Perhaps you should try some spelling variations:
manh trung » manh tung, thanh trung, manh hung
hanh trinh » canh tranh, hanh chinh
thong cong » trong cong, tong cong, thong thong
cua thong » cua thuong, cua khong, cua tong
ho trieu » mot trieu, 25 trieu, 30 trieu
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban

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 - ((manh trung) OR (hanh trinh)) cua thong cong tan ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - ((manh trung) or (hanh trinh)) cua thong cong tan ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - ((manh trung) or (hanh trinh)) cua thong cong tan ((toan cau) OR (toan tap))*.
