Perhaps you should try some spelling variations:
doan tien » doan thien, doanh tien, doan dien
canh tinh » hanh tinh, manh tinh, canh tranh
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap
he bang » te bang, ke bang, le bang
de bang » den bang, de dang, de tang

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: ((doan tien) OR (toan tien)) thanh - canh tinh ((he bang) OR (de bang)) cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doan tien) or (toan tien)) thanh - canh tinh ((he bang) OR (de bang)) cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((doan tien) or (toan tien)) thanh - canh tinh ((he bang) OR (de bang)) cong dan toan cau*.
