Perhaps you should try some spelling variations:
thanh trung » thanh tung
doi chieu » doc hieu, doi chi, mot chieu
trung cua » truong cua, trung tuan, trung cap
ho chieu » theo chieu, hoc thieu, mot chieu
cua nong » cua cong, cuu nong, cua dong
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
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: ((doi chieu) OR (ho chieu)) sang - thanh trung cua nong ((cong dan) OR (cong san)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (ho chieu)) sang - thanh trung cua nong ((cong dan) or (cong san)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (ho chieu)) sang - thanh trung cua nong ((cong dan) or (cong san)) phan cau*.
