Perhaps you should try some spelling variations:
tieu xanh » tieu danh, chieu xanh, dieu hanh
thong cua » thong quan, thong tu
huong cua » dung cua
bang cong » dang cong, bang song, hang cong
cong tap » cuong tap, cong tac, cong tan
doan cap » doanh cao, dan ca, doan va
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: theo tieu xanh - hanh ((thong cua) OR (huong cua)) bang cong tap ((doan cap) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - hanh ((thong cua) or (huong cua)) bang cong tap ((doan cap) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh ((thong cua) or (huong cua)) bang cong tap ((doan cap) OR (toan cao))*.
