Perhaps you should try some spelling variations:
doanh nhung » doanh thuong, doanh nhan
doanh chung » doanh thuong, doanh chuoi, toan chung
hanh trinh » canh tranh, hanh chinh
doan hung » doan phuong, doan quang, doan trung
theo chu » theo chieu, cho chu, chao chu
chu tach » chu tich, chu thich, chu thanh
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
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 chu tach - hanh trinh ((((doanh nhung) OR (doan hung))) OR (doanh chung)) cong dan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu tach - hanh trinh ((((doanh nhung) OR (doan hung))) or (doanh chung)) cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo chu tach - hanh trinh ((((doanh nhung) OR (doan hung))) or (doanh chung)) cong dan toan cao*.
