Perhaps you should try some spelling variations:
chua xang » chua nang, chu bang, chua dong
cua nhung » va nhung
anh tang » anh bang, anh dang, anh nang
tang cua » mang cua, hang cua, tang luan
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
toan cau » toan cao, toan ban, toan tap

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 nang) OR (chua xang)) - anh tang cua nhung ((cong dan) OR (cong san)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chuc nang) or (chua xang)) - anh tang cua nhung ((cong dan) OR (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chuc nang) or (chua xang)) - anh tang cua nhung ((cong dan) OR (cong san)) toan cau*.
