Perhaps you should try some spelling variations:
ying yang » yin yang, ying chang, wang yang
yang yang » wang yang, wang yan
kong hang » kong heng, kong hong, kong land
dan yang » daun yang, tan yang, wang yang
kang hay » eang hay, kang han, dang hai
yun dan » yun jang
yang xi » yang di, yang yi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((ying yang) OR (yang yang)) yun dan yang xi ((kang hay) or (kong hang)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((ying yang) OR (yang yang)) yun dan yang xi ((kang hay) OR (kong hang)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((ying yang) OR (yang yang)) yun dan yang xi ((kang hay) or (kong hang)) ;*".
