yang hua » wang hua, yang hui, ying hua
hua gene » human gene, a gene, hua ren
min hong » amin hong, tin hong, min hyoung
hong ghi » zhong zhi, hong g, hong hai

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) OR (wang yang)) yang hua gene chang min hong ghi ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yong) or (wang yang)) yang hua gene chang min hong ghi ;*.
