Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
cong thanh » dong thanh, cong trinh, truong thanh
doan tien » doan thien, doanh tien, toan tien
he nhung » hee nhung, ve nhung, hien nhung
me nhung » ve nhung, ma nhung, my nhung
cong tan » cong tac, cong san, cong ty
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 tien thinh - hanh trinh ((he nhung) OR (me nhung)) ((cong tan) OR (cong thanh)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doan tien thinh - hanh trinh ((he nhung) or (me nhung)) ((cong tan) OR (cong thanh)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: doan tien thinh - hanh trinh ((he nhung) or (me nhung)) ((cong tan) OR (cong thanh)) toan cao*.
