Why in gods name are you using Kingsoft Writer? Don't you have MS Word?
This is for the 2013 version!
Step 1 Open an existing document with Kingsoft Writer
Step 2 Under Classic interface, go to Tools > Set Language.
Under 2013 interface, go to Review > Check Spelling > Set Language.
Step 3 In the Set Language dialog, choose a default language for spell check and press Set as default.
The default dictionary is successfully changed to English (United Kingdom). You will find that Writer automatically checks spelling according to your new choice of language.
If you need to switch back to English (United States) dictionary, simply repeat the above steps again. See this video:0
