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