Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trung » thanh trung, hanh trang, manh trung
doi chieu » doc hieu, doi chi, ho chieu
trung ap » trung cap, trung lap, trung tam
cong dan » cong san, cong tan, cong dong
than cau » toan cau, than cap, thanh chau
phan cau » phan dau, phan cac, phan tu
ap dung » xay dung, van dung

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: doi chieu xanh - hanh trung ap dung ((cong dan) OR (huong dan)) ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - hanh trung ap dung ((cong dan) or (huong dan)) ((than cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - hanh trung ap dung ((cong dan) or (huong dan)) ((than cau) OR (phan cau))*.
