zheng song » zheng rong, hong song, zhen yong
ying yang » yin yang, ying chang, wang yang

• If you are trying to use Boolean operators, they must be ALL CAPS: qian ((ying yang) OR (yang yang)) di ((zheng hong) OR (zheng cong)) zheng song min ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian ((ying yang) OR (yang yang)) di ((zheng hong) or (zheng cong)) zheng song min ;*".
