凡是 means any, all, or every case of in a broad, rule-like sense. In this sentence, 凡是……都…… forms a very common pattern:

• 凡是 A，都 B
• Whenever / Any time / Anything that is A, it is B
• All those that meet condition A must/do B

So:

• 凡是需要寄存的行李，都要送到前台。
• Any luggage that needs to be checked/stored must be taken to the front desk.

Compared with other words:

• 所有 = all, all of
• 任何 = any
• 凡是 often sounds more like a general rule or policy.

So this sentence has the feeling of an instruction or hotel rule.

都 is often used with words like 凡是, 所有, 大家, 这些, etc. to mean all.

Here, 凡是……都…… works as a pair:

• 凡是需要寄存的行李，都要送到前台。

This means:

• As for all luggage that needs to be stored, all of it must be taken to the front desk.

Even though English would not always need a separate word like all, Mandarin often uses 都 to mark that the rule applies across the whole category.

Without 都, the sentence would sound less complete and less natural in this pattern.

This is a modifier + 的 + noun structure.

Break it down:

• 需要寄存 = need to be stored / need storage
• 的 = links the description to the noun
• 行李 = luggage

So:

• 需要寄存的行李 = luggage that needs to be stored

This is a very important difference from English. In English, the descriptive clause usually comes after the noun:

• the luggage that needs to be stored

In Mandarin, that descriptive part comes before the noun:

• [needs storing] 的 luggage

This is one of the most common Mandarin sentence patterns.

Here, 的 turns 需要寄存 into a modifier for 行李.

You can think of it like this:

• 需要寄存 = to need to be stored
• 需要寄存的 = that which needs to be stored
• 需要寄存的行李 = luggage that needs to be stored

So 的 is not showing possession here. It is marking a descriptive phrase attached to a noun.

If you remove 的, the phrase becomes ungrammatical:

• 需要寄存行李 = can mean need to store luggage
• but not luggage that needs to be stored

So 的 is necessary here.

No. Here 要 means must, need to, or be required to.

Mandarin 要 can have different meanings depending on context:

• 我要咖啡。 = I want coffee.
• 明天要下雨。 = It is going to rain tomorrow.
• 你要早点来。 = You need to come early.
• 都要送到前台。 = must all be taken to the front desk.

In this sentence, because it is giving a rule or requirement, 要 clearly means must / should / need to, not want to.

到 shows the destination clearly.

• 送 = to deliver / bring / send
• 送到 = to deliver to / bring to a place

So:

• 送到前台 = bring it to the front desk

The 到 makes the endpoint explicit. It is very common with motion or transfer verbs:

• 拿到办公室 = take to the office
• 送到门口 = bring to the door
• 搬到楼上 = move upstairs

In everyday speech, sometimes people may shorten things, but 送到前台 is the standard and clearer form.

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

Typical situations:

• leaving luggage at a hotel front desk
• storing bags at a station
• checking belongings somewhere temporarily

It is not exactly the same as simply put away or store in general. It usually implies:

• someone else keeps it for you
• it is temporary
• there is a service or designated place for it

So in this sentence, 寄存行李 means something like:

• check luggage
• leave luggage for storage
• deposit luggage for safekeeping

Mandarin often leaves this kind of meaning implicit.

需要寄存的行李 literally looks like:

• luggage that needs to store/deposit

But the natural understanding is:

• luggage that needs to be stored
• luggage that needs checking

Mandarin often does not require a passive form where English does. The object can be understood from context.

For example:

• 要洗的衣服 = clothes that need washing / need to be washed
• 要修的车 = the car that needs repairing / needs to be repaired
• 需要寄存的行李 = luggage that needs to be stored

So the passive idea is there in meaning, even without 被.

It can be either, depending on context. 行李 is a collective noun, like luggage in English.

So it can refer to:

• one piece of luggage
• several bags
• luggage in general

In this sentence, the meaning is general, so it is best understood as:

• any luggage
• all luggage that needs to be stored

That is also why 都 fits naturally: the rule applies to all relevant luggage.

The first part sets up the category or condition, and the second part gives the rule.

Structure:

• 凡是需要寄存的行李， = as for any luggage that needs to be stored
• 都要送到前台。 = it must all be taken to the front desk

This kind of topic-first structure is very common in Mandarin. The comma helps separate:

1. the group being talked about
2. what is said about that group

So the sentence flows like:

• Any luggage that needs storage — that kind of luggage must be taken to the front desk.

Yes, but the tone and nuance change a little.

Possible alternatives:

• 所有需要寄存的行李，都要送到前台。

  • All luggage that needs to be stored must be taken to the front desk.
  • Very direct and natural.

• 任何需要寄存的行李，都要送到前台。

  • Any luggage that needs to be stored must be taken to the front desk.
  • Also possible, with a slightly stronger any feeling.

• 凡是需要寄存的行李，都要送到前台。

  • Sounds especially like a general rule or policy statement.

So all three can work, but 凡是……都…… is particularly common in formal notices or instructions.

Mandarin often leaves the subject unstated when it is obvious from context.

Here, the sentence is probably a rule on a sign, notice, or hotel instruction. The implied subject could be:

• guests
• staff
• whoever is handling the luggage

English often wants an explicit subject, but Mandarin does not always need one.

So the real meaning is something like:

• Any luggage that needs to be stored must be taken to the front desk.
• Please take any luggage for storage to the front desk.

The focus is on the rule, not on naming the person responsible.

Usually yes, or at least a reception/front-counter area.

前台 often means:

• front desk
• reception desk
• reception area

It is common in places like:

• hotels
• offices
• clinics
• service centers

In this sentence, because it talks about 寄存行李, a hotel or similar lodging context is especially likely.

So 前台 here is best translated as the front desk.

Yes. It sounds quite natural as a rule, policy statement, or posted instruction.

Reasons it sounds formal/instructional:

• 凡是……都…… gives a rule-like tone
• 需要寄存的行李 is a formal noun phrase
• 要送到前台 expresses a requirement

A more conversational version might be something like:

• 要寄存的行李请送到前台。
• If you need to store your luggage, please bring it to the front desk.

So the original sentence is grammatically normal, but it sounds especially suitable for signage, staff instructions, or written policy.
