Perhaps you should try some spelling variations:
tuan hua » tan hua, tuan vu, yuan hui
thanh vu » thanh van, thanh _
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
wong sau » wong sam, wong siu, wong shiu
wan yan » wang yan, wai yan, wang yang
nan yan » nan ya, wang yan, qian yan

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