I have downoaded this and although everything I can find is set to English I am still seeing Chinese characters in the date - see shot, also it is showing 'clock' under widget wtf ? yes I know it's a clock but how to get rid ??
You are using a third-party theme with a custom lock screen that has the date hard-coded in Chinese. What did you expect?
And to hide widget labels, go to Home settings and enable "Remove text from widgets".
