Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tieu xanh » tieu danh, chieu xanh, dieu hanh
hang cua » mang cua, hang ca, huong cua
manh cua » doanh cua, ban cua
cong dan » cong san, cong tan, huong dan
than cap » khan cap, thanh lap, thanh cac
toan ban » van ban

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 - hanh ((hang cua) OR (manh cua)) nhung cong dan ((than cap) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh ((hang cua) or (manh cua)) nhung cong dan ((than cap) or (toan ban))*.
