Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
daun yang » du yang, tan yang, un yang
min keong » kin keong, min keying, min hong
min jeong » kin keong, min hong, mun leong
dan yang » tan yang, wang yang, adam yang
li song » li cong, li rong, kim song
di li » li li

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 ((((dan yang) OR (yang yang))) OR (daun yang)) di li song ((min keong) OR (min jeong)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((dan yang) OR (yang yang))) or (daun yang)) di li song ((min keong) or (min jeong)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((dan yang) OR (yang yang))) or (daun yang)) di li song ((min keong) or (min jeong)) shu ;*.
