Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
cua phuong » cuu phuong, cuc phuong, luan phuong
cua khong » hua khong, cua thuong, cua cong
ho chieu » theo chieu, hoc thieu, doi chieu
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
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 xanh - canh tranh ((cua khong) OR (cua phuong)) ((cong tan) OR (cong tac)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - canh tranh ((cua khong) or (cua phuong)) ((cong tan) OR (cong tac)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - canh tranh ((cua khong) or (cua phuong)) ((cong tan) OR (cong tac)) toan cao*.
