• The words AND, OR and NOT may confuse the search; try adding quotes: "((long tan) OR (long han)) wuhan ((china fan) or (china fax)) ((yang xi) or (yang jui)) tong hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((long tan) OR (long han)) wuhan ((china fan) or (china fax)) ((yang xi) or (yang jui)) tong hui ;*.
