Perhaps you should try some spelling variations:
yang john » young john, king john, yang jun
tuan hua » tan hua, yuan hui
yang jin » yang jie, yang jun, ying jin
wong sau » wong sam, wong siu, wong shiu
wan yan » wang yan, nan yan, wang yang
wai yan » wang yan, wei yang
tuan vu » thanh vu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wan yan) OR (wai yan)) ((tuan vu) or (tuan hua)) irene ((yang john) or (yang jin)) wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (wai yan)) ((tuan vu) OR (tuan hua)) irene ((yang john) OR (yang jin)) wong sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) OR (wai yan)) ((tuan vu) or (tuan hua)) irene ((yang john) or (yang jin)) wong sau ;".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) OR (wai yan)) ((tuan vu) or (tuan hua)) irene ((yang john) or (yang jin)) wong sau ;*.
