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