Perhaps you should try some spelling variations:
hyoung yang » kyoung yang
han chang » huang chang, than change, can change
chang won » chang soon, chang ann, chang min
shang hai » shang kai, chang ha, hong hai
yang xi » yang di, yang yi, yang jui
hong yu » wong yue
xi han » ti han, xi zhang
wang » wing, wan, lang

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 hyoung yang xi han chang won ((((shang hai) OR (dang hai))) OR (hong yu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang hyoung yang xi han chang won ((((shang hai) or (dang hai))) or (hong yu)) ;*.
