Welcome to Android Central! Which phone? Some phones from shady manufacturers do this out of the box. Another possibility is that some app you installed contained some malware that automatically installs these apps.
So you're saying it still downloads the apps in Safe Mode? You may need to do a factory reset, and make sure it doesn't restore any old backups -- set up the phone like it's brand new, and then sync your Google account.
No. It is not downloading apps in safe mode, I'm saying it isn't showing the Chinese apps in safe mode. As those apps get downloaded, my phone slows down and showing Chinese adds on every apps.
