managing channel » managing change, managing tunnel, marketing channel
best bring » best thing, best breaking
bring ong » bring out
chae yuan » chae yun, chiao yuan, chu yuan

chang su » chang hsun, chang fwu, chang gui

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: making ((managing changes) OR (managing channel)) can best bring ong ((chang su) OR (chae yuan)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "making ((managing changes) OR (managing channel)) can best bring ong ((chang su) or (chae yuan)) ;~".
• Adding a wildcard symbol may retrieve word variants: making ((managing changes) OR (managing channel)) can best bring ong ((chang su) or (chae yuan)) ;*.
