Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
luan nhung » luan chung, luan hung, quan nhung
chua nang » chuc nang, chua xang, kha nang
hanh dung » thanh dung, anh dung, hanh dong
chu bang » thu bang, chuc nang, chu quang
dan toan » van toan, dan than, manh toan
van tuan » van quan, van ban, anh tuan

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