I love this distro but I just had to have a deepin Plymouth or startup screen. I copied this one from an old install of deepin. You can download it with instructions from this link. Hope you enjoy it.
Sorry but there is an error in the instructions file. Here is the correct version.
sudo mv deepin-logo /usr/share/plymouth/themes
sudo update-alternatives --install /usr/share/plymouth/themes/default.plymouth default.plymouth /usr/share/plymouth/themes/deepin-logo 500
sudo update-alternatives --config default.plymouth
sudo update-initramfs -u
