Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, kieu tinh
chau tinh » cuu tinh, ha tinh, cua tinh
hua khong » hoa khong, cua khong, hoac khong
cua tong » cua cong, cua dong, cua nong
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
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: doi ((chieu tinh) OR (chau tinh)) - canh tranh ((cua tong) OR (hua khong)) cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu tinh) OR (chau tinh)) - canh tranh ((cua tong) or (hua khong)) cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu tinh) OR (chau tinh)) - canh tranh ((cua tong) or (hua khong)) cong tan toan cau*.
