Perhaps you should try some spelling variations:
wang yidan » wang yan
wang ryan » wang yan, wang yang, wang ban
yang john » young john, king john, yang jin
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew
bh best » bs best, nth best
tan bh » tan ah, tan b

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 yidan) OR (wang ryan)) tan bh best yang john ((wong sau) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yidan) or (wang ryan)) tan bh best yang john ((wong sau) OR (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yidan) or (wang ryan)) tan bh best yang john ((wong sau) OR (wong siu)) ;*.
