Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
chu manh » ho manh, chu han, chu van
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 ((chu manh) OR (chieu xanh)) - hanh tang cua nhung ((cong dan) OR (cong san)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu manh) or (chieu xanh)) - hanh tang cua nhung ((cong dan) OR (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu manh) or (chieu xanh)) - hanh tang cua nhung ((cong dan) OR (cong san)) toan cau*.
