Perhaps you should try some spelling variations:
wang yong » wang hyoung, wang yan, wang shiyong
wang yang » wang yan, wang liang, wang yanling
zhang hai » zhang dai, shang hai, zhang han
yang yun » yang jun, tang yun, yang yue
yun dan » yun jang
yang xi » yang di, yang jui
yang yi » yang di, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yong) OR (wang yang)) yang yun dan ((yang xi) or (yang yi)) zhang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yong) OR (wang yang)) yang yun dan ((yang xi) OR (yang yi)) zhang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) OR (wang yang)) yang yun dan ((yang xi) or (yang yi)) zhang hai ;*".
