Perhaps you should try some spelling variations:
yang time » long time, yang jie, lang tim
last thin » last thing, last things
thin zeng » thin end, thin lens
dong sign » among sign, dong bin
lag time » long time, big time
nan yan » nan ya, wang yan, qian yan
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: nan yan ((yang time) OR (lag time)) last thin zeng ((dong sign) or (dong sin)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nan yan ((yang time) OR (lag time)) last thin zeng ((dong sign) OR (dong sin)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan yan ((yang time) OR (lag time)) last thin zeng ((dong sign) or (dong sin)) ;*".
