官方更新说明：

Stata 可选择中文本土化用户界面 (Chinese language support has been added).

         Stata's menus, dialogs, and the like can now be displayed in Chinese, as well as Japanese, Spanish, and
         Swedish.  Manuals, help files, and output remain in English.

         If your computer language is set to Chinese (zh), Stata will automatically display the user interface in
         Chinese.  To change languages manually using Stata for Windows or Unix, select Edit > Preferences >
         User-interface language...; to change languages manually using Stata for Mac, select Stata 15 >
         Preferences > User-interface language....  You can also change the language from the command line; see
         [P] set locale_ui.
