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
wong sam » wong sau, wong lai, kong sar
a brain » _ brain
ji wong » ji won, ji zhong, kie wong
yan ji » yan jiu, ban ji, pan ji

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

• 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 ji wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: ((((done sin) OR (done so))) OR (yang yang)) ya ((hua brain) OR (a brain)) yan ji wong sam ;*.
