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

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