Perhaps you should try some spelling variations:
yong hoang » dong hoang, hong hong, kong hang
wang yong » wang yang, wang hyoung, wang yan
hoang yi » hoang vu, yang yi, hoang sy
wang lin » wang li, wang qin, yang lin
hong hai » shang hai, zhong tai, hong tan
wong yue » wang yue
yi wang » li wang, yi gang, yi yang
lin li » ling li, lin yi, yin li

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 hoang yi wang lin li ((((hong hai) OR (dang hai))) OR (((hong yu) OR (wong yue)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong hoang yi wang lin li ((((hong hai) OR (dang hai))) or (((hong yu) or (wong yue)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong hoang yi wang lin li ((((hong hai) OR (dang hai))) or (((hong yu) or (wong yue)))) ;*.
