• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((((yuan chang) OR (han chang))) OR (yuan cheng)) run gain yang yang chong yi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((((yuan chang) OR (han chang))) or (yuan cheng)) run gain yang yang chong yi ;*".
