The Windows 10 Enterprise G or Windows 10 Enterprise GN (Chinese Government Edition) is only available in Chinese.
An Enterprise version is always activated via a KMS server.
This activation is normally valid for 180 days. After that the activation is checked again and you have 6 months rest again.
But this new version is knitted differently. If you call up the data via slmgr.vbs, you will see that this new version is activated for 150,000 days or 410.6 years.
Whether this is a mistake, or whether it is wanted / forced cannot be said exactly now.
But with this activation you don't need server access anymore.
