Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yan yang » yang yang, dan yang, yan wang
yao yang » yang yang
tan yang » dan yang, tan ying, tan yong
tao yang » xiao yang, dan yang, gao ying
yi dang » yi gang, yi yang, yi chang
hai » hadi, haji, hari

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wan ((((yan yang) OR (yao yang))) or (tan yang)) di ((wang yang) or (tao yang)) yi dang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((((yan yang) OR (yao yang))) OR (tan yang)) di ((wang yang) OR (tao yang)) yi dang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((((yan yang) OR (yao yang))) or (tan yang)) di ((wang yang) or (tao yang)) yi dang hai ;".
• Adding a wildcard symbol may retrieve word variants: wan ((((yan yang) OR (yao yang))) or (tan yang)) di ((wang yang) or (tao yang)) yi dang hai ;*.
