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
dan yang » daun yang, tan yang, wang yang
yang jin » yang jie, yang jun, shang jin
ying jin » jing ji, yang jie
how ai » how aid, how ae, how am

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

• If you are trying to use Boolean operators, they must be ALL CAPS: dan yang yang ((than daun) OR (than data)) ((yang jin) OR (ying jin)) how ai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dan yang yang ((than daun) or (than data)) ((yang jin) OR (ying jin)) how ai ;~".
• Adding a wildcard symbol may retrieve word variants: dan yang yang ((than daun) or (than data)) ((yang jin) OR (ying jin)) how ai ;*.
