Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang shiyong
yong yang » yang yang, dong yang, ying yang
han chang » huang chang, than change, can change
chang won » chang soon, chang ann, chang min
wang yue » wong yue, wang hua, wang he
di han » ti han
yang » ryang
yan » ryan

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 yang di han chang won ((dang hai) OR (((wang yue) OR (wang yan)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yang di han chang won ((dang hai) or (((wang yue) OR (wang yan)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yang di han chang won ((dang hai) or (((wang yue) OR (wang yan)))) ;*.
