yong ying » yirong ying, ying yang
dong yang » dong hoang, wang yang, yang yang
gene tang » gene bank
chong ghi » hong ghi, chong yi, zhong zhi
fong yin » fong ben, song yun, wong yi
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.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((yong ying) OR (fong yin))) or (dong yang)) hua gene tang lim chong ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yong ying) OR (fong yin))) OR (dong yang)) hua gene tang lim chong ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yong ying) OR (fong yin))) or (dong yang)) hua gene tang lim chong ghi ;*".
