Perhaps you should try some spelling variations:
chieu tinh » lieu tinh, chau tinh, kieu tinh
cong thanh » dong thanh, cong trinh, cong tan
canh manh » lanh manh, canh tranh, cach mang
cua nhung » va nhung
cong manh » cong danh, duong manh, hoang manh
manh cua » doanh cua, ban cua
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 (trieu tinh)) - canh manh cua nhung ((cong manh) OR (cong thanh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu tinh) OR (trieu tinh)) - canh manh cua nhung ((cong manh) or (cong thanh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu tinh) OR (trieu tinh)) - canh manh cua nhung ((cong manh) or (cong thanh)) toan cau*.
