Perhaps you should try some spelling variations:
yuan kang » yuan chang, chan kang, yuan kai
yuan wang » yan wang, yuan chang, qian wang
than wong » thang long, than one, than done
wong shiu » wong siu, cong shu, song shin
we than » we thank, well than, we think
i gene » _ gene, a gene, i gede
e gene » _ gene, a gene

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: ((yuan kang) OR (yuan wang)) liang ((i gene) OR (e gene)) we than wong shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kang) or (yuan wang)) liang ((i gene) OR (e gene)) we than wong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kang) or (yuan wang)) liang ((i gene) OR (e gene)) we than wong shiu ;*.
