Perhaps you should try some spelling variations:
yuan wang » yuan kang, yuan chang, qian wang
than wong » thang long, than one, than done
yan wang » yang yang, qian wang, yan liang
iii gene » iii rene, iii gender, iii genome
one than » money than, more than, one thing
wong sau » wong sam, wong siu, wong shiu
li gene » i gene, l1 gene, lof 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 wang) OR (yan wang)) liang ((li gene) OR (iii gene)) one than wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan wang) or (yan wang)) liang ((li gene) OR (iii gene)) one than wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan wang) or (yan wang)) liang ((li gene) OR (iii gene)) one than wong sau ;*.
