Perhaps you should try some spelling variations:
wang ying » wang yang, wang yong, wang jing
fang yuan » wang yuhan, wang yan, meng yuan
tang yun » yang yun, chang yun, tang chun
yang jui » yang judy, yang di
kang hay » eang hay, kang han, dang hai
yang yi » yang di
yang xi » yang di

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 ying ((tang yun) OR (fang yuan)) gain ((yang yi) OR (((yang jui) OR (yang xi)))) kang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying ((tang yun) or (fang yuan)) gain ((yang yi) or (((yang jui) OR (yang xi)))) kang hay ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying ((tang yun) or (fang yuan)) gain ((yang yi) or (((yang jui) OR (yang xi)))) kang hay ;*.
