Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang
hua irene » hua ren
yang hua » wang hua, yang hui, ying hua
yang lin » yang jin, wang lin, yang li
lin wong » lin zong, kie wong, lin ling
wong sau » wong sam, wong siu, wong shiu

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

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