chua nang » chuc nang, chua xang, kha nang
hanh dung » thanh dung, anh dung, hanh dong
cua nhung » va nhung
chu bang » thu bang, chuc nang, chu quang
dung cua » dung luan, dung cho
dan toan » dan than, manh toan, xuan toan
van toan » van tuan, van tan, van thanh

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: theo ((chua nang) OR (chu bang)) - hanh dung cua nhung cong ((dan toan) OR (van toan)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chua nang) or (chu bang)) - hanh dung cua nhung cong ((dan toan) or (van toan)) cau*.
