yang yang » wang yang, wang yan
hai phong » bai chong, kai hong
phong shu » cong shu
yan yang » yao yang, dan yang, tan yang
wang » wing, wan, lang

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yang) OR (yang yang)) pui ((shen chang) OR (chin chang)) hai phong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) OR (yang yang)) pui ((shen chang) or (chin chang)) hai phong shu ;*".
