huang lin » huang bin, huang ting, huang ying
zhang zhi » zhong zhi, wang zhi, zhang wei
hua gene » human gene, a gene, hua ren
wan yan » wang yan, nan yan, wai yan
yan tan » tan tan, yan clan, yan guan
tan hua » tuan hua, wang hua, tan chia

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: wan yan tan hua gene ((shang jin) OR (((huang lin) OR (huang jing)))) zhang zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan tan hua gene ((shang jin) or (((huang lin) OR (huang jing)))) zhang zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan tan hua gene ((shang jin) or (((huang lin) OR (huang jing)))) zhang zhi ;*.
