Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
li young » live young, kim young, all young
wong siu » wong shiu, kong siu, wong sau
yang li » yang lin, yang di, yang xi
l young » _ young, a young, 3 young
sar » sara, star, saur

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yang li ((li young) OR (l young)) john ((dong sin) OR (((wong siu) OR (kong sar)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang li ((li young) OR (l young)) john ((dong sin) or (((wong siu) or (kong sar)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yang li ((li young) OR (l young)) john ((dong sin) or (((wong siu) or (kong sar)))) ;*.
