Some experiments are often like the use of English windows and SQL Server, but sometimes need to use the Chinese environment for easy understanding. The Chinese SQL Server cannot be installed on the English Windows system.
The following compatibility is available according to the documentation
Localized versions of all operating systems are supported in the English version of SQL Server.
By using the Windows Multilingual User Interface Pack (MUI) setting, the localized version of SQL Server is supported in the English version of the localized operating system that has the appropriate language or the supported operating system.
Localized versions of SQL Server can only be upgraded to localized versions of the same language and cannot be upgraded to the English version.
Localized versions of SQL Server can also be installed in parallel with the English instance of SQL Server.

Of course you can also use the comparison toss of the next English Windows then installed corresponding to the required language pack, and then install the corresponding SQL Server language environment version required, of course, need to modify some regional languages and so on.
