Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chuc danh » chuc nganh, thuc hanh, chuc nang
chua nang » chuc nang, chua xang, kha nang
hanh dung » thanh dung, anh dung, hanh dong
cua nhung » va nhung
dung cua » dung luan, dung cho
dan toan » van toan, dan than, manh toan
van tan » van tuan, van ban, van tai

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