Perhaps you should try some spelling variations:
thanh trung » thanh tung
thi chieu » thi chien, thi hieu, theo chieu
trung dap » trung cap, trung dai, trung dam
dap dang » da dang, dai dang, nap dang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
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: ((thi chieu) OR (theo tieu)) xanh - thanh trung dap dang ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi chieu) or (theo tieu)) xanh - thanh trung dap dang ((cong dan) OR (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((thi chieu) or (theo tieu)) xanh - thanh trung dap dang ((cong dan) OR (cong tan)) toan cau*.
