kěyǐ zài qiántái jìcún xíngli.

In Mandarin, the subject is often omitted when it is obvious from context.

Here, 可以在前台寄存行李 is a very natural sentence in places like hotels, signs, or service conversations. The implied subject is usually:

• 你 if someone is speaking directly to a guest
• 我们 if a staff member means we can store your luggage for you
• or a general one/you in an informational sense

So Mandarin often leaves this unstated when English would normally include it.

可以 can express several related ideas:

• can
• may
• be allowed to
• it is possible to

In this sentence, it most naturally means something like:

• You can store your luggage at the front desk
• It is possible to store luggage at the front desk
• Luggage may be left at the front desk

So 可以 is not only about physical ability. It often expresses permission or possibility.

Both 可以 and 能 can sometimes be translated as can, but they are not always the same.

• 可以 often focuses on permission or possibility
• 能 often focuses on ability or whether conditions allow something

In this sentence, 可以 is better because the meaning is about service availability or permission:

• 可以在前台寄存行李 = luggage storage at the front desk is allowed/available

If you used 能, it might sound more like asking whether it is physically possible or whether the circumstances permit it, but 可以 is more natural for a service statement.

在 here means at/in and introduces the location where the action happens.

So:

• 在前台 = at the front desk
• 在前台寄存行李 = store luggage at the front desk

A very common Mandarin pattern is:

• 在 + place + verb

Examples:

• 在学校学习 = study at school
• 在家吃饭 = eat at home
• 在前台寄存行李 = store luggage at the front desk

Mandarin usually puts time, place, and other background information before the main verb.

So the structure is:

• 可以 + 在前台 + 寄存 + 行李

This is very typical Mandarin word order. English often puts the place later:

• store luggage at the front desk

But in Mandarin, at the front desk commonly comes before the verb:

• 在前台寄存行李

前台 literally means front desk or reception desk.

It is commonly used in places like:

• hotels
• office buildings
• some service businesses

In this sentence, it most likely refers to a hotel reception/front desk where guests can leave luggage.

寄存 means to leave something in someone else's care for temporary storage.

It is more specific than 放.

• 放 = put/place
• 寄存 = check/store something temporarily with a service desk, locker, or facility

So 寄存行李 is specifically to store/check luggage, not just to put luggage somewhere.

This word is especially common for:

• luggage storage
• left-luggage services
• temporary safekeeping

In Mandarin, nouns usually do not change form for singular or plural.

So 行李 can mean:

• luggage
• a piece of luggage
• bags/luggage in general

The exact number is understood from context. Mandarin does not add an -s ending the way English does.

Also, in English, luggage itself is normally uncountable, so 行李 matches that idea quite well.

Mandarin often leaves out articles and possessives when they are understood from context.

So:

• 寄存行李 = store luggage
• 寄存你的行李 = store your luggage

If the situation already makes it obvious whose luggage is being discussed, 你的 is unnecessary.

Similarly, Mandarin has no direct equivalent of English a/an/the used in the same way. Context usually does that job.

Yes, absolutely.

It is a natural complete sentence in Mandarin, especially in practical contexts such as:

• hotel information
• customer service
• signs
• spoken instructions

Mandarin often allows short, efficient sentences when the context is clear. Even without an explicit subject, this sentence sounds complete and natural.

Yes. That is also correct, and it is very natural.

Compare:

• 可以在前台寄存行李
• 可以把行李寄存在前台

The second sentence uses the 把 construction, which highlights the object 行李 more directly.

Structure:

• 把 + object + verb/result/location

So:

• 把行李寄存在前台 = store the luggage at the front desk

Both are correct. The original sentence is simpler and very common in service language.

A helpful breakdown is:

• 可以 = can / may / it is possible to
• 在前台 = at the front desk
• 寄存 = store/check temporarily
• 行李 = luggage

So the pattern is:

• modal verb + location + main verb + object

That gives:

• 可以 + 在前台 + 寄存 + 行李

This is a very common Mandarin structure and a good pattern to remember.
