Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
trung tuan » trung thanh, trung tam, tran tuan
nhung cong » dung cong, thong cong, hang cong
trung cap » truong cao, trung tam
cong dan » cong san, cong tan, huong dan
than cau » phan cau, than cap, thanh chau
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: theo chieu xanh - thanh ((trung cap) OR (trung tuan)) nhung cong dan ((than cau) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - thanh ((trung cap) or (trung tuan)) nhung cong dan ((than cau) OR (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - thanh ((trung cap) or (trung tuan)) nhung cong dan ((than cau) OR (toan cau))*.
