Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang john » young john, king john, yang jin
lang yan » wang yan, zhang yan, yang yang
vu irene » _ irene
wong sau » wong sam, wong siu, wong shiu
tuan vu » thanh vu, tuan hua
sar » sara, star, saur

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) OR (wang yang)) tuan vu irene yang john ((((wong sau) or (cong shu))) or (kong sar)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((lang yan) OR (wang yang)) tuan vu irene yang john ((((wong sau) OR (cong shu))) OR (kong sar)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yan) OR (wang yang)) tuan vu irene yang john ((((wong sau) or (cong shu))) or (kong sar)) ;".
• Adding a wildcard symbol may retrieve word variants: ((lang yan) OR (wang yang)) tuan vu irene yang john ((((wong sau) or (cong shu))) or (kong sar)) ;*.
