Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tieu xanh » tieu danh, chieu xanh, dieu hanh
mang cua » dung cua, cong cua, dong cua
manh cua » doanh cua
cong tac » cong ty
tac doan » tap doan, tan doan, thai doan
doan cau » toan cau, doan dau, doan cap
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 tieu xanh - nhanh ((((mang cua) OR (manh cua))) OR (ban cua)) nhung cong tac doan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - nhanh ((((mang cua) OR (manh cua))) or (ban cua)) nhung cong tac doan cau~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - nhanh ((((mang cua) OR (manh cua))) or (ban cua)) nhung cong tac doan cau*.
