Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
hyoung ben » hyoung gun, yong ben
yang yang » wang yang, wang yan
yang ka » yang fan, yang yao
yang yi » yang di, yang xi, yang jui
a books » _ books, a book, e books
1 loan » _ loan, 3 loan
loan a » loan _

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: ((((yang ka) OR (yang yang))) OR (yang yi))nr 1 loan a books lang hyoung ben ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yang ka) or (yang yang))) or (yang yi))nr 1 loan a books lang hyoung ben ;*.
