Perhaps you should try some spelling variations:
making asean » making lean, leading asean, making case
asean region » andean region, ocean region, urban region
yan making » lean making, plan making, un making
zhang yan » zhang fan, zhang jian, wang yan
yang jui » yang judy, yang xi
wong siu » wong shiu, kong siu, wong sau
yang yi » yang xi

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: zhang yan making asean region ((((yang yi) OR (yang jui))) OR (yang di)) wong siu ;~.
• Adding a wildcard symbol may retrieve word variants: zhang yan making asean region ((((yang yi) or (yang jui))) or (yang di)) wong siu ;*.
