Perhaps you should try some spelling variations:
doanh tien » doanh tren, doanh vien, doanh chien
hanh trinh » canh tranh, hanh chinh
cong thanh » dong thanh, cong trinh, truong thanh
trinh han » trinh quan
han hang » hang hang, han chang, ban hang
cong tan » cong tac, cong san, cong ty
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doanh tien thinh - hanh trinh han hang ((cong tan) OR (cong thanh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: doanh tien thinh - hanh trinh han hang ((cong tan) OR (cong thanh)) toan cau*.
