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