Perhaps you should try some spelling variations:
chang soon » chin soon, chang gordon
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
chang won » chang ann, chang min, chang you
yang dai » yang dali, yang di, bang dai
wong sau » wong sam, wong siu, wong shiu
dai yi » bai yi, tai yi
hong » long

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 yang yang dai yi ((chang soon) OR (chang won)) ((wong sau) OR (hong seo)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang dai yi ((chang soon) OR (chang won)) ((wong sau) or (hong seo)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yang dai yi ((chang soon) OR (chang won)) ((wong sau) or (hong seo)) ;*.
