Perhaps you should try some spelling variations:
when changes » when change, been changes, when chance
changes made » changes a, changes due
yang jui » yang judy, yang di, yang xi
jui gang » ii gang, zum gang, gai gang
gang yao » yang yao, wang yan, ganga ya
yao when » do when, so when, bay when
wong sau » wong sam, wong siu, wong shiu

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: yang jui gang yao when changes made ((cong shu) OR (wong sau)) ;~.
• Adding a wildcard symbol may retrieve word variants: yang jui gang yao when changes made ((cong shu) or (wong sau)) ;*.
