Perhaps you should try some spelling variations:
past mass » past pasts, past case, past has
mass when » ass when, cases when, bars when
yang yang » wang yang, wang yan
dang haji » dang hai, dato haji
yang jie » yang jin, yang xi, yang yi
yang jui » yang judy, yang xi, yang yi
we shen » wei shen, we spend

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: past mass when we shen ((((((yang yang) OR (yang jie))) OR (yang jui))) OR (yang di)) dang haji ;~.
• Adding a wildcard symbol may retrieve word variants: past mass when we shen ((((((yang yang) or (yang jie))) or (yang jui))) or (yang di)) dang haji ;*.
