Perhaps you should try some spelling variations:
klarung der » klarung des, erklarung der, erklarung des
how slowme » how some, how slower
wang yong » wang yang, wang hyoung, wang yan
klang der » gang der
sang minh » kang minah, anh minh, song min
how slow » how low, how slower, grow slow
re sang » le sang, lee sang

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 ((klang der) OR (klarung der)) re sang minh ((how slow) OR (how slowme)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((klang der) OR (klarung der)) re sang minh ((how slow) or (how slowme)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((klang der) OR (klarung der)) re sang minh ((how slow) or (how slowme)) ;*.
