Perhaps you should try some spelling variations:
min hyoung » min hong, mun young
chen chan » cheung chan, chen chung, shen chang
wang yang » wang yan, wang liang, wang yanling
hyoung su » hyoung gun, hyoung il
wan yan » wang yan, nan yan, qian yan
wai yan » wang yan, wei yang
yuan li » yuan lin, guan li, yuan zi

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: ((((wan yan) OR (wang yang))) OR (wai yan)) yuan li ((chen chan) OR (chen chuan)) min hyoung su ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wan yan) OR (wang yang))) or (wai yan)) yuan li ((chen chan) or (chen chuan)) min hyoung su ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) OR (wang yang))) or (wai yan)) yuan li ((chen chan) or (chen chuan)) min hyoung su ;*.
