Perhaps you should try some spelling variations:
wang yidan » wang yan
wang dan » wang yan, wang ban, wang yang
tan yang » dan yang, tan ying, tan yong
jan run » can run, bank run
run tan » run gain, run pain
yang yi » yang di, yang xi, yang jui
yi dang » yi gang, yi yang, yi chang

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang dan) OR (wang yidan)) jan run tan yang yi dang (hai or hadi) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang dan) OR (wang yidan)) jan run tan yang yi dang (hai OR hadi) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) OR (wang yidan)) jan run tan yang yi dang (hai or hadi) ;".
• Adding a wildcard symbol may retrieve word variants: ((wang dan) OR (wang yidan)) jan run tan yang yi dang (hai or hadi) ;*.
