Perhaps you should try some spelling variations:
changes made » changes a, changes due
jin changes » main changes, run changes, jin chang
yang tan » yang yang, liang tan, tang tang
yang fan » zhang fan, yang yang, yang jin
ruan jin » ruan ji, huan jie
made ing » made using, made its
ing von » doing von
dean » dewan, jean, den

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: wang ((((yang tan) OR (yang fan))) OR (yang dean)) ruan jin changes made ing von ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang tan) OR (yang fan))) or (yang dean)) ruan jin changes made ing von ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yang tan) OR (yang fan))) or (yang dean)) ruan jin changes made ing von ;*.
