Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, dan yang
yang yang » wang yang, wang yan
dong hong » dong hoang, hong hong, kong hong
yong shu » cong shu, tong shui, wong shiu
a brain » _ brain
yan jim » yang jie, yang jin
yan jiu » yang jie, yang jin, pang jiu

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((dong yang) or (yang yang))) or (dong hong)) a brain ((yan jim) OR (yan jiu)) yong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((dong yang) OR (yang yang))) OR (dong hong)) a brain ((yan jim) OR (yan jiu)) yong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((dong yang) or (yang yang))) or (dong hong)) a brain ((yan jim) OR (yan jiu)) yong shu ;*".
