Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
than daun » than bau, than daem, than days
than data » than death, loan data, can data
yang jie » yang jin, yang di, yang jui
yang ka » yang fan, yang yao
how ai » how aid, how ae, how asia
how am » how ae

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

• Performing a fuzzy search may retrieve terms with similar spellings: yang yang ka ((than daun) or (than data)) yang jie ((how ai) OR (how am)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang yang ka ((than daun) OR (than data)) yang jie ((how ai) OR (how am)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang ka ((than daun) or (than data)) yang jie ((how ai) OR (how am)) ;*".
