gene tang » gene bank
chong ghi » chong yi
zhong zhi » zhang zhi, zhong tai
yang hua » wang hua, yang hui, ying hua
hua gene » human gene, a gene, hua ren
tang lim » tang li, jung lim, tang jie
hong ghi » hong g, hong hai
wang » wing, wan, lang

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