How to download/delete band displays on the Xiaomi Smart Band 8?

When the band is connected to the phone, you can download new band displays through the Mi Fitness APP.
Go to the Mi Fitness APP >> [Device] >> [Manage band displays]. You can use it after downloading and importing.
The way of how to delete a band display:
Enter the band interface >> [Settings] >> [Band displays] >> swipe up and down the page to select the band display to be deleted >> tap [Delete] at the upper of the interface.
Go to the Mi Fitness APP >> [Device] >> [Manage band displays] >> [My band displays] >> tap on the corresponding band display >> tap on [Delete].
Note: 
The default band display does not support deletion (factory restore requires restoring the preset band display, so it cannot be deleted here).
