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, truong thanh
nhung cong » dung cong, thong cong, hang cong
tran tuan » tran xuan, tran quang, tran thanh
cong ban » cong bang, cong san, cong tan
than cau » toan cau, than cap, thanh chau
phan cau » phan dau, phan cac, phan tu

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 tuan) OR (tran tuan)) nhung cong ban ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - thanh ((trung tuan) or (tran tuan)) nhung cong ban ((than cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - thanh ((trung tuan) or (tran tuan)) nhung cong ban ((than cau) OR (phan cau))*.
