Perhaps you should try some spelling variations:
kang minah » sang minh
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
song ming » song bing, song min, gong min
der rent » der re
der rede » der redner, der re
how seo » how so, how self, how secs

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang yong yang ((der rent) OR (der rede)) ((song ming) or (kang minah)) how seo ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong yang ((der rent) OR (der rede)) ((song ming) OR (kang minah)) how seo ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yang ((der rent) OR (der rede)) ((song ming) or (kang minah)) how seo ;*".
