Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
thi chien » thi hien, thi thien, thien chien
hanh tang » hanh trang, anh tang, hanh mang
cong danh » cuong danh, cong dan, cong khanh
ho chieu » theo chieu, hoc thieu, doi chieu
tang cua » mang cua, hang cua, tang luan
cua bang » chua bang, cua ban, cua dang
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: ((ho chieu) OR (thi chien)) xanh - hanh tang cua bang ((cong danh) OR (cong thanh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (thi chien)) xanh - hanh tang cua bang ((cong danh) OR (cong thanh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (thi chien)) xanh - hanh tang cua bang ((cong danh) OR (cong thanh)) toan cau*.
