yan yang » yang yang, yao yang, dan yang
yang hua » wang hua, yang hui, ying hua
hua gene » human gene, a gene, hua ren
ying tan » wing tan, liang tan, ying bank
ying jin » jing ji, yang jie
yang jin » yang jie, yang jun, shang jin
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 yan yang hua gene ((ying tan) OR (((ying jin) OR (yang jin)))) kong (sar OR star) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yang hua gene ((ying tan) or (((ying jin) OR (yang jin)))) kong (sar or star) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yang hua gene ((ying tan) or (((ying jin) OR (yang jin)))) kong (sar or star) ;*.
