Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
ban thanh » ban hanh, ban hang
thi nhung » thi nang, thi hong, thi hang
thi huong » thi phuong, thi hong, thu huong
doan ban » doanh ban, doan van, doanh bat
cong san » cong tac
toan cau » toan cao, toan tap, toan tai
toan ban » van 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: doan ban thanh - hanh trinh ((thi nhung) OR (thi huong)) cong san ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doan ban thanh - hanh trinh ((thi nhung) or (thi huong)) cong san ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doan ban thanh - hanh trinh ((thi nhung) or (thi huong)) cong san ((toan cau) OR (toan ban))*.
