Perhaps you should try some spelling variations:
yuan kai » yuan kang, yuan fei, tan kai
yan wang » yuan wang, yang yang, qian wang
wei gene » i gene, iii gene, wei ben
well can » well than, well a, all can
can wong » can hong, can work, can win
wong siu » wong shiu, kong siu, wong sau
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 kai) OR (yan wang)) liang ((wei gene) OR (e gene)) well can wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kai) or (yan wang)) liang ((wei gene) OR (e gene)) well can wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kai) or (yan wang)) liang ((wei gene) OR (e gene)) well can wong siu ;*.
