Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, dan yang
yang yang » wang yang, wang yan
from west » from waste
dong cao » dong xiao, dan cao, dong nan
ya from » a from, yoga from, dna from
can jiu » can join, pang jiu
yan jiu » yang jie, yang jin, pang jiu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong cao) or (((dong yang) or (yang yang)))) ya from west ((can jiu) OR (yan jiu)) cong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong cao) OR (((dong yang) OR (yang yang)))) ya from west ((can jiu) OR (yan jiu)) cong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong cao) or (((dong yang) or (yang yang)))) ya from west ((can jiu) OR (yan jiu)) cong shu ;*".
