It is a phrase, but it behaves like one vocabulary unit.

• phòng = room
• trưng bày = to display, to exhibit

Together, phòng trưng bày means:

• exhibition room
• gallery
• sometimes showroom, depending on context

So even though it has more than one written word, you should learn it as a set expression.

The pattern is:

[noun phrase] + có + [noun phrase]

In this sentence:

• Sơ đồ tham quan = the subject/topic
• có = has / includes / there is
• phòng trưng bày = the thing being mentioned

So the structure is very straightforward: The visitor map + has/includes + a gallery

This is a very common Vietnamese pattern.

Not directly.

Vietnamese does not change verbs for tense the way English does. The sentence has no special verb ending or tense marker. By default, this kind of sentence is usually understood as present or general from context.

So có here is naturally understood as something like:

• has
• includes
• there is

If you wanted to make the time clearer, Vietnamese would usually add time words rather than change the verb itself.

It is understandable, but a native speaker might sometimes make the relationship clearer with an extra word such as trong or trên.

For example:

• Trong sơ đồ tham quan có phòng trưng bày = There is a gallery in/on the visitor map
• Trên sơ đồ tham quan có phòng trưng bày = There is a gallery on the visitor map

The original sentence is short and possible, but it can feel a little compact. Vietnamese often adds those location words to make the meaning more explicit.

Yes. Because sơ đồ is a broad word, possible translations include:

• visitor map
• tour map
• site plan
• layout for visitors
• tour layout

The best choice depends on context. If this is a map in a museum or tourist site, visitor map or site map may sound most natural in English.
