Micro Express ZTO Express, back door pick up, till one o'clock, expired! Remember the number 175. What is this micro-express?

Micro Express is a software for querying express delivery. I've received messages like this. I asked the courier who sent me a text message why it was not a normal text message, but a micro-express. He said that their couriers need to send a lot of text messages every day, which is quite expensive. The short messages provided by the company's micro-express are much lower than the telecom charges, so they are all sent through the channels of such service providers. The previous micro-express can't be saved, just consider it a low-priced advertisement.

I'm also curious about using micro-express, which is still good. It's convenient to check express delivery, and you can import orders from Taobao JD.COM.

All hands up, hope to adopt.
