Perhaps you should try some spelling variations:
nhung cong » thong cong, nhung don, nhung lang
tranh cua » doanh cua, manh cua
hang cong » dang cong, hang nong, bang cong
dung cong » dung trong
ho trieu » mot trieu, 25 trieu, 30 trieu
van toan » van tuan, van tan, van thanh
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: ho trieu tinh - canh tranh cua ((((nhung cong) OR (hang cong))) OR (dung cong)) van toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - canh tranh cua ((((nhung cong) OR (hang cong))) or (dung cong)) van toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - canh tranh cua ((((nhung cong) OR (hang cong))) or (dung cong)) van toan cau*.
