Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trang » thanh trung, hanh trinh, minh trang
ho chieu » theo chieu, hoc thieu, doi chieu
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
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 - ((hanh trang) OR (canh tranh)) cua dung ((cong dan) OR (cong tan)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh trang) OR (canh tranh)) cua dung ((cong dan) or (cong tan)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh trang) OR (canh tranh)) cua dung ((cong dan) or (cong tan)) toan cao*.
