Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
zhang hai » zhang dai, shang hai, zhang han
yong yan » yang yang, dong yang, ying yang
yan yun » yan yuan, yang yun, yan kun
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 yan yun dan ((yang xi) OR (yang yi)) zhang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yan yun dan ((yang xi) OR (yang yi)) zhang hai ;*".
