yang jui » yang judy, yang di, yang xi
long shu » cong shu, tong shui, long du
gun hua » gui hua, tuan hua

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hyoung gun hua rein ((yan jiu) or (((pang jun) OR (yang jui)))) long shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang hyoung gun hua rein ((yan jiu) or (((pang jun) OR (yang jui)))) long shu ;*.
