Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
hua brain » human brain, a brain, hua ban
brain yan » brain gain, brain a
done sin » dong sin, done using, done so
wong sam » wong sau, kong sar, von sam
kong siu » kong eiu, wong siu, dong sin
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: ((done sin) or (yang yang)) ya hua brain yan jiu ((((wong sam) OR (wong lai))) or (kong siu)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((done sin) OR (yang yang)) ya hua brain yan jiu ((((wong sam) OR (wong lai))) OR (kong siu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((done sin) or (yang yang)) ya hua brain yan jiu ((((wong sam) OR (wong lai))) or (kong siu)) ;*".
