Perhaps you should try some spelling variations:
societal needs » societal levels, societal norms
yanling yang » yang yang, ying yang
social needs » special needs, social norms
tan long » tan hong, tan kong, tan yong
long seo » hong seo, long ago, long des
can tan » can tax, tan tan, can stand

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

• Performing a fuzzy search may retrieve terms with similar spellings: (wing or wan) yanling yang ((societal needs) OR (social needs)) can tan long seo ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR wan) yanling yang ((societal needs) OR (social needs)) can tan long seo ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wing or wan) yanling yang ((societal needs) OR (social needs)) can tan long seo ;*".
