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, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tap
tinh he » trinh he, hinh he, tinh ha
he hang » he zhang, le hang, te hang

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 hang ((cong dan) OR (cong tan)) toan cau~.
• Adding a wildcard symbol may retrieve word variants: ((doan tien) or (toan tien)) thanh - canh tinh he hang ((cong dan) or (cong tan)) toan cau*.
