• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang luhang) OR (wang liang)) fang ((yu cheng) or (yuan chang)) zhang tax cost shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang luhang) OR (wang liang)) fang ((yu cheng) or (yuan chang)) zhang tax cost shu ;*.
