Perhaps you should try some spelling variations:
brain sang » brain using
yang yang » wang yang, wang yan
hua brain » human brain, a brain, hua ban
sang minh » kang minah, anh minh, song min
wong sau » wong sam, wong siu, wong shiu
yan yan » yan yuan, nan yan, wang yan
hong » long

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang ((yan yan) or (yang yang)) hua brain sang minh ((((wong sau) OR (kong sar))) or (hong seo)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((yan yan) OR (yang yang)) hua brain sang minh ((((wong sau) OR (kong sar))) OR (hong seo)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((yan yan) or (yang yang)) hua brain sang minh ((((wong sau) OR (kong sar))) or (hong seo)) ;*".
