Perhaps you should try some spelling variations:
kang minah » sang minh
yang yang » wang yang, wang yan
wong shiu » song shin, wong sau
wang dan » wang yan, wang ban, wang yidan
yang yue » wang yue, yang yun, yang jui
wong siu » kong siu, wong sau, wong siew
lu kang » wu kang

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 dan ((yang yang) OR (yang yue)) lu kang minah ((((wong shiu) OR (wong siu))) OR (cong shu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan ((yang yang) or (yang yue)) lu kang minah ((((wong shiu) OR (wong siu))) or (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan ((yang yang) or (yang yue)) lu kang minah ((((wong shiu) OR (wong siu))) or (cong shu)) ;*.
