Perhaps you should try some spelling variations:
yuan kang » yuan wang, yuan chang, chan kang
qian yan » qian jun, qian yi
ling iii » klang iii, ling li
iii gene » iii rene, iii gender, iii genome
done sau » done so, done a, wong sau
gene we » gene w, gene one, gene set
we than » we thank, well than, we think
done hu » done how, done why, dong hua

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 (qian yan)) ling iii gene we than ((done sau) OR (done hu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kang) or (qian yan)) ling iii gene we than ((done sau) OR (done hu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kang) or (qian yan)) ling iii gene we than ((done sau) OR (done hu)) ;*.
