wan yan » wang yan, nan yan, wai yan
yang xi » yang di, yang yi, yang jui
yu yang » du yang, yu fang, yu gang
yi yang » yin yang, yi gang, ying yang
di song » li song, kim song, jie song

• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((((yang xi) OR (wang hua))) OR (yang hui)) ((yu yang) OR (yi yang)) di song shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((((yang xi) or (wang hua))) or (yang hui)) ((yu yang) OR (yi yang)) di song shu ;*".
