They're all the same format...

[DHL/FedEx/the Chinese consulate] has an urgent package for you to pick up.

[Failure to pick up the package will result in the package being returned to the original sender./The package has been confiscated in customs due to irregularities. Failure to contact us will result in a formal investigation.]

Please call us... etc.

There are other formats. Here's one that my wife (who is originally from China) got:

This guy calls claiming to be from the Beijing police. They claim that after she left China, someone stole her identity and tried to make some transactions in her name. They managed to stop him, but now they're investigating and they need to gather evidence. And so they need to get her id and bank account details, etc.

For a while they completely had both of us, and we believed everything they said up until they were asking for her details. She asked for a name and id number, and said she'd call them back. When she looked up the real Beijing police phone number and called them, they said they had no idea what she was talking about.

Ah right; I can't believe I forgot about that! I was just talking with someone who got strung along like that as well. Luckily she bailed out as well.

Today I learned they've morphed.

I assumed they want money in order to complete the delivery, but searching online it appears they want to verify someone will be home and nothing comes of it.

Seem to be some thought they're verifying names and addresses. Weird.

One day almost all the phones started ringing in the office one by one. Turns out someone/some automated system started dialing our phone numbers one by one with the above Chinese message scam. At that time I realized I never needed my office phone before and unplugged it. Problem solved.
