Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chieu » theo tieu, theo chu, thi chieu
trung cap » truong cao, trung tam
cap thong » cap tong, chap thuong, phap thong
ho chieu » hoc thieu, doi chieu, mot chieu
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
than cau » toan cau, phan cau, than cap

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