Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh dung » thanh dung, anh dung, hanh dong
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
van cong » van dong, van phong, phan cong
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 ((chieu xanh) OR (chinh sach)) - hanh dung (luan OR lan) van cong manh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chinh sach)) - hanh dung (luan OR lan) van cong manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chinh sach)) - hanh dung (luan OR lan) van cong manh toan cau*.
