Perhaps you should try some spelling variations:
wang yidan » wang yan
fang yang » wang yang, yang yang, huang yang
wang dan » wang yan, wang yang, liang dan
wang ban » wang yan, wang yang, bang bang
yu fang » yu gang, yu wang, yu yang
yang yi » yang di, yang xi, yang jui
yi yang » yin yang, yi gang, yu yang
yun yu » lun yu

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang dan) OR (wang ban))) OR (wang yidan)) yun yu fang yang yi yang (hai OR hadi) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang dan) OR (wang ban))) or (wang yidan)) yun yu fang yang yi yang (hai or hadi) ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang dan) OR (wang ban))) or (wang yidan)) yun yu fang yang yi yang (hai or hadi) ;*.
