Perhaps you should try some spelling variations:
yuan chang » yuan cheng, huang chang, han chang
gene hong » eng hong, gene one
hong than » hong tan, long thanh, hong hai
wong sau » wong siu, wong shiu, kong sar
wong sam » kong sar, von sam, wong max
tan li » tang li, tian li, tan yi
lai » laid

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

• Performing a fuzzy search may retrieve terms with similar spellings: yuan chang ((tan li) or (gan li)) gene hong than ((((wong sau) OR (wong sam))) or (wong lai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yuan chang ((tan li) OR (gan li)) gene hong than ((((wong sau) OR (wong sam))) OR (wong lai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan chang ((tan li) or (gan li)) gene hong than ((((wong sau) OR (wong sam))) or (wong lai)) ;*".
