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