Perhaps you should try some spelling variations:
thanh tung » thanh cong
tieu tinh » trieu tinh, tieu trinh, lieu tinh
tung cua » trung cua, tuong cua, dung cua
cua tong » cua cong, cua dong, cua nong
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
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: theo tieu tinh - thanh tung cua tong ((cong tan) OR (cong tac)) than cau~.
• Adding a wildcard symbol may retrieve word variants: theo tieu tinh - thanh tung cua tong ((cong tan) or (cong tac)) than cau*.
