The program itself is translated into various languages, but the manual is only in English.
程序本身被翻译成各种语言，但手册只有英文
你好，英文的手册也可以。
Google Translate on "你好，英文的手册也可以" returns "Hello, English manual is also available".
I'm not sure if Google has translated what you said correctly.
If you're looking for the English manual, itis available via F1 in the program. The Opus Manual links at the top right of the forum also go to the same manual on the web.
