Perhaps you should try some spelling variations:
doanh doanh » doanh hoan, doanh thanh, dong doanh
theo chieu » theo tieu, ho chieu, thi chieu
cong cong » cong dong, trong cong, dung cong
theo chu » cho chu, chao chu, theo yeu
cong ban » cong bang, cong san, cong tan
ban toan » bai toan, ban than, 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: ((theo chieu) OR (theo chu)) sang - ((doanh doanh) OR (toan doanh)) cua cong cong ban toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (theo chu)) sang - ((doanh doanh) or (toan doanh)) cua cong cong ban toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (theo chu)) sang - ((doanh doanh) or (toan doanh)) cua cong cong ban toan cau*.
