Perhaps you should try some spelling variations:
shin keong » kin keong, shin dong
keong shu » cong shu, jeong su
lang yan » wang yan, wang yang, zhang yan
yang jui » yang judy, yang yi
yang xi » yang yi
yang mu » yang du, yang muxi, yang jun
li song » li cong, li rong, kim song

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: lang yan ((((((yang di) OR (yang xi))) OR (yang mu))) OR (yang jui)) li song shin keong shu ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ((((((yang di) or (yang xi))) or (yang mu))) or (yang jui)) li song shin keong shu ;*.
