sharing a » sharing _
lang yan » wang yan, wang yang, zhang yan
yang run » yang jun, bank run, yang jui
yang yun » yang jun, tang yun, yang yue
hong yu » wong yue
a hong » _ hong, kia hong, tan hong

• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((((yang run) OR (yang yun))) OR (long run)) cost sharing a hong yu ;*.
