Perhaps you should try some spelling variations:
wang yidan » wang yan
liang dan » liang tan, king dan, liang sun
dang hadi » dang hai
wang dan » wang yan, wang ban, wang yang
yang yin » yang jin, yang lin, yang yun
hua dan » hua ban
yang yi » yang di, yang xi, yang jui

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 ((liang dan) OR (((wang dan) OR (wang yidan)))) hua dan ((yang yi) OR (yang yin)) dang hadi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang dan) or (((wang dan) OR (wang yidan)))) hua dan ((yang yi) or (yang yin)) dang hadi ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang dan) or (((wang dan) OR (wang yidan)))) hua dan ((yang yi) or (yang yin)) dang hadi ;*.
