Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
doanh cua » doanh luan
cong tac » cong ty
tac tuan » tac quan, ta tuan, tai tuan
tuan cau » toan cau, quan cau, tuan cu
ban cua » ban quan

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 chieu xanh - hanh ((((manh cua) OR (doanh cua))) OR (ban cua)) nhung cong tac tuan cau~.
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - hanh ((((manh cua) or (doanh cua))) or (ban cua)) nhung cong tac tuan cau*.
