Perhaps you should try some spelling variations:
iii gender » ii gender, i gender
wang wang » wang yang, wang liang, wang yan
chong yun » chang yun, chen yun, chong en
wang dan » wang yan, wang ban, wang yidan
iii gene » iii rene, iii genome, i gene
iii rep » ii rep
hong yu » wong yue
chen yu » chen y, chen yulu, cheng lu

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 wang dan ((((iii gene) OR (iii gender))) OR (iii rep)) ((chong yun) OR (hong yu)) chen yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang dan ((((iii gene) OR (iii gender))) or (iii rep)) ((chong yun) or (hong yu)) chen yu ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang dan ((((iii gene) OR (iii gender))) or (iii rep)) ((chong yun) or (hong yu)) chen yu ;*.
