Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh doanh » hang doanh, chinh doanh, doanh doanh
doanh luan » doanh nhan
phong cong » phong chong, thong cong, phong dong
chong cong » cong cong, thong cong, cuong cong
hien xanh » hien hanh, hien nhanh, hien khanh
dan toan » van toan, dan than, manh toan
toan cau » 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: hoc ((hien xanh) OR (chieu xanh)) - hanh doanh luan ((phong cong) OR (chong cong)) dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (chieu xanh)) - hanh doanh luan ((phong cong) OR (chong cong)) dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (chieu xanh)) - hanh doanh luan ((phong cong) OR (chong cong)) dan toan cau*.
