What kind of mobile phone is the demo machine sold in Ji Liang street?

Let's talk about what a demo machine is:

The so-called demonstration is a sample for customers to see, that is, a machine that you put on the desktop for people to play when you go to Apple's physical store, and a machine that Apple gives to an authorized store for free as a display!

The display machine is not allowed to be sold to the public, but is only used to show the operation of the mobile phone to customers. There is no difference between hardware and real machines. You can also call and send text messages, but the software is different, which limits the use of some functions. "The system of the display machine has been modified, which limits the fingerprint identification, recovery function, download and installation, etc. However, it can be brushed normally, and there is no difference between brushing and selling through normal channels. The only difference is that you go to Settings-General-about this machine and look at the model, which starts with the number 3. Normally, it should start with M or N..

So it's cheaper to buy this price, even a little cheaper than the official exchange machine. Don't worry about upgrading the function in the future. If you want to buy it, just pay attention to whether it has been dismantled and repaired and whether the price is reasonable.
