Perhaps you should try some spelling variations:
chang chen » chang ch'un, chang chuan, change when
hyoung yan » kyoung yang, hyoung gun, kyoung yun
kang chen » jane chen, kang han, tang chun
yan yuan » yan guan, fang yuan, nan yan
yuan dan » yuan kang, yuan wang, yuan kai
dan yang » daun yang, tan yang, wang yang
yang jui » yang judy, yang di, yang xi
wang » wing, wan, lang
hai » hadi, haji, hari

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 yan yuan dan yang jui ((((kang chen) OR (chang chen))) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hyoung yan yuan dan yang jui ((((kang chen) OR (chang chen))) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang hyoung yan yuan dan yang jui ((((kang chen) OR (chang chen))) or (dang hai)) ;*.
