Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, truong thanh
theo chuc » theo chu, tho chu, treo chu
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
tang cua » mang cua, hang cua, tang luan
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong ty
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 - hanh tang cua nhung ((cong dan) OR (((cong tan) OR (cong thanh)))) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chuc nang - hanh tang cua nhung ((cong dan) or (((cong tan) OR (cong thanh)))) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo chuc nang - hanh tang cua nhung ((cong dan) or (((cong tan) OR (cong thanh)))) toan cau*.
