Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chieu » theo tieu, ho chieu, theo chu
chieu tinh » trieu tinh, lieu tinh, chau tinh
trung tuan » trung thanh, trung tam, tran tuan
tuan ban » tuan bang, luan ban, quang ban
ban cong » bang cong, van cong, phan cong
cong tan » cong tac, cong san, cong thanh
toan cau » toan tap, toan tai
toan cao » toan tap
toan ban » van ban

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