Perhaps you should try some spelling variations:

cong thanh » dong thanh, cong trinh, truong thanh
chau tinh » cuu tinh, cua tinh, cac tinh
thanh tra » thanh toan, thanh hoa
tra tuan » tran tuan, tra quan, tri tuan
cong tan » cong tac, cong san, cong ty
toan cau » toan cao, toan ban, toan tap
ha tinh » va tinh, may tinh

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: o ((chau tinh) OR (ha tinh)) - thanh tra tuan trong ((cong tan) OR (cong thanh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "o ((chau tinh) or (ha tinh)) - thanh tra tuan trong ((cong tan) OR (cong thanh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: o ((chau tinh) or (ha tinh)) - thanh tra tuan trong ((cong tan) OR (cong thanh)) toan cau*.
