dong yang » dong hoang, wang yang, yang yang
gene tang » gene bank
chong ghi » hong ghi, chong yi
zhong zhi » zhang zhi, hong ghi, zhong tai
hua gene » human gene, a gene, hua ren
tang lim » tang li, jung lim, tang jie

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 ((yong yang) OR (dong yang)) hua gene tang lim ((chong ghi) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) or (dong yang)) hua gene tang lim ((chong ghi) OR (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yang) or (dong yang)) hua gene tang lim ((chong ghi) OR (zhong zhi)) ;*.
