Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trang » thanh trung, canh tranh, hanh trinh
cua thong » cua thuong, cua tong, suat thong
cua khong » hua khong, cua phuong, cua thuong
ho chieu » theo chieu, hoc thieu, doi chieu
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan tap, toan tai
toan ban » van ban

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 xanh - hanh trang ((cua thong) OR (cua khong)) cong tan ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trang ((cua thong) or (cua khong)) cong tan ((toan cau) or (toan ban))*.
