Perhaps you should try some spelling variations:
wang wang » wang liang, wang yan, wang yong
wang yang » wang yan, wang liang, wang yanling
yang john » young john, king john, yang jin
yuhan vu » tuan vu
vu irene » _ irene
wong sau » wong sam, wong siu, wong shiu
jing ji » ying jin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang wang) OR (wang yang)) yuhan vu irene ((yang john) or (jing ji)) wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang yang)) yuhan vu irene ((yang john) OR (jing ji)) wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) OR (wang yang)) yuhan vu irene ((yang john) or (jing ji)) wong sau ;*".
