Perhaps you should try some spelling variations:
yuan kang » yuan wang, yuan chang, chan kang
wang yong » wang yang, wang hyoung, wang yan
guang hai » dang hai, shang hai
yong yan » yang yang, dong yang, ying yang
yuan kai » yuan fei, tan kai, yuan hui
yang jui » yang judy, yang di, yang xi
tan kah » tan ah, tan kai
yang wu » yang du, yang mu, yang jun

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 yong yan ((((yuan kai) OR (yuan kang))) OR (tan kah)) ((yang wu) OR (yang jui)) guang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yan ((((yuan kai) OR (yuan kang))) or (tan kah)) ((yang wu) or (yang jui)) guang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yan ((((yuan kai) OR (yuan kang))) or (tan kah)) ((yang wu) or (yang jui)) guang hai ;*.
