Perhaps you should try some spelling variations:
yuan wang » yan wang, yuan kang, yuan chang
long han » long chain, long thanh, jeong han
yan yuan » yan guan, fang yuan, nan yan
wong siu » wong shiu, kong siu, wong siew
wong sau » wong sam, wong shiu, wong lai
dong di » dong sin
wang au » wang chau, wang hua, wang yan

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: ((((long han) OR (long haul))) OR (dong di)) yan yuan wang au yong ((wong siu) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((long han) or (long haul))) or (dong di)) yan yuan wang au yong ((wong siu) OR (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((((long han) or (long haul))) or (dong di)) yan yuan wang au yong ((wong siu) OR (wong sau)) ;*.
