You can get live wallpaper from places like this,
https://moewalls.com/resolution/2560x1440/#google_vignette
Just make sure you download the exact resolution of your screen. The dudu I have is the 11 so 2560x1440 is perfect.
Once you download them, copy them over to the dudu with a usb stick, go to wallpapers and click the little + to add a wallpaper.
