Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
jeong shu » jeong su, cong shu
yan yang » yao yang, tan yang, yan wang
dan yang » daun yang, tan yang, wang yang
cong min » gong min, jong min, song min
cog min » gong min, jong min, song min
xi li » li li, xi ai
wang » wing, wan, lang

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