Perhaps you should try some spelling variations:
doanh hoan » doanh doanh, doanh khoa, doanh nhan
canh doanh » hanh doanh, chinh doanh, doanh doanh
dung cong » dung trong
thi hanh » thi thanh
cua dung » cua dang, cua dong, qua dung
cong van » cong vang, cong san, song van
doi thi » doi thoi, do thi, doi khi
tuan cu » tuan tu, quan cua, tuan thu
tran tu » tran tuan, tran thuy, tran thi

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: doi thi hanh - ((canh doanh) OR (doanh hoan)) cua dung cong van ((tuan cu) OR (tran tu))~.
• Adding a wildcard symbol may retrieve word variants: doi thi hanh - ((canh doanh) or (doanh hoan)) cua dung cong van ((tuan cu) or (tran tu))*.
