Perhaps you should try some spelling variations:
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew
yang li » yang lin, yang di, yang xi
hua ren » hua chen
ren tan » ren yan, chen tan
hong yu » wong yue
yan li » yuan li, gan li, yan zi
tan li » tang li, tian li, gan li
wang » wing, wan, lang

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

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