yang lin » yang jin, wang lin, yang li
hong hai » shang hai, zhong tai, dang hai
yang yi » yang jui

• If you are trying to use Boolean operators, they must be ALL CAPS: dong yang yi hua gene ((((yang xi) OR (yang di))) OR (yang lin)) ((hong hai) OR (hong tan)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang yi hua gene ((((yang xi) OR (yang di))) or (yang lin)) ((hong hai) or (hong tan)) ;*".
