Perhaps you should try some spelling variations:
hard things » hard thing, bad things, smart things
ying yang » yang yang, yin yang, ying chang
using dea » using dna, using delta, using ideal
using dem » using dhm, using deep, using ddms
hua hard » a hard, eu hard, up hard
yu yang » du yang, yi yang, yu fang

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((ying yang) or (yu yang)) wang hua hard things ((using dea) OR (using dem)) bei ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ying yang) OR (yu yang)) wang hua hard things ((using dea) OR (using dem)) bei ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ying yang) or (yu yang)) wang hua hard things ((using dea) OR (using dem)) bei ;*".
