Perhaps you should try some spelling variations:
thing lens » thin lens, thing leads, nothing less
yan klang » den klang, yan clan, yan liang
time last » time list, time past, time lost
dong sign » among sign, dong bin
die last » died last, die lasten, die lage
wang » wing, lang
sin » sind, skin, sein

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (wang or wan) yan klang ((die last) or (time last)) thing lens ((dong sign) OR (dong sin)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) yan klang ((die last) OR (time last)) thing lens ((dong sign) OR (dong sin)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan klang ((die last) or (time last)) thing lens ((dong sign) OR (dong sin)) ;*".
