wùyè zhídào shōudào bàoxiū, cái gàosu wǒ shàngmén shíjiān.

It means not until ... did ... or only after ... then ....

So:

• 直到收到报修，才告诉我上门时间
• = They didn’t tell me the visit time until they received the repair request.

This pattern emphasizes that the second action happened late, only at that point, or not before then.

A simple formula is:

• A 直到 B，才 C
• = A did C only after B
• = A did not C until B

Here:

• B = 收到报修 = receiving the repair request
• C = 告诉我上门时间 = telling me the time of the home visit

才 is very important here because it marks the idea of only then, not until then, or later than expected.

Compare:

• 物业直到收到报修，才告诉我上门时间。
  = They didn’t tell me until after receiving the repair request.

If you remove 才:

• 物业直到收到报修，告诉我上门时间。

This sounds unnatural or incomplete in standard Mandarin, because 直到 often pairs with 才 when you want the meaning not until.

So in this sentence, 才 is not just optional decoration. It helps create the full delayed-action meaning.

物业 here is short for 物业管理 or 物业公司, meaning the property management, building management, or management office.

In everyday Chinese, people often shorten it to just 物业 when talking about:

• apartment complex management
• building maintenance staff
• housing compound administration

So 物业 is not just the abstract idea of property here. It refers to the people or office responsible for managing the building/community.

报修 means to report something for repair or a repair request.

It can behave like either:

• a verb:
  我去报修。 = I’m going to report a repair issue.
• a noun-like word:
  收到报修 = receive a repair request / receive a repair report

In your sentence, it is best understood as a noun-like object of 收到:

• 收到报修 = received the repair request

This is very common in Chinese: many action words can also act like compact event nouns.

收到 emphasizes successful receipt — that something actually arrived or was received.

Compare:

• 收 = to receive / to accept / to collect
• 收到 = to have received, to receive successfully

So:

• 收到报修 = the repair request was actually received
• 收报修 sounds less natural here

In everyday Mandarin, 收到 is very common when talking about getting:

• messages
• emails
• applications
• complaints
• repair requests

So 收到报修 feels natural because it highlights the completed event: the management office actually got the request.

In Mandarin, 告诉 often takes:

• the person being told
• then the information being told

So the pattern is:

• 告诉 + person + information

Here:

• 告诉我 = tell me
• 上门时间 = the visit time / the time they will come over

So:

• 告诉我上门时间
• = tell me the time of the home visit

This word order is very normal in Chinese.

Similar examples:

• 告诉我地址 = tell me the address
• 告诉我原因 = tell me the reason
• 告诉我结果 = tell me the result

Literally:

• 上门 = to come to someone’s door / come on-site / make a home visit
• 时间 = time

So 上门时间 means:

• the time they will come to your place
• the appointment time for the technician/staff to visit
• the on-site visit time

In service contexts, 上门 is very common for:

• repairs
• deliveries
• cleaning services
• installation services

So 上门时间 is a natural service-related phrase.

Because Chinese often forms compact noun phrases by directly putting one noun or verb-like modifier before another noun.

So:

• 上门时间 = the time for coming over
• literally something like door-visit time

You could think of it as a fixed compound-style phrase.

Chinese often omits 的 in short, tight expressions, especially when the relationship is very close or common.

Examples:

• 上课时间 = class time
• 出发时间 = departure time
• 开会时间 = meeting time

If you said 上门的时间, that is also understandable, but 上门时间 is more compact and more natural in service/administrative language.

Yes. That is one of the key meanings of 直到……才…….

The sentence strongly implies:

• before receiving the repair request, they did not tell me the visit time
• only after receiving it did they finally tell me

So there is a built-in sense of delay or late action.

That’s why 才 is important: it often carries the feeling of only then, not before, and sometimes later than expected.

Yes, but the nuance changes.

For example:

• 物业收到报修以后，告诉我上门时间。
• 物业收到报修之后，告诉我上门时间。

These mean:

• After receiving the repair request, the property management told me the visit time.

This is grammatically fine, but it is more neutral. It does not emphasize the not until then idea as strongly.

By contrast:

• 物业直到收到报修，才告诉我上门时间。

specifically highlights that they waited until that point.

So:

• 以后 / 之后 = simple sequence
• 直到……才…… = delayed action / not until

Sometimes, but not always with exactly the same feel.

Possible alternatives:

• 物业到收到报修才告诉我上门时间。
  This is not natural.
• 物业等到收到报修才告诉我上门时间。
  This is possible and natural.
• 物业直到收到报修，才告诉我上门时间。
  This is the most standard for not until.

Differences:

• 直到 = until; often used in more formal or standard statements
• 等到 = wait until; can sound a bit more vivid or conversational

So 等到……才…… can sometimes replace 直到……才……, but 直到 is especially common in this exact structure.

The comma separates the time/background clause from the main action.

Structure:

• 物业直到收到报修，才告诉我上门时间。

The part before the comma:

• 直到收到报修
• sets the condition/time point

The part after the comma:

• 才告诉我上门时间
• gives the main result/action

In short sentences, the comma is sometimes omitted in informal writing, but keeping it makes the structure clearer and easier to read.

It is fairly neutral, with a slightly administrative/service-context feel because of words like:

• 物业
• 报修
• 上门时间

It sounds very natural in contexts like:

• apartment buildings
• maintenance requests
• customer service
• repair scheduling

It is not overly formal, but it is less casual than something like:

• 他们收到报修以后才跟我说什么时候来。

That version is more conversational.

Yes.

For example:

• 物业直到收到报修，才跟我说上门时间。

This is understandable and natural in speech.

Difference in tone:

• 告诉我 = tell me; slightly more standard/direct
• 跟我说 = say to me / tell me; a bit more conversational

In service or written contexts, 告诉我 often sounds a little cleaner. In daily speech, 跟我说 is very common.

A helpful breakdown is:

• 物业 = subject
• 直到收到报修 = time/condition phrase
• 才 = marks delayed or only-then action
• 告诉我上门时间 = main verb phrase

So the structure is:

• Subject + 直到 + event/time + 才 + verb phrase

Applied here:

• 物业
• 直到收到报修
• 才告诉我上门时间

This is a very useful pattern to learn because it appears often in Mandarin:

• 我直到昨天才知道。
  = I didn’t know until yesterday.
• 他直到下班才回我消息。
  = He didn’t reply to me until he got off work.
• 我们直到老师来了才开始。
  = We didn’t start until the teacher arrived.
