daun yang » dan yang, du yang, tan yang
gene sang » lee sang, gene bank
yan yang » yao yang, dan yang, tan yang
hua gene » human gene, a gene, hua ren
sang min » sang minh, song min, tang min
min hong » amin hong, tin hong, min hyoung

You may be able to get more results by adjusting your search query.
