Perhaps you should try some spelling variations:
case done » case one, have done
done sin » dong sin, done using, done so
gong min » jong min, song min, gong meng
yan yuan » yan guan, fang yuan, nan yan
yang jin » yang jie, yang jun, ying jin
yang yue » wang yue, yang yun, yang jui
sin ce » since ce

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

• Performing a fuzzy search may retrieve terms with similar spellings: some case done sin ce ((((gong min) OR (yan yuan))) OR (yang jin)) ((yang yue) OR (yang di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "some case done sin ce ((((gong min) OR (yan yuan))) OR (yang jin)) ((yang yue) OR (yang di)) ;*".
