yang hua » wang hua, yang hui, ying hua
hua gene » human gene, a gene, hua ren
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang jui, yang xi

non same » non state, non frame, non sales

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 yang yang hua gene ((yang jin) OR (yang jie)) ((non sacu) OR (non same)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang hua gene ((yang jin) or (yang jie)) ((non sacu) OR (non same)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yang hua gene ((yang jin) or (yang jie)) ((non sacu) OR (non same)) ;*.
