Perhaps you should try some spelling variations:
using des » using pdes, using aes, using dbs
bias when » bars when
yang yang » wang yang, wang yan
des bias » des ias, des bilans, des biens
when how » when do
how min » how men, how many, show mid
yang xi » yang jui
yang yi » yang jui
line » life

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "line using des bias when how min ((((yang yang) OR (yang xi))) OR (((yang yi) OR (yang di)))) ;~".
• Adding a wildcard symbol may retrieve word variants: line using des bias when how min ((((yang yang) OR (yang xi))) OR (((yang yi) OR (yang di)))) ;*.
