Perhaps you should try some spelling variations:
long time » long live
time past » time part, time pad, some past
thin zeng » thin end
thin lens » thin line, thin end
dong sign » among sign, dong bin
yan long » yan cong, van long, pain long
wang » wing, wan, lang
sin » sind, skin, sein

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan long time past ((thin zeng) OR (thin lens)) ((dong sign) OR (dong sin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan long time past ((thin zeng) OR (thin lens)) ((dong sign) or (dong sin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan long time past ((thin zeng) OR (thin lens)) ((dong sign) or (dong sin)) ;*.
