Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
truong cao » truong dai
hoc chieu » hoc thieu, ho chieu, hoc hien
trung cap » trung tam
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
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: hoc chieu xanh - thanh ((trung cap) OR (truong cao)) nhung ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - thanh ((trung cap) OR (truong cao)) nhung ((cong dan) or (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - thanh ((trung cap) OR (truong cao)) nhung ((cong dan) or (cong tan)) toan cau*.
